06/28/22 03:16 PM Canada - Chevrolet Grand Prix 2022 by teamzr1
For the first time since 2019, Corvette Racing and the rest of the IMSA WeatherTech SportsCar Championship is back at Canadian Tire Motorsport Park for Sunday’s Chevrolet Grand Prix.

Absent from the team’s calendar since the beginning of the COVID-19 pandemic, the 2.459-mile, 10-turn road course just outside of Toronto will see the mid-engine Chevy Corvette C8.R for the first time. It will be the fourth generation of Corvette to compete at CTMP since the Corvette Racing program first raced there in 2000 with the Corvette C5-R.

Since that time, the team has claimed 11 victories at the track second-most among all venues, behind only Sebring.
Three of those came in Corvettes driven by Canadian and Corvette Racing legend Ron Fellows, who is co-owner of Canadian Tire Motorsport Park.

Antonio Garcia and Jordan Taylor are part of a six-car field in the GT Daytona (GTD) PRO category, which is part of a 14-car grid in the overall GTD category. The pairing will look to rebound from a disappointing race in the Sahlen’s Six Hours of The Glen two days ago.
The No. 3 Mobil 1/SiriusXM Corvette C8.R finished sixth in the GTD PRO class and 11th among GTD category runners.

Both drivers have victories to their credit at CTMP in Corvette racecars. Garcia won the GT Le Mans (GTLM) category in 2014, driving a Corvette C7.R with Jan Magnussen. Taylor was victorious the following year in a Corvette Daytona Prototype for Wayne Taylor Racing.

Garcia also is a former pole-winner at Canadian Tire Motorsport Park (2016) and set the fastest GTLM race lap in 2015.

The Chevrolet Grand Prix at Canadian Tire Motorsport Park is scheduled for 3:05 p.m. ET on Sunday, July 3.
The race will air live on NBC and stream live on Peacock inside the United States and IMSA.com outside the U.S. IMSA Radio will air on-track sessions beginning with Saturday morning’s practice at IMSA.com with the race call also on XM 207 and SiriusXM Online 992.

ANTONIO GARCIA, NO. 3 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“I would have loved to go to Canadian Tire Motorsport Park and raced the C8.R in full GTLM spec. That would have been wonderful to feel and see how the C8.R was around that track. We knew the C7.R was so good, and I believe this car would have been even better. This is always a track I’ve always loved. It’s always tight racing, and traffic is intense. Strategy is important with such a short lap time because it’s very fast.

You need to be on top of things, play it smart and be ready to react to everything around you. It can go either way. But CTMP always brings a perfect show and good racing. We’re looking forward to getting back there.
It’s a track where I’ve done many, many laps in the past. I don’t think things will be way different. Coming from The Glen, I think we’ll be ready to get right into things at CTMP.”

JORDAN TAYLOR, NO. 3 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Going to Canadian Tire Motorsport Park is something we’ve missed. Canada always has an amazing group of fans who are so passionate.
The last time they saw Corvette Racing, it was with the C7.R. So they haven’t seen our new car, and we’re excited to show it off there.

What we’ve seen so far with the C8.R is that it suits every type of racetrack. We saw last year at Watkins Glen how successful it was at a high-speed track, and that’s kind of what CTMP is. I think our car will suit the track well, and I know we bring an amazing amount of Corvette fans there.
They’ll definitely love seeing it.”

06/28/22 01:16 PM What not to Do when changing DCT Filter by teamzr1
C8 owner decided he would change the external filter of DCT

Clearly over torqued the bolts and snapped them off in the filter case mad

06/23/22 10:09 PM To save a few GM Bucks, Big Repair Costs to 2023 C8 owners by teamzr1
GM is now saying that beginning with the 2023+ Corvette models, they are doing away with the cylinder key lock mechanism for the rear hatch.
For access to the rear hatch, they suggest using any of the three electronic buttons (driver’s side door, key fob, hatch release button) first.
In case there is an issue with the latching mechanism that has seized, or loss of battery voltage, the only solution for opening it is to use a 3-inch hole-saw and drill into the hatch so that the fasteners holding it closed can be released.

Here is the technical update from GM :

If you need to access the rear compartment on a 2023+ model year Corvette:

Attempt to open the rear hatch /rear compartment using all 3 electrical attempts.
Try the interior switch, the exterior touchpad, and the key fob.
This will electrically command the rear hatch/rear compartment to release.
There is no alternate method to gain access to the rear hatch / rear compartment if these attempts do not work.

The vehicle will have to be damaged in order to open the rear hatch / rear compartment.
See the section later in this document titled, “Accessing the rear hatch / rear compartment with a seized up latch.”

Accessing the rear hatch / rear compartment with a seized up latch:

First, obtain a 3-inch hole saw for the following procedure.

Send the vehicle to a body shop as needed.
Starting at the trailing edge of the rear hatch / rear compartment, measure forward 3 and 1/2".
Make this mark at the centerline of the panel.
This will be the center of the hole that will have to be drilled into the panel.
This will place the pilot hole location right in a portion of the stingray emblem when it has been positioned properly.
Drill a 3" hole through the rear hatch / rear compartment panel.

This will allow the technician to lift the rear panel upwards, and the 3" cut-out portion of the panel will stay attached to the rear latch / striker assembly.
The servicing technician will then have access to the fasteners that hold the latch to the vehicle and can continue servicing the vehicle from there.”

The hatch will then have to be replaced

We’re not exactly sure why this change was made, but most likely it comes down to the cost of the locks and installing them on every C8 Corvette versus the costs to warranty a defective hatch mechanism whenever those issues arise.

Imagine if this happens when the car is out of GM warranty and the total cost to replace the hatch, all for GM to save a few bucks on a lock

06/22/22 11:13 PM Who Louis Chevrolet was by teamzr1
The story behind Chevrolet starts with the name of its founder, Louis Chevrolet, a man from Switzerland who immigrated to the United States in 1901.

During the following years, Louis Chevrolet worked himself until becoming a popular race car driver.
Together with his brother Arthur and William Durant, they founded Chevrolet Motors in 1911 but sadly, the founders departed from Chevrolet Motors before it became one of the biggest car companies in America...

This is the Untold Story of Chevrolet and the co-founder that bears the company's name; Louis Chevrolet.

06/22/22 06:46 PM IMSA Sahlen’s Six Hours of The Glen by teamzr1
While their run at the 24 Hours of Le Mans ended with disappointment, Antonio Garcia, Jordan Taylor and the rest of Corvette Racing’s squad in the IMSA WeatherTech SportsCar Championship are back stateside for another shot at a long-distance race victory.

The Sahlen’s Six Hours of The Glen is the first race in the U.S. since May 1 for Corvette Racing and the rest of the field of competitors in the new GT Daytona (GTD) PRO category. Through five races, Garcia and Taylor stand second in Drivers points, as does Chevrolet in the Manufacturers standings on the strength of a class victory at the Mobil 1 Twelve Hours of Sebring.

The No. 3 Corvette also arrives at The Glen leading GTD PRO in the Michelin Endurance Cup a championship made up of the WeatherTech Championship’s four long-distance races. Given recent success at The Glen, there’s a better than average chance that advantage remains going into the weekend.

Corvette Racing has three victories at Watkins Glen since 2014 including two last year.
Garcia and Taylor won in the GT Le Mans (GTLM) category in last year’s Sahlen’s Six Hours as well as the WeatherTech 240 sprint a race a week later.
Garcia is one of nine drivers to win more than once in the Sahlen’s Six Hours and has five podium finishes in his last five races at The Glen, while Taylor won for the first time in the event a year ago.

Chevrolet has a strong history of success in the race with 18 victories second among active manufacturers.
The GTD PRO Corvette differs in several ways from the C8.R that ran at Watkins Glen in 2021. Chief among the differences are additional weight, restricted power and customer Michelin tires that are mandated for all GTD entries as opposed to Michelins specifically designed for the C8.R in GTLM trim.

Chevrolet Motorsports Display On-Site at The Glen

In addition to the many series and events on the racetrack at Watkins Glen, fans will have plenty to see and experience from Chevrolet.
The Chevrolet Motorsports Display will be full of Chevy vehicles that spectators can learn more about throughout the weekend.
The Chevrolet Motorsports Display opens at 8 a.m. Friday through Sunday and is located in the Fan Midway at Watkins Glen International. Numerous Chevrolet vehicles and other highlights include:

• The 2023 Corvette Z06 convertible
• Additional Chevrolet products such as Blazer RS, Silverado ZR2, Camaro 2SS 1LE and Colorado ZR2
• A Corvette Racing C8.R showcar and LT6.R engine
• An opportunity to receive a 2022 Team Chevy t-shirt

Fans should also be on the lookout for an additional Corvette on the racetrack. A Corvette Stingray will serve as Official Pace Car for the two-hour Tioga Downs Casino race for the IMSA Michelin Pilot Challenge starting at 3:45 p.m. ET on Saturday.

The Sahlen’s Six Hours of The Glen is scheduled for 10:40 a.m. ET on Sunday, June 26.
The race will stream live on Peacock with USA’s live television coverage beginning at 2 p.m. ETIMSA Radio will air all on-track sessions beginning at IMSA.com along with XM 207 and SiriusXM Online 992.

ANTONIO GARCIA, NO. 3 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“I really, really like this race. I enjoy the track a lot. I believe it was my very first race in America in GRAND-AM. We’ve generally been strong there. Being a six-hour race, there always is something going on. It might be a super-hot race, there may be rainstorms, you never know what’s a race at Watkins Glen is going to be like. That’s why experience is a good thing to have there.
I think I’ve run in every different condition there, so I’m looking forward to going back in this new class and see how this spec of the C8.R fits in there.”

JORDAN TAYLOR, NO. 3 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Winning last year’s race was a big deal. It was always on my dad’s bucket list of races to win as a driver. I think it was the only endurance race that he hadn’t won. He won Daytona, Sebring, Petit Le Mans and Le Mans, so the one he always talked about was the Six Hours.
The same was happening for me. I had gone all these years without winning it. I finished second a couple of times, I think, and it was always something little. To finally have everything click and work out was pretty special. It really kicked off our season last year with a good run of success.”

“Watkins Glen was always a cool race for me from obviously watching sports car racing but also being a fan of motorsport. It was one of the few natural-terrain road courses that Formula One used in America. Seeing old footage of Formula One cars around there and still having the classic blue guardrails to pay homage to the history is pretty special. To win at those types of tracks is really nice.”

06/21/22 09:36 PM DCT Service Tranny message and a CEL by teamzr1
2020-2022 Corvette models may have a Service Transmission message on the Driver Information Center (DIC), an illuminated Check Engine MIL and a squealing sound immediately after starting the engine. DTC P0700 (Transmission Control Module Requested Malfunction Indicator Lamp Illumination) may be stored in the Engine Control Module (ECM) and DTC P0606 (Control Module Processor Performance) or P0607 (Control Module Performance) may be stored in history in the Transmission Control Module (TCM).

Other P codes may also be set.
This condition will be present on vehicle start up only and not when the vehicle is in motion.
The DIC transmission message and possible squealing sound are default actions of the DTC as the TCM is in a defaulted state and may not be controlling line pressure, resulting in the transmission operating a maximum line pressure.

DTC P0700 is an informational DTC. Do not replace the control module if DTC P0700 is set.

If DTC P0606 or P0607 is set as a current DTC in the TCM, without other DTCs set, follow the published diagnostics in the appropriate Service Information.
The condition should be resolved by allowing the vehicle to go through a complete sleep cycle (i.e., 15 minutes).

Explain to customers that they can complete this process if they experience the condition again before a correction is available.

If DTC P0606 or P0607 is set as a history DTC in the TCM with other P codes (e.g., P07E5 or P07E6), the other codes are a byproduct of the controller state.
Do not replace the TCM for P0606/P0607 when other P codes are present or when DTCs P0606/P0607 are in history.

If DTCs P0606/P0607 are in history, clear the codes and test drive the vehicle to make sure the DTCs do not return.
If the DTCs do not set again, return the vehicle to the customer.

Permanent repair information will be released when available.

06/18/22 09:42 PM Warnings related to C8 Z06 wheels by teamzr1
Due to hub thickness differences when buying a C8 Z06 or with Z07 and use of Carbon Fiber wheels is the stud lengths are
different and must change the studs to proper length depending on if using CF wheels or other types

And another warning about mounting CF wheels in cold weather

Refer to owner's manual that points out both of these warnings





06/15/22 11:06 PM Total Loss of C7 Z06 Drag Racing by teamzr1
Bad day for this owner of this 2017 Long Beach Red C7 Z06 who was racing at a drag strip

The Corvette had just 14,000 miles and no power mods, only cooling mods and suspension mods for track duty. He had used it for 20 track days over the past 11 months, describing his ownership experience as “just like an ex-girlfriend. It was great while it lasted, but there were signs she was a psycho from the beginning.”

During what would turn out to be his final track session with the car at Laguna Seca in late May, the owner who ultimately posted in-depth about his misfortunes on Corvette Forum, where he’s known as dllhg says he first noticed smoke in the cabin seven laps into his first session, with the temperature outside just 65 degrees.

The smoke escalated very quickly, and dllhg writes that he began to search immediately for a good place to pull over, deciding on a spot between turn 5 and turn 6 in “a nice dirt patch.”

It was so smoky inside the cabin that he says he had a hard time breathing.
After immediately undoing his six-point harness, he couldn’t get the door to open and had to use the manual lever. Upon exiting the vehicle, he spotted small flames dropping below the car in the right rear.

The track tow arrived in minutes and the driver extinguished the small fire probably five or six times, dllhg says, but then suddenly the cabin erupted into flames.

“I yell[ed] at him to pull back and that the car was gone at this point,” dllhg says. “I didn’t want anyone getting hurt – had ¾ tank of fuel.”

As you can see in the accompanying photos, the car soon turned into a healthy ball of fire.
“Fire dept arrived very quickly,” he posted. “The fire started in the right rear and moved over to the left rear when it really got going.”

He describes it as “a very surreal experience” watching the car he had invested so much time and money on “just burn to the ground.”
But he says he’s “grateful to be okay,” though his lungs were sore for a few days. Still, he kept telling the firefighters “it’s just a car – replaceable

As for the cause of the fire, dllhg says the firefighters don’t think it was fuel nor a bad aftermarket battery. He believes it might be related to the trans line in the right rear, as 2017 and older cars have a small flex section with no heat shielding (2018 and above do have heat shielding, by the way.)
“Thanks for the afterthought, GM,” he jokes.

“Lots of heat up in there from exhaust, maybe the line got brittle and finally sprung a leak?
Differential seems less likely. On the left side was a trans cooler.
I’m guessing once the fire got bigger it jumped over there, won’t ever know for certain.”

06/15/22 02:31 PM GM adds to 2023 MY a DCT Filter Monitor by teamzr1
Chevy has now added an entry to the Oil and Fluid Life display under the maintenance tab for the DCT’s canister filter which shows the amount of life remaining.

The 2023 Corvette Owner’s Manual recommended that owners replace the filter at 7,500 miles and then again when the odometer turns 22,500 miles. However, if the percentage of life is less than 10%, the manual recommends changing the DCT canister filter immediately as performance issues may result.

Here is what the Owner’s Manual states:

Transmission Filter Life: Displays an estimate of the filter’s remaining useful life.
If REMAINING FILTER LIFE 99% is displayed, that means 99% of the current filter life remains.

When the remaining filter life is low, the REPLACE TRANSMISSION FILTER SOON message will appear on the display.
The external canister filter should be replaced as soon as possible.
See Dual Clutch Transmission Fluid Life System (page 249).
In addition to the Transmission Filter Life system monitoring the filter life, additional maintenance is recommended in the Maintenance Schedule.
See Maintenance Schedule (page 306).

Unknown at this time is will GM do a software update going back to past C8 years to also have this DCT filter monitor

06/11/22 10:16 PM Total Moron C8 Driver by teamzr1
Rummy driver depicted in the video below. In what appears to be a failed attempt at a power slide or drifting the mid-engined rear-wheel-drive sports car, the owner lost control and ended up crashing into the greenery.

The video was originally posted on Instagram by a user who witnessed it live from his car. Tyler stated that when the police arrived, the driver “blew a .3″ blood alcohol content and was issued a DUI.

The white Corvette Convertible can be seen accelerating hard, with the tires squealing as it approaches the end of the tarmac. The driver turns the wheel but the vehicle slightly under-steers and the rest is, well, just painful to watch.
The mid-engine model hits the gravel bump with its front end, making a loud noise.

The force of the crash most likely resulted in breaking the front bumper and damaging the underside of the car.

The guy who shot the video has also posted a picture of the aftermath, showing the Corvette being towed out of the ditch.
Thankfully, there were no serious injuries involved, but we are sure that the driver of the C8 was pretty shaken up by this experience.

We don’t know the extent of the damage sustained by the C8, but this kind of incidents usually doesn’t come cheap.
Besides replacing the front bumper, the Corvette could have issues with the front suspension, front wheels, and airbag (if deployed), increasing the bill.
In any case, the driver will think twice before doing stunts behind the wheel of expensive vehicles.






06/09/22 04:36 PM 2023 Caddy GTP Racer by teamzr1

Cadillac Racing today has pulled back the covers on its new prototype for 2023 that will replace the championship-winning Cadillac DPi-V.R in IMSA’s WeatherTech SportsCar Championship.

Dubbed the “Project GTP Hypercar,” a number of similarities and differences to the current DPi can be found with the car that will campaign by Chip Ganassi Racing and Action Express in IMSA’s GTP class starting at January’s Rolex 24 At Daytona.

Just like the current DPi-V.R, the GTP is built by Dallara in Italy. It also features a brand-new double-overhead cam 5.5-liter naturally aspirated V8, which is the same displacement as the motors found in the DPi-V.R. The engines are expected to be built within the GM Racing family, which would be a change from the DPi-V.R which uses Earnhardt Childress Racing to prepare and support its powerplants.

Together with IMSA’s spec energy recovery system connected to the 5.5-liter V8, the 680hp GTP will serve as Cadillac’s first hybrid prototype.
Compared to the DPi-V.R which bears a strong resemblance to the stock Dallara P217 LMP2 chassis it’s based upon, the new GTP car makes a strong departure with its styling as heavy Cadillac road car cues are featured at the front of the prototype.

Cadillac Design, Cadillac Racing and its selected chassis partner Dallara have co-developed the shape of the vehicle to incorporate identifiable brand characteristics such as vertical lighting and ‘floating blades’.
“Cadillac will be competing again on the world racing stage, and we are all thrilled to return to Le Mans after 20 years,” said Rory Harvey, Vice President of Global Cadillac.

“By competing in both the 2023 IMSA and WEC championships, Cadillac Racing has the opportunity to demonstrate its capability, craftsmanship and technology.”
Chris Mikalauskas, Cadillac’s lead exterior creative designer, added:
“The Project GTP Hypercar is a unique convergence of form and function and showcases Cadillac’s future performance aesthetic.
“We have plenty more to come, from the upcoming race car to amazing production vehicles.”

Cadillac announced its LMDh program in August 2021 when it named Action Express Racing and Chip Ganassi Racing as its partner teams for the project.
It issued a teaser image of the car’s design in February, with that depiction of the front end bearing resemblance to part of the full-car render issued on Wednesday.
The 5.5-liter dual overhead camshaft V8 engine will be “all-new” according to Cadillac and follows on from the same displacement V8 found in the company’s DPi prototype for the WeatherTech Championship.

Cadillac is currently targeting a “summer” rollout, after previously hoping to conduct the car’s first shakedown in the spring.
The next two months are set to be a hive of activity in terms of prototype testing, with Ferrari planning to roll out its hybrid LMH car in July and BMW also getting closer to the initial shakedown of its LMDh machine, which like the Cadillac is based on a Dallara.

“Competing for the overall win at Le Mans with an iconic American brand like Cadillac is an honor,” said GM sports car racing program manager Laura Wontrop Klauser.
“The entire team is excited to continue building Cadillac’s racing legacy by competing against the very best internationally and in the world’s toughest race.”

This year, C8.R Corvette has split its racing strategy, running one C8.R in the IMSA WeatherTech SportsCar Championship, and one in the WEC.
Tandy and Milner currently lie fourth in the latter's GTE Pro class after second in the Sebring 1000-mile race and fourth in the six-hour race at Spa-Francorchamps

Despite Le Mans being worth double points and a poor finish or even worse, a DNF likely to end their title quest, both drivers are prepared to risk running flat-out in order to achieve victory in the WEC’s marquee event.
“Running WEC doesn’t change anything for me in terms of preparation,” said Milner, who won Le Mans with a Corvette C6.R in 2011 and with a C7.R in 2015" (the team’s last win at the track).

No matter what, we finish the race, and we finish as strongly as we can. We race hard to the end no matter what our position is.
Now that we have some concerns for points in the full WEC championship, we’ll race with that in mind.
But it doesn’t change the fact that winning Le Mans would be the crown jewel for this season.

This is how we’ve always raced, and it won’t change. It just means that the points at the end of the weekend will mean a little bit more.

Tandy, who won the race overall with Porsche back in 2015, declared: “Le Mans is Le Mans. It’s always been its own event.
Now it’s a part of our championship and a double-points one at that, so it takes on extra significance now for us this year, at least on the #64 side.

“One of the reasons we entered the [full] WEC is that it gives us more preparation, information and experience of the series’ rules and regulations. It’s things like pit stop sequences, maximizing strategy information and bits and pieces that are different from series to series.
"We have more information about what we can do better going into Le Mans. We’re coming into Le Mans with the best level of preparation that Corvette Racing has ever had.

“It’ll be the first time that we’ll run the low-drag aero kit, so the car will be a little different from what we were used to at Spa.
The other good thing is that we have last year’s experience and data to look back on. We’re not coming into this with a brand-new car.”

Milner and Tandy will be joined in the #64 C8.R by Alexander Sims, while the sister #63 car will be driven by the usual IMSA endurance race line-up of Antonio Garcia, Jordan Taylor and Nicky Catsburg.

With IMSA no longer running the GTLM class (a WEC GTE Pro equivalent) but instead GTD Pro (GT3 cars), it means this trio has to re-adapt to cars with Corvette-specific tires from Michelin, no anti-lock braking system and slightly more power. However, two of them at least aren’t expecting this to be an issue.
Said Garcia: “It would be way different if we were running the GTD Pro spec. We are going back to our regular GTE setup in the C8.R, and I’m looking forward to that. Part of it won’t be ideal as Jordan, Nicky and myself will need to re-adapt to that car a little bit.

"Having the #64 car in the WEC will help the whole team, though. We will need to get up to speed at the start, and maybe the #64 car will start some development early on.
"We’ve done this race so many times and have raced the GTE spec so many years that it won’t take much to get on the pace. To be honest, it is more difficult to drive the IMSA [GTD Pro] car compared to what we have driven for the last 15 years!”

Catsburg added: “The last time I drove a car without ABS was Petit Le Mans in the Corvette.
That’s a bit of a handicap but we’re all more than capable to make that adjustment and be ready for it.
I’ve always been going back and forth between GTE and GT3 whenever I would come race in the States, last year…
“I honestly prefer a car without ABS. We’re all in the same boat, and we can all do this, for sure.”

Taylor, who completed some tire testing in a GTE-spec Corvette in March, sounded a more cautionary note, stating:
I still think it’s going to be a big adjustment for us going back to that, especially with it being such a tight schedule on [Le Mans] race week.

There is such limited time to get three guys through the car with such a long lap and adding in the car development we want to do.
Hopefully we can hit the ground running and get comfortable right off the bat to get into development.”

06/04/22 02:36 AM What Exactly is Top Tier Gas ? by teamzr1
Some of the best ways to help enhance fuel economy are through proper maintenance and good driving habits.
For example, replacing the engine air filter at the recommended maintenance intervals, maintaining the correct tire inflation pressures and removing any extra equipment from the vehicle, such as bike racks, can help in reducing fuel consumption.
At the same time, driving less aggressively and anticipating stops can also help

There are other items that customers should consider as well as to optimize their vehicle’s fuel economy.
Here are a few things to share with customers regarding optimizing vehicle performance.

TOP TIERTM Gasoline

Properly maintained engines can provide optimal fuel economy and performance. TOP TIER gasoline was developed in 2004 when a group of automakers, including General Motors, BMW, Honda, Toyota, Volkswagen, Audi and Mercedes-Benz, recognized the need for a higher detergency gasoline than that required by U.S. regulation.
TOP TIER Detergent Gasoline is the premier standard for gasoline performance, with a higher detergency standard than the U.S. Environmental Protection Agency (EPA) and Canadian General Standards Board (CGSB) minimum requirement.
The added detergents can result in a lower amount of intake valve deposits that can negatively affect fuel economy, emissions, and performance.

Avoid lower quality gasoline that can leave deposits on critical engine parts, reducing engine performance.
TOP TIER fuels are preferable when and where available.
Many fueling stations selling TOP TIER licensed brands prominently display the TOP TIER logo on the pump, pump handle, canopy or in a station window.

TIP:

The Top Tier fuel designation should not be confused with higher octane (plus/premium grade fuel) commonly sold at most gas stations.
Plus and premium fuels are required in some GM high-performance vehicles. However, they do not necessarily represent the higher detergency that is present in available TOP TIER Detergent Gasolines.
For high-performance vehicles that require premium fuel (91 octane or higher), fuels of at least this octane must be used. Using lower octane fuel may result in reduced performance, knocking, and/or permanent engine damage that is not covered under the terms of the New Vehicle Limited Warranty.
Using higher octane fuels in a vehicle that only requires regular unleaded fuel will not increase performance or improve gas mileage.
Only use the octane-rated fuel recommended, as specified in the vehicle’s Owner’s Manual.

Additional gasoline brands are added to the TOP TIER list as they meet the standards.
For a list of TOP TIER Detergent Gasoline retailers, visit toptiergas.com.

Alternate Fuels

A recent idea to improve fuel economy is to blend either kerosene or diesel fuel into gasoline. Both kerosene and diesel fuel are distillate fuels meant for use in compression ignition engines, not spark ignition engines. They have very low octane and, since they are heavier (higher density) than gasoline, they will cause heavy engine deposits, degradation of engine oil and very poor drivability.
If kerosene or diesel fuel is put into a gasoline engine vehicle, any performance conditions, drivability concerns or damage to the engine will not be covered by the New Vehicle Limited Warranty.

Fuel Injector Cleaning

Fuel injector cleaning is recommended only when performed as directed in Service Information diagnostic procedures. However, to address the variation in fuel quality in different areas of the country, the only preventative maintenance currently endorsed by GM regarding its gasoline engine fuel systems is the use of GM Fuel System Treatment PLUS added to a tank of fuel at each oil change.
The fuel additive is to help with the prevention and removal of deposits from spark-ignited engines, particularly from the intake valves, fuel injectors, and the combustion chamber.

Driving Habits

Many driving habits as well as driving conditions affect fuel consumption, such as aggressive driving, altitude, ambient temperature and traffic.
While driving, slow down and drive smoothly. Efficient driving include avoiding quick/full-throttle acceleration from a standstill at stop lights and high cruising speeds on the interstates.

While the optimum MPG or L/100 km for highway cruising speed varies from vehicle to vehicle, faster is almost always worse. If the vehicle is equipped with a Driver Information Center that displays Instant Fuel Economy, select that display and vary the vehicle’s cruising speed while on the highway.
The display will change continuously with uphill and downhill sections, but you should quickly be able to identify on level ground the speed range that the vehicle performs best in.
In addition, before a trip, avoid extended idling when starting the vehicle.

There is no need to idle the engine until it reaches full operating temperature.
Extended idling time wastes fuel and has a negative impact on fuel economy.
When using the Remote Start feature (if equipped) keep the idling time to a minimum.
Starting the car on a very cold day and leaving immediately may actually cause the engine to consume more gas.
Warming it up and thinning the oil for a few minutes can actually help improve mileage.

05/31/22 10:19 PM This Saturday’s IMSA Chevrolet Sports Car Classic Detroit Grand Prix by teamzr1
Note also do not forget this Saturday’s IMSA Chevrolet Sports Car Classic Detroit Grand Prix

The Corvette Racing band is back together for the first time in three months with the team channeling all its efforts into another shot at a class victory at this year’s 24 Hours of Le Mans.
Two of the familiar yellow Corvettes are part of a seven-car entry in the GTE Pro category for factory and factory-supported teams.
This will be the second time at Le Mans for the mid-engine Chevrolet Corvette C8.R after a runner-up class finish in its debut last August.
The program is going for its ninth class victory at the French endurance classic.

This year’s race is back in its traditional June spot with the race set for June 11-12. The biggest change from last year’s event is that all public-facing events are back including scrutineering in downtown Le Mans, pit walks and autograph sessions and the Friday drivers’ parade.

Before practice and qualifying gets under way, though, first comes eight hours of track time Sunday during the annual Le Mans Test Day.
It’s the one opportunity for the 62 cars entered in the race to get much-needed track time ahead of Wednesday’s first practice and qualifying sessions.
Time is critical given the unique nature of the circuit 8.47 miles of asphalt featuring a mix of permanent racetrack and public roads through the French countryside.

The Corvette Racing lineup in each of the two C8.Rs remains the same as a year ago. Antonio Garcia, Jordan Taylor and Nicky Catsburg primarily competing in the IMSA WeatherTech SportsCar Championship will team in the No. 63 Mobil 1/SiriusXM Corvette and hope to improve on their second-place showing from a year ago. Already, the trio has a blue-riband victory together in at the Mobil 1 Twelve Hours of Sebring in a GT Daytona (GTD) PRO version of the C8.R.

On the other side of the garage is the No. 64 Mobil 1/SiriusXM C8.R of Tommy Milner, Nick Tandy and Alexander Sims. Their entry is a full-time one in the FIA World Endurance Championship a first for Corvette Racing. It’s already been a successful run for Milner and Tandy with a runner-up finish in the Sebring 1,000 Miles.

The duo stand third in the GTE Drivers World Championship with Le Mans being a double-points race.
That makes it even more important for the No. 64 Corvette to show well at Le Mans and keep the other manufacturers off the top step of the podium as well.

The plan of having a Corvette full-time in WEC was focused around optimizing the team’s chances at Le Mans. Corvette Racing’s last win at Le Mans came in 2015, although the team has been agonizingly close to getting its ninth win there since with a second- and third-place showing in the years since.

The WEC Corvette has given the entire Corvette Racing team much-needed insight and data on a wide variety of items that will be key at Le Mans.
Things like pit stop procedures, tire selection and performance, and racing rules in a variety of scenarios make this the most prepared that Corvette Racing has been for Le Mans in what will be its 22nd appearance in the race.

One of the most key benefits is that the No. 64 Corvette can focus more on race setup and development on the Test Day while the three No. 63 drivers can get used to the GTE version of the Corvette, which features more power, no ABS system and Michelin tires specifically designed for the C8.R. In IMSA, the GTD PRO Corvette runs on a common Michelin tire that is available to all teams.

Corvette Racing will contest the 24 Hours of Le Mans on June 11-12 with the green flag set for 4 p.m. CET and 10 a.m. ET. MotorTrend TV will air the race live with the MotorTrend App adding coverage of official practices and qualifying on June 8-9. Live audio coverage will be available from Radio Le Mans starting with Sunday’s Test Day.

ANTONIO GARCIA, NO. 63 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Le Mans shouldn’t be too different this year. It would be way different if we were running the GTD PRO spec. We are going back to our regular GTE setup in the C8.R, and I’m looking forward to that. Part of it won’t be ideal as Jordan, Nicky and myself will need to readapt to that car a little bit.
Having the 64 car in the WEC will help the whole team, though. We will need to get up to speed at the start and maybe the 64 car will start some development early on.
We’ve done this race so many times and have raced the GTE spec so many years that it won’t take much to get on the pace.
To be honest, it is more difficult to drive the IMSA car compared to what we have driven for the last 15 years!

“It’s been too long since I have won Le Mans. We’ve been on the podium several times and could have won all those. That also tells you that you’re one of the most angry people because coming in P2 or P3 is not ideal, especially if you have a chance to win. In these races, only one car can win. If you give it everything you had and you didn’t win, then someone did it just a tiny bit better than you.

Last year, I think we had everything lined up. The pace was great but we didn’t have enough to gain those 20, 30 and 40 seconds to get ahead. It seems like very little over a race distance but we know that’s how Le Mans works. Every second you lose is very difficult and gaining that back in GTE Pro is a tough task. We need to be the ones leading and let the rest catch us. I think that is what works best at Le Mans.”

JORDAN TAYLOR, NO. 63 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“I got to do some tire testing with Nick (Tandy) a couple of days after Sebring in the GTE car. But I still think it’s going to be a big adjustment for us going back to that, especially with it being such a tight schedule on the race week. There is such limited time to get three guys through the car with such a long lap and adding in the car development we want to do.
Hopefully we can hit the ground running and get comfortable right off the bat to get into development. So it will be a little bit more of a challenge but having the 64 guys over there all year in WEC takes away some development time, so hopefully that will help us when we get there.

“It’s frustrating to look back at last year to know we did nothing majorly wrong, didn’t make any mistakes and still came up short. That part is frustrating but I think we can rely on the fact that we did a perfect race. We can have that confidence going back this time. We’ve developed the car further than where it was last year for the first time with the C8.R.

We did miss a lot of practice on the 63 side throughout the beginning of the week so I think we were behind the eight-ball a little bit compared to the other car once the race started. So we maybe were missing a little bit of performance on our own. But going into this year with what we learned last year and the confidence of a good race we had, we know we are going back with a stronger car and good position.”

NICKY CATSBURG, NO. 63 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Having now done Le Mans with Corvette Racing, I can go into the weekend a little more relaxed.
I know how the team operates and even the most basic things where I stay and where I sleep, how processes work.
From that point of view, I will be a little more relaxed going into the event. In terms of race prep and how we are going to execute, I don’t think there is anything different than the previous year other than the fact that everyone has a little more experience with the C8.R at Le Mans and in the WEC. I feel we should be pretty well prepared.

“There is some mojo from our win at Sebring. The car felt really good last year at Le Mans. Maybe Ferrari had a little bit of the upper hand, but I feel like this year we should be in a better position. The only downside is the 63 car guys have driven the car less in GTE spec.

The last time I drove a car without ABS was Petit Le Mans in the Corvette. That’s a bit of a handicap but we’re all more than capable to make that adjustment and be ready for it. I’ve always been going back and forth between GTE and GT3 whenever I would come race in the States last year.

You’d always have to take some time to adjust to the car. Really the biggest difference is the ABS, and I honestly prefer a car without ABS. We’re all in the same boat and we can all do this, for sure. Le Mans is one of my favorite events of the year. The track obviously is fantastic and abnormal in that way. I really, really can’t wait!”

TOMMY MILNER, NO. 64 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Winning obviously is the goal. I feel like every time we’ve been to Le Mans, we’ve done all our due diligence beforehand in testing to show up as competitive as we can be. Having some experience this year in WEC and data running on this tire will be helpful for the entire team. From that perspective, this will prove to be very helpful. We’re going to be as prepared for Le Mans as we can be.

We saw last year that the car already was fast and competitive. Hopefully with the potential for more data for the ACO and FIA to compare our cars, the balance is as good as it can be for a good GTE Pro race for 24 hours. Based on the pace we’ve show in the WEC and last year at Le Mans, I think we have a great Corvette.

“Running WEC doesn’t change anything for me in terms of preparation. No matter what, we finish the race and we finish as strongly as we can. It hasn’t been in the past where if we can’t win then we park it. It’s not our mantra at Corvette Racing. We race hard to the end no matter what our position is. Now that we have some concerns for points in the full WEC championship, we’ll race with that in mind.

But it doesn’t change the fact that winning Le Mans would be the crown jewel for this season. This is how we’ve always raced and it won’t change. It just means that the points at the end of the weekend will mean a little bit more.”

NICK TANDY, NO. 64 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“Le Mans is Le Mans. It’s always been its own event. Now it’s a part of our championship and a double-points one at that. So it takes on extra significance now for us this year, at least on the 64 side. One of the reasons we entered the WEC is that it gives us more preparation, information and experience of the series’ rules and regulations.
It’s things like pit stop sequences, maximizing strategy information and bits and pieces that are different from series to series. We have more information about what we can do better going into Le Mans. We’re coming into Le Mans with the best level of preparation that Corvette Racing has ever had.

“Certainly from the crew and engineering side, everyone on our side is ready to go with what we’ve been working on for the last six months effectively. When the track goes green for the Test Day, we’ll be ready to go and crack on with our performance work. When we’ve been there before as a single event, it does take a little bit of time to get into the differences where the guys are running the car being on the pit wall, people worried about making regulation errors in the pitlane or things like this that we aren’t used to. From that point of view, this is one of the key points of running the full championship.

The more experience you have, the better it is. Past that, everyone on the 63 side have all been here and done this many times. It’ll be the first time that we’ll run the low-drag aero kit so the car will be a little different than what we were used to at Spa. The other good thing is that we have last year’s experience and data to look back on. We’re not coming into this with a brand new car.”

ALEXANDER SIMS, NO. 64 MOBIL 1/SiriusXM CHEVROLET CORVETTE C8.R:

“The fact that this will be a bit more familiar to me will be a nice thing. The biggest factor me is the length of time that it’s been since I was last in the car at Petit Le Mans. That likely will be the biggest challenge to get on top off… just to get back in the swing of things. I’m fortunate that I am doing some GT racing at the Nürburgring this year, so I’ll have driven a GT car but not the Corvette. That’s really the main thing getting back into the swing of driving the C8.R.
To be fair, the last time at Le Mans and by the time the race came around, I felt fully in tune and that’s the aim again this year.

“There is plenty of track time available but I need to make sure I do my homework and work very hard to get up to the required level that I expect from myself and that the team deserves from me. That will be the main point of focus for me early in the week. I go back there with reference points from the car from last year in terms of my driving.
I kind of know what to expect in terms of how the car should feel, driving lines and all of those things that I don’t have to learn again.
It’s a slightly more manageable task than last year.”

05/26/22 07:44 PM GM Vehicles Get Hacked Again by teamzr1
May 2022 - General Motors itself suffered a hack that exposed a significant amount of sensitive personal information on car owners names, addresses, phone numbers, locations, car mileage, and maintenance history.

The Detroit-based automaker revealed details of the incident in a breach disclosure ( see attached PDF below) filed with the California Attorney General’s Office not until May 16.
The disclosure explains that malicious login activity was detected on an unspecified number of GM online user accounts between April 11 and 29.

Further investigation revealed that the company had also been hit with a credential stuffing attack, which saw hackers infiltrate user accounts to steal customer reward points, which they then redeemed for gift cards. Credential stuffing is a rudimentary type of cyberattack that involves using lists of previously compromised login credentials to hack into online accounts. Such lists can be purchased with relative ease on the dark web.

We took swift action in response to the suspicious activity by suspending gift card redemption and notifying affected customers of these issues.
We also took steps to require those customers to reset their passwords at their next log in, and we reported this incident to law enforcement,” the company says. Customers whose reward points had been abused were subsequently replenished with new reward points, the company added.

In addition to the reward points theft, the incident also exposed a significant amount of user information.
GM’s breach notification lays out a full list of the information that may have been compromised by the hackers:

• first and last name
• personal email address
• home address
• username
• phone number
• last known and saved favorite location
• OnStar package (if applicable)
• family members’ avatars and photos
• profile picture
• search and destination information
• reward card activity
• fraudulently redeemed reward points

It’s unclear exactly how many customers were affected by this breach, though we know it’s more than 500 in California alone. California law requires that companies file public breach notifications to the OAG in cases where the number of state residents affected by the incident until is greater than 500 people.
But this is nothing new as GM and other nameplates have been hacked over and over again over last 10 years

In GM’s vehicles is no better as Onstar which is a spy to vehicles & their owners also opened the vehicles network to countless crooks

A pair of security researchers showed they could hack a Jeep over the Internet earlier this summer to hijack its brakes and transmission, the impact was swift and explosive: Chrysler issued a software fix before the research was even made public.
The National Highway Traffic and Safety Administration launched an investigation. Within days Chrysler issued a 1.4 million vehicle recall.

But when another group of researchers quietly pulled off that same automotive magic trick five years earlier, their work was answered with exactly none of those reactions.
That’s in part because the prior group of car hackers, researchers at the University of California at San Diego and the University of Washington, chose not to publicly name the make and model of the vehicle they tested, which has since been revealed to be General Motors’ 2009 Chevy Impala.
They also discreetly shared their exploit code only with GM itself rather than publish it.

The result, WIRED has learned, is that GM took nearly five years to fully protect its vehicles from the hacking technique, which the researchers privately disclosed to the auto giant and to the National Highway Traffic Safety Administration in the spring of 2010.
For nearly half a decade, millions of GM cars and trucks were vulnerable to that privately known attack, a remote exploit that targeted its OnStar dashboard computer and was capable of everything from tracking vehicles to engaging their brakes at high speed to disabling brakes altogether.

“We basically had complete control of the car except the steering,” says Karl Koscher, one of the security researchers who helped to develop the attack. “Certainly it would have been better if it had been patched sooner.”

But the researchers argue that GM’s years-long failure to fully protect its vehicles from that attack doesn’t reflect on GM’s negligence, so much as a lack of security preparation in the entire industry of Internet-connected cars.
Automakers five years ago simply weren’t equipped to fix hackable bugs in their vehicles’ software, the way that Microsoft and Google have long fixed bugs within weeks or even hours after they are disclosed to them. And many of those companies may not be much better prepared today.

“They just didn’t have the capabilities we take for granted in the desktop and server world,” says Stefan Savage, the UCSD professor who led one of the two university teams who worked together to hack the Impala. “It’s kind of sad that the whole industry was not in a place to deal with this at the time, and that today, five years later, there still isn’t a universal incident response and update system that exists.”

In fact, GM tells WIRED that it has since developed the ability to push so-called “over-the-air” updates to its vehicles. The company eventually used that technique to patch the software in its OnStar computers via the same cellular Internet connection the UCSD and UW researchers exploited to hack the Impala. Starting in November of 2014, through the first months of 2015, the company says it silently pushed out a software update over its Verizon network to millions of vehicle with the vulnerable Generation 8 OnStar computer.

Aside from the strangely delayed timing of that patch, even the existence of any cellular update feature comes as a surprise to the UCSD and UW researchers. They had believed that the OnStar computers could be patched only by driving them one-by-one to a dealership, a cumbersome and expensive fix that would have likely required a recall.

GM chief product cybersecurity officer Jeff Massimilla hints to WIRED that performing the cellular update on five-year-old OnStar computers required some sort of clever hack, though he refused to share details.
"We provided a software update over the air that allowed us to remediate the vulnerability,” Massimilla writes in an email. "We were able to find a way to deliver over-the-air updates on a system that was not necessarily designed to do so.”

But Massimilla also admits that GM took so long to fully protect its vehicles because it simply wasn’t ready in 2010 to deal with the threat of car hackers. He contrasts that response to GM’s cybersecurity practices today, such as issuing a fix in just two days when it was alerted to a flaw in its iOS OnStar app in July. “The auto industry as a whole, like many other industries, is focused on applying the appropriate emphasis on cybersecurity,” he writes. “Five years ago, the organization was not structured optimally to fully address the concern. Today, that’s no longer the case.”

A Brilliant Hack Lullaby Ahead of Its Time

GM’s glacial response is partly a result of just how far ahead of its time the UCSD and UW researchers’ OnStar attack was.
Their technique, described in a pair of papers in 2010 and 2011, represented a brilliant and unprecedented chain of hacker attacks integrated into a single exploit.
The intrusion technique began with a phone call to the Impala’s OnStar computer. Because Verizon’s voice network coverage was more reliable than its data network, the OnStar computers were programmed to establish a connection to any computer that played a certain series of audio tones, like an old-fashioned modem. UW’s Koscher reverse engineered that audio protocol and created an mp3 file that could trigger a vulnerability in the computer known as a “buffer overflow.”

From that initial audio attack, the attackers could pivot to take control of the OnStar computer’s higher-bandwidth data connection and finally penetrate the car’s CAN bus, the collection of networked computers inside a vehicle that control everything from its windshield wipers to its brakes and transmission.
Put simply, “you play this song to it, and the car’s taken over,” says UCSD’s Savage.

How GM Tried (And Failed) to Fix It: A Timeline

GM did, in fact, make real efforts between 2010 and late 2014 to shield its vehicles from that attack method, and patched the flaws it used in later versions of OnStar. But until the surreptitious over-the-air patch it finished rolling out this year, none of its security measures fully prevented the exploit in vehicles using the vulnerable eighth generation OnStar units.
Given that GM told the FCC it had two million Generation 9 Onstar computers deployed in 2011, former UCSD researcher Stephen Checkoway estimates that it had sold at least that many Generation 8 OnStar-enabled vehicles, too. “I would expect there were still several million vulnerable vehicles on the road,” Checkoway says.

Instead of updating the software on those Generation 8 OnStar units, GM first tried to block the attack on its cellular network. Sometime in 2011, it had Verizon put in a place a new measure on its wireless network to block data connections from OnStar computers to any server other than those approved as those belonging to GM.

But the researchers quickly found that a flaw existed in that fix, too. One in every 10 or 12 times that they restarted their Impala, its OnStar registered with the Verizon network in a way that somehow failed to prevent it from connecting to a malicious server, allowing their exploit to work again;

An attacker could have auto-dialed thousands of phone numbers to find and hack the fraction of vehicles in that unsafe mode. Even the researchers say they never fully understood why the Verizon network protection measure failed, though they say they warned GM about the problem within a few months of finding it.

GM claims that it responded by tweaking its network protection again, but even those secondary measures seem to have failed.
In 2012, the researchers were able to demonstrate their Impala hack for a PBS documentary despite Verizon’s and GM’s attempts to block it.
In late 2014, they demonstrated it yet again for a 60 Minutes episode that would air in February of 2015

05/25/22 02:11 PM C7 Corvettes Have Oil Pump Problems by teamzr1
GM TSB :

This bulletin applies to all 2014-2019 Chevrolet Corvettes and 2016-2019 Camaro vehicles equipped with a 6.2L LT1/LT4 engine.
You may find a DTC P06DD set in addition to no or low oil pressure.

The oil control valve may be stuck off, commanding high oil pressure (95 psi) and/or the oil pump face may be damaged.
The tensioner spring in the timing chain guide may be “short”, not fully seating into the guide pivot end.

Cycling the oil pump control valve will not cause changes in oil pump response.
A broken tensioner shoe may allow the spring to rub a hole in the oil pump.

Replace the timing chain tensioner guide.
If the oil pump face is damaged and/or worn, though, replace the oil pump.
Inspect engine bearings for damage that may have resulted in debris from the oil pump.

05/21/22 04:42 PM 133 in a 45 MPH Zone by teamzr1
A 21-year-old Corvette driver in Virginia has the dubious distinction of setting the fastest speed ever clocked by the Leesburg, Virginia Police Department.

Luke Jones of Leesburg came roaring past an officer going 88 mph ABOVE the legal limit in his blue 2007 Corvette coupe on Virginia Route 7 near Battlefield Parkway just before 5 p.m. on May 11.

The officer clocked the Corvette at a whopping 133 mph in a 45 mph zone which Leesburg police spokesman Michael Drogin says to his knowledge is the fastest speed a driver has ever been charged by the department.

We thought that it went without saying, however last week one of our officers had to remind a motorist that traveling 133 mph in a 45 mph zone is NEVER acceptable!
Generally, speeding is treated as a traffic offense, but Jones faces a mandatory appearance in court on a more serious misdemeanor criminal charge of reckless driving by speed.

The department said about the incident:

Remember, we all play a part in #TrafficSafety. PLEASE drive at the posted speed limit! #SlowDown


Maybe he was trying to join our Team ZR-1 Big Balls Gang ? smile
