11/24/22 06:36 PM Pay Nameplates Monthly Fees for Performance & Heating Up Your Ass by teamzr1
Mercedes has sparked controversy by introducing a $1,200 (£990) per-year subscription to unlock enhanced performance in its cars.

The yearly fee, which equates to $100 (£82) per month, increases horsepower and torque ('turning power') for its EQ series of battery-powered electric vehicles.
With the subscription, the time taken to accelerate from 0-60mph is reduced by up to a one second, depending on the model.

It comes shortly after BMW offered a subscription service to turn on heated seats in its cars, with various pricing options
The subscription, called Acceleration Increase, is 'coming soon' solely for US and Canada customers according to Mercedes

It's available for Mercedes EQE models (starting from $74,000) and Mercedes EQS models (starting from $102,000), debuted last year.
'The feeling of driving your Mercedes-EQ is a new experience every day, particularly its powerful, immediate acceleration,' the firm says on its website.

'Acceleration Increase boosts this performance even further electronically increasing the motor's output also increases the torque significantly, giving you a faster 0-to-60mph time. Acceleration power you can feel.'

Increased torque will let drivers accelerate their vehicle 'noticeably faster and more powerfully', according to the firm.

Fine-tuning of the electric motors increases the maximum motor output (in kilowatts) by 20 per cent to 24 per cent, depending on the original output.
The subscription doesn't add to the car's physical hardware, but instead triggers a software update that unlocks capability in its electric motors.
This capability has already been built-in, so drivers are having to pay to access motor performance that their vehicle is already capable of.
It also suggests Mercedes has intentionally limited performance on its vehicles to sell it as an optional extra.

A Mercedes spokesperson said that the ability to retrofit special vehicle functions after the initial purchase is 'a useful way for customers to flexibly adapt their car and use certain functions only when they are really needed or desired'.

We are constantly reviewing our offer concept in order to react as flexibly and quickly as possible to our customers' needs,' the spokesperson said.
'The goal is to generally offer on-demand features ex-factory as well as in the shop both as a subscription model and as a lifetime product.'
The spokesperson added that Mercedes will be offering Acceleration Increase as a permanent feature at a price that's yet to be determined.
The feature has gone down badly with car fans, with one calling it 'madness'.

Taking to Twitter, one user said: 'So Mercedes is slowing down their cars on PURPOSE so that you can pay a monthly subscription to go faster??
What the heck, we have to stop this madness.'
Another added: 'Late-stage capitalism is going to have people paying a monthly fee to improve the performance of a car they already bought.'
According to a tech enthusiast and anonymous CEO of an auto dealer group, there's a larger trend across industries to create subscriptions.
With subscriptions, companies can be guaranteed a constant revenue source rather than a one-off payment upon purchase.

Another example in the automobile industry is BMW, which generated significant controversy earlier this year when it introduced a subscription for heated seats.

BMW's service charge £15 per month to turn on heated front seats, as well as an additional £10 per month to switch on the heated steering wheel.

11/21/22 07:58 PM 2023 C8 Z06 Muffler Design by teamzr1
C8 Z06 has its own muffler design which is far different from what the Stingray has

11/20/22 07:37 PM C8 Z06 is a LOUD Bitch by teamzr1
Look at the 2023 Z06 Corvette with stock exhaust results at the bottom of this

The Dba even 5 feet back is way over federal law allows and even worse 2 feet away from exhaust tips

I know what loud is in designing my custom exhaust system for my C5 and then a lot of long term testing :

In testing, the sound as to DbC level is too high,
average inside the car with windows up is about 110 DB and as much as 128 DbC near the rear wheels.

Measuring as to ear quality levels as DbA inside measured 92 and outside 102 DbA.
We want final design under 95 DbA and less than 85 DbA inside.

Important to keep in mind is what levels of sound human ears can take

Types of Hearing Loss

There are many different causes of hearing loss. The following are the general categories into which hearing loss falls:

Otosclerosis - is a disease that causes bony growth on the ossicles and causes the stapes to become immobile, thus not allowing sound to be transferred into the cochlea. This is the result of a disease that affects the movement of the stapes, located in the middle ear.

Meniere's disease - is a problem involving fluid pressure within the cochlea. It causes the sufferer to experience intermittent episodes of hearing loss, dizziness, and tinnitus. These episodes can occur anytime and for varying amounts of time.

They are often associated with stress.
Drug induced - some medications can result in damage to the auditory system with prolonged use.
They are called ototoxic. Here are a few drugs that are known to cause hearing loss: aminoglycoside antibiotics (such as streptomycin, neomycin, kanamycin); salicylates in large quantities (aspirin), loop diuretics (lasix, ethacrynic acid); and drugs used in chemotherapy regimens (cisplatin, carboplatin, nitrogen mustard).

Tumors - one of the common tumors in the ear is called a vestibular schwannoma. These tumors develop around the 8th cranial nerve, which is also known as the auditory nerve.
Trauma - trauma to the ear can include fractures of the temporal bone, puncture of the eardrum by foreign objects, sudden changes in air pressure, and very loud noises.

Presbycusis - this hearing loss is caused by natural aging of the human body and begins after age 20, but often it is not noticed until the ages of 55 to 65. Presbycusis affects the high frequencies in the speech range, making understanding and hearing speech difficult.

Noise-induced hearing loss (NIHL) - this is hearing loss due to exposure to either a sudden, loud noise or exposure to loud noises for a period of time. A dangerous sound is anything that is 85 dB (sound pressure level - SPL) or higher.
Dangerous Decibels focuses on noise-induced hearing loss.

Noise-Induced Hearing Loss (NIHL)

Of the roughly 40 million Americans suffering from hearing loss, 10 million can be attributed to noise-induced hearing loss (NIHL). NIHL can be caused by a one-time exposure to loud sound, as well as by repeated exposure to sounds at various loudness levels over an extended period of time.

Damage happens to the microscopic hair cells found inside the cochlea. These cells respond to mechanical sound vibrations by sending an electrical signal to the auditory nerve.
Different groups of hair cells are responsible for different frequencies (rate of vibrations). The healthy human ear can hear frequencies ranging from 20Hz to 20,000 Hz. Over time, the hair cell's hair-like stereocilia may get damaged or broken. If enough of them are damaged, hearing loss results. The high frequency area of the cochlea is often damaged by loud sound.

Sound pressure is measured in decibels (dB). Like a temperature scale, the decibel scale goes below zero. The average person can hear sounds down to about 0 dB, the level of rustling leaves. Some people with very good hearing can hear sounds down to -15 dB.
If a sound reaches 85 dB or stronger, it can cause permanent damage to your hearing. The amount of time you listen to a sound affects how much damage it will cause. The quieter the sound, the longer you can listen to it safely.
If the sound is very quiet, it will not cause damage even if you listen to it for a very long time; however, exposure to some common sounds can cause permanent damage.
With extended exposure, noises that reach a decibel level of 85 can cause permanent damage to the hair cells in the inner ear, leading to hearing loss. Many common sounds may be louder than you think…

A typical conversation occurs at 60 dB - not loud enough to cause damage.
A bulldozer that is idling (note that this is idling, not actively bulldozing) is loud enough at 85 dB that it can cause permanent damage after only 1 work day (8 hours).

When listening to music on earphones at a standard volume level 5, the sound generated reaches a level of 100 dB, loud enough to cause permanent damage after just 15 minutes per day!
A clap of thunder from a nearby storm (120 dB) or a gunshot (140-190 dB, depending on weapon), can both cause immediate damage.

In fact, noise is probably the most common occupational hazard facing people today. It is estimated that as many as 30 million Americans are exposed to potentially harmful sounds at work.

Even outside of work, many people participate in recreational activities that can produce harmful noise (musical concerts, use of power tools, etc.). Sixty million Americans own firearms, and many people do not use appropriate hearing protection devices.


Decibel Exposure Time Guidelines

Accepted standards for recommended permissible exposure time for continuous time weighted average noise, according to NIOSH and CDC, 2002. For every 3 dBs over 85dB, the permissible exposure time before possible damage can occur is cut in half.

Continuous dB Permissible Exposure Time

85 db 8 hours
88 dB 4 hours
91 db 2 hours
94 db 1 hour
97 db 30 minutes
100 db 15 minutes
103 db 7.5 minutes
106 dB 3.75 min (< 4min)
109 dB 1.875 min (< 2min)
112 dB .9375 min (~1 min)
115 dB .46875 min (~30 sec)

11/19/22 06:28 PM Deleting F45 Shocks & not tripping DTCs by teamzr1
If needed to replace to normal shocks, a couple of options to prevent DTCs tripping and controller limiting maximum speed to 80 MPH

Install 10W 10 Ohm wire wound resistors into the shock sensor wire connectors.
Some vendors sell a connector that has the resistor wired in and fool the controller into thinking shocks are present and not tripping the DTCs for them

Or best is going to someone who has a GM Tech-II and program it out with and disconnect the ride control module option

1. Hook a Tech 2 (Driver's footwell), turn the car ON, make sure the module in the left rear storage compartment
(pull back the Velcro lining on the front of the compartment) is plugged in. DO NOT UNPLUG THIS MODULE

2. Now use the Tech 2 to delete the F45 option ( F55 option does not appear on the Tech 2 menu screen -
SO - DELETE THE F45 OPTION

3. Save the new configuration

4. DO NOT TURN THE CAR OFF DO NOT REMOVE THE TECH 2 Go to the module in the rear of the car, unplug the GRAY connector
IT IS THE WIDEST ONE - leave the other 1 (F/45) or 2 (F/55) plugged in.

5. Turn off the car but LEAVE THE TECH 2 PLUGGED IN

6. Remove remaining plugs from the module in the rear of the car - Never plug them back in again, if you do the F/45 turns on automatically.

7. Now the moment of TRUTH - Turn the car on and verify that the dreaded - MAX SPEED 80 MPH - is gone.
This message was only present if you had already disconnected the shock sensors. Some people have had to disconnect their battery to allow the computer to reset to remove this message, but I would confirm with the Tech II that the F/45 was actually deleted first and if not reconnect everything and start again with step 1.

8. Unplug the Tech 2 - Get in the car and take it for a ride. Smile as you pass the DREADED 80 MPH.

11/19/22 05:19 PM GM oil life monitor operation by teamzr1
The GM oil life monitor operation and my statement that ZDP (or ZDDP as you tend to call it here...most of the API literature just sticks to ZDP so I tend to use that) depletion is the basis for oil deterioration.
My spelling is poor but ZDP stands for zinc dialkyldithiophosphate which , as it sounds, is an anti-wear compound comprised of zinc and phosphorus.

ZDP is dispersed in the oil to be at a potential wear site if a surface asperity happens to break through the oil film thickness, causing the dreaded metal-to-metal contact. A molecule of ZDP must be present at that moment to prevent micro welding at the contact site which will cause material transfer, scuffing, scoring, and wear and catastrophic failure.
The concentration of ZDP in the oil will determine if there is ZDP present to work it's magic. The greater the concentration...the more likely a molecule of ZDP will be there...and vice versa.

By nature, ZDP is sacrificial. As ZDP is "used up" at a wear site to prevent micor welding the concentration of ZDP decreases, So if you measure the ZDP concentration in engine oil in a running engine it will decrease at a linear rate based on engine revolutions. Any given engine has a certain number of high potential wear areas where metal-to-metal contact could occur due to reduced film thickness and/or surface asperities....areas such as rubbing element cam followers, distributor gears, rocker arm pivots, push rod tips, etc

The more of these areas, the more ZDP depletion. The more often these features come in contact, the greater the ZDP depletion. That is why, generally speaking, ZDP concentration in the oil, for any given engine, will decrease at a fairly linear rate when plotted versus cumulative engine revolutions. The more times it turns, the more contact the more chance for wear, the greater the depletion.

This is as much of a fact as I could quote ever and is really not speculation or anything. It is proven beyond a shadow of a doubt in many studies. That is why it is ONE of the basis for determining oil life remaining and why it is THE basic premise of the GM oil life algorithm. It is only ONE of the things that determines oil life...but it is the one thing that can be tied to engine operation in a linear fashion and estimated very accurately by accumulating engine revolutions via a counter.

The GM engine oil life monitor counts engine revolutions and accumulates the number for the basis of the oil life calculation. It then adds deterioration factors for operating temperature, start up temperature, soak times, ambient, coolant temperature, etc.

There are a LOT of factors that "adjust" or affect the slope of the deterioration, but the fundamental deterioration is traced back to the ZDP depletion that is inescapable with engine revolutions. The specific rate of ZDP depletion is readily measurable for any given engine, so that is the fundamental item that is first calibrated for the oil life algorithm to tailor it specifically to that engine.

You would obviously like to get the oil out of the engine before the ZDP concentration gets so low that it is ineffective at being at the right place at the right time and preventing engine wear, so that becomes the long term limit on oil life for that application.

The other things that determine oil life such an acid build up, oxidation, petane insoluble’s such as silicon from dust/dirt, carbon or soot build up from the EGR in blow by, water contamination, fuel contamination, etc. are all modeled by the multipliers or deterioration factors that "adjust" the immediate slope of the line defined by the engine revolution counter as those items can be modeled in other ways and accounted for in the immediate slope of the ZDP depletion line.

The algorithm was developed over the course of many years by several lubrication experts at GM Fuels and Lubes, spearheaded by Doctor Shirley Schwartz who holds the patents (with GM) for the algorithm and the oil life monitor. I had the luck of working directly with Dr. Schwartz when the idea of the oil life monitor first progressed from the theoretical/lab stage to real world testing/development/validation.

There were fleets of cars operated under all conditions that deteriorate the oil life for any and every reason and, through oil sampling and detailed analysis of the oil condition, the algorithm was developed, fine-tuned and validated to be the most accurate way invented yet to recommend an oil change interval by.

As just one example, I have seen cars driven side-by-side on trips, one towing a trailer and one not, for instance, to prove the effectiveness of the oil life monitor in deteriorating the oil at a faster rate just because of the higher load, higher average RPM, higher temps, etc and it works flawlessly.

The oil life monitor is so effective because: it is customized for that specific vehicle/engine, it takes everything into account that deteriorates the oil, it is ALWAYS working so as to take into account THAT INDIVIDUALS driving schedule, and it tailors the oil change to that schedule and predicts, on an ongoing basis, the oil life remaining so that that specific individual can plan an oil change accordingly. No other system can do this that effectively.

One thing is that I know personally from years of testing and thousands of oil analysis that the oil life algorithm works. There is simply no argument to the contrary. If you don't believe me, fine, but, trust me, it works. It is accurate because it has been calibrated for each specific engine it is installed on, and there is considerable testing and validation of the oil life monitor on that specific application. Not something that oil companies or Amsoil do.

They generalize the oil life monitor is very specific for that application. Oil condition sensors in some BMW and Mercedes products are useful, also. They have their limitations, though, as they can be blind to some contaminates and can, themselves, be contaminated by certain markers or constituents of certain engine oils. Oil condition sensors can only react to the specific oil at that moment, and they add complexity, cost and another potential item to fail. One other beauty of the GM oil life monitor is that it is all software and does not add any mechanical complexity, mass, wiring or potential failure mechanism.

There is considerable safety factor in the GM oil life monitor. Typically, I would say, there is a 2:1 safety factor in the slope of the ZDP depletion curve....in other words, zero percent oil life per the ZDP depletion is not zero ZDP but twice the concentration of ZDP considered critical for THAT engine to operate under all conditions reliably with no wear.
This is always a subject of discussion as to just how low do you want the ZDP to get before the oil is "worn out" if this is the deciding factor for oil life. We would tend to be on the conservative side. If the oil life is counting down on a slope that would recommend a 10K change interval then there is probably 20K oil life before the ZDP is catastrophically depleted, not that you would want to go there but the reason why many people are successful in running those change intervals.

There are entire SAE papers written on the GM oil life monitor and one could write a book on it, so it is hard to touch on all aspects of it in a single post. Hopefully we hit the high spots. Realize that a GREAT deal of time, work and energy went into developing the oil life monitor, and it has received acclaim from engineering organizations, petroleum organizations, and environmental groups all across the board. It is not some widget invented in a week.

11/17/22 04:54 PM Nick Tandy No Longer Driver for Corvette by teamzr1
Nick Tandy said the FIA World Endurance Championship season finale at Bahrain was an “emotional” experience, knowing that it was his last time working with Corvette Racing for the time being.

The Englishman will depart the Pratt Miller-run factory team for a new opportunity beginning next year, following a successful two year-stint.
Tandy and co-driver Tommy Milner took part in a full-season campaign in the WEC this year, highlighted by GTE-Pro class victory in the 6 Hours of Monza, and previously was part of the team’s IMSA WeatherTech SportsCar Championship campaign, also with the Chevrolet Corvette C8.R.

“Honestly, it’s sad to talk about summing up the end of what’s happened the last two years,” said Tandy.
“I’ve been lucky enough to be part of this team, which is something not a lot of drivers can say.
“I’ve been lucky to race this awesome race car in the two best sports car championships in the world.
Not many people get to be in my position, so I feel very fortunate for that.

“Along the way, I’ve made lifelong friends within the team. I’ve met so many enthusiastic and committed Corvette owners and fans who three years ago wouldn’t have talked to me, but now they’ve taken me on and treated me like one of their own.”

Tandy, who has been linked to a return to Porsche for its factory LMDh program, hasn’t ruled out one day returning to the GM fold.
It’s farewell, but maybe not goodbye,” he said. “We never know what the future holds.

When I first joined the team, my plan wasn’t to finish in two years. Things within the sport changed and plans within the team had to change.
Luckily, I have somewhere else to go where I will still see all my friends in this team across the paddocks.

“It’s been an awesome two years. I’ve thoroughly enjoyed every day of work, which you can’t often say.
There are good days and there are very long days, but even the long days with Corvette Racing are still filled with fun and excitement.
Those race days and especially the days when we won are days I will hold forever.
Thank you to Corvette Racing, Chevrolet, General Motors and especially each and every member of this team who has taken me in as one of their own.

“We’ve spent the last two years having a great time in professional sport together.”
He turned his final laps in the GTE-spec Corvette C8.R during Sunday’s WEC rookie test, to help dial in the car for Corvette newcomer Ben Keating and several Silver-rated drivers that are under evaluation for the team’s move to GTE-Am next year.
It quickly turned into an emotional experience for the 38-year-old.

I left the pit lane for my last run in the test and Tyler [Neff, race engineer] and Tim [Kavanagh, car chief] came on the radio and said ‘Right, these will be your last few laps, said Tandy.

It hadn’t dawned on me that it would be the last time I’d drive the C8.R and in the GTE configuration.
I left the pit lane and this struck me.
At the end of the run, it was completely unexpected to see the whole team out in the pit lane with a great big signboard with a specially written slogan for me, which is quite funny!

To see them waving all the flags just for me… it was pretty emotional.
And we got red flagged for the enthusiasm of the team, which I didn’t know at the time!

“It’s an overwhelming and emotional thing. I’m just one member of a great big group of people who go racing together.
It’s nice to see that people have appreciated my time here, and it’s sad we won’t be doing it again in January.”

11/17/22 12:46 AM Corvette Straight Into 2023 Prep FIA WEC by teamzr1
CORVETTE RACING AT BAHRAIN: Straight Into 2023 Prep FIA WEC test in Bahrain sees Keating, prospective drivers behind the wheel of C8.R

SAKHIR, Bahrain (Nov. 16, 2022) – Shortly after closing its season with a heroic runner-up class finish in the Eight Hours of Bahrain for the FIA World Endurance Championship, Corvette Racing was back on-track for a one-day test ahead of the team’s 2023 campaign.


Ben Keating, already confirmed to drive the Mobil 1/SiriusXM Chevrolet Corvette C8.R next year in the WEC, got his first laps in the mid-engine racer Sunday along with two prospective teammates: Axcil Jefferies and Nicolas Varrone. Once a final decision comes, the three will focus on winning races and a championship in the GTE Am category, the first season for Corvette Racing in the class after a decade-plus as part of GTE Pro.

The sporting rules of the GTE Am category require at least one Bronze-level driver Keating in this case as rated by the FIA. One professional-level driver Catsburg is allowed along with a second Bronze or Silver-rated driver. That trio will contest the full seven-race WEC calendar, including the 24 Hours of Le Mans in June.

Corvette Racing ended its first full FIA WEC season with a runner-up finish by Tommy Milner and Nick Tandy in the No. 64 Corvette.
The team will open the 2023 season with the 1,000 Miles of Sebring on March 17.

GM SPORTS CAR RACING PROGRAM MANAGER:

"First off, thanks to Nick Tandy for the two years he spent with Corvette Racing and what he did to elevate the team and our program in both IMSA and the WEC.
Having he and Tommy Milner as part of our lineup for our first season in WEC was a great experience with some fantastic results."

(On 2023): "We're really excited based on the results of our preliminary testing for 2023. Ben got in the car and was strong right off the bat, which is exactly what we expected. We know Nicky (Catsburg) does well based on his history with us.
The pace of the silver-rated drivers we tested was good. We’re eager to decide on the right fit to complete our lineup.
There is a lot to look forward to in our return to the WEC next year with a competitive team and car in a new class. I feel like we are off to a good start."

BEN KEATING:

Those first laps were excellent. The feel of this car is significantly different from the Aston Martin that I've been driving the last two years and the last three days. I don't know how many laps I did, maybe 10 laps this morning, and I'm still learning a lot about the car. It's very impressive.

It's fun for me as a driver. I think I've driven almost every single GTE car now, and they're all a little bit different in the way you find speed.
Obviously the Corvette is no different. You have to learn where to find the speed and how to work the car. It's been fascinating.
In looking at the data, and as an example, I was one gear too low in every single corner; I was over-slowing the car in every single corner than what I needed to because my brain isn't calibrated to how quickly the Corvette can go through a corner. That's just an example of the things I need to learn, and I'm excited to do that.”

(Outlook for 2023): "I'm really looking forward to running in the Corvette.

I pay for all of this racing by selling cars, and I'm super excited to get back into racing a car that I sell back in Texas at my Chevrolet dealerships. I'm super excited to race for an American manufacturer with an American team. Almost everyone in the garage sounds like I do!
When we win a race next year, we'll get to hear the American national anthem.
That'll be special. I'm very excited about what next year holds for us as we learn to gel and as Corvette Racing learns what it's like to be in GTE Am for the first time."

NICOLAS VARRONE:

"I'm really delighted. Thanks to Ben Keating and Corvette Racing for the opportunity. It's just an amazing car, a pure racecar that I enjoyed driving. It's really fun. The brakes surprised me. The braking efficiency is really amazing. There was a learning experience because I'm used to other cars, but the team helped me a lot during the day to try new things and improve every time I went on track. It was good, and I enjoyed it a lot."

AXCIL JEFFERIES:

"Honestly, the car feels great.
Not only that, but the team is fun to work with. It's a really nice group of guys. It was nice getting up to speed with the car. I expected quite a lot from the car. Obviously

it's a factory program and I expected everything set to the highest level, and it really delivered.
It would be great if this opportunity could happen in WEC. Let's see what how it works. I tried my best, and now the decision will be up to the team and Ben."

11/09/22 03:57 PM CORVETTE RACING AT BAHRAIN - Last Race for 2022 by teamzr1
Final GTE Pro race in WEC sees Milner, Tandy going for second victory of the season

DETROIT (Nov. 8, 2022) – Corvette Racing will put a cap on its first full year in the FIA World Endurance Championship with its initial trip to the
Middle East for the season-ending Eight Hours of Bahrain.

As they have all season, Tommy Milner and Nick Tandy will pilot the No. 64 Mobil 1/SiriusXM Chevrolet Corvette C8.R in Corvette Racing’s first trip to
the Middle East.
A new venue doesn’t intimidate the team, as it has a victory at Monza in its Italian debut. Bahrain will be the 33rd different track for
the Corvette program.

Another victory not only would close out the WEC season in the best way possible, but it also would put Corvette Racing in the history books as the
winner of the final GTE PRO race in the championship.

The category has been part of the WEC since the 2011 season, and the technical regulations matched the GT Le Mans (GTLM) class in the IMSA
WeatherTech SportsCar Championship from 2014-2021.
In the GTE/GTLM era, Corvette Racing has recorded 33 victories across WEC and IMSA competition.

The 3.363-mile, 15-turn Bahrain International Circuit is unique in multiple ways.
It features less than 17 meters of elevation change over the course of a lap, and the entire lap, all but the exit of Turn Four – is run below sea level.

As expected, it’s a very arid circuit, with desert sands and rocks bordering the racing tarmac and runoff areas. In many ways, Bahrain is similar to
WeatherTech Raceway Laguna Seca on the IMSA calendar. There, sand and dust constantly blow across the track surface, which puts a premium on generating
grip and maximizing tire life.

While the track surface at Bahrain is much smoother and less destructive to tires compared to Laguna Seca, the significantly warmer air and track
temperatures at Bahrain compared to the Monterey Peninsula will make it a challenge to prevent sliding of the tires across the track surface.
To that point, tire performance will play a significant role in the outcome of Saturday’s race.

The No. 64 Corvette opened the WEC season with a strong second-place showing at the rain-shortened 1,000 Miles of Sebring. Things were trending in the right
way for the Tandy/Milner pairing at the Six Hours of Spa before a red flag just past the one-hour mark wiped out the team’s first planned pit stop and
effectively put the Corvette a lap down before finishing fourth.

The 24 Hours of Le Mans was a cruel blow with the No. 64 C8.R eliminated while leading just shy of the 18-hour mark. Spirits lifted within the team
following a thrilling class victory at Monza where, the team won a fuel-mileage race for its first WEC win outside of Le Mans. Milner and Tandy
finished fifth on a challenging weekend at Fuji in September.

The Eight Hours of Bahrain for the FIA World Endurance Championship is scheduled for 2 p.m. Arabian Standard Time (AST) / 6 a.m. ET Saturday from
the Bahrain International Circuit. Qualifying is set for 4:50 p.m. AST/8:50 a.m. ET on Friday.
The race will air live on MotorTrend with live-streaming coverage of the race and qualifying on the MotorTrend Plus app.
Radio Le Mans will broadcast qualifying and the race.


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

“The track surface at Bahrain is pretty unique in general. To simplify it, you have big stones and little stones, polished and unpolished. It’s totally different
Then anywhere else we go. From the sim work we’ve done, it feels like there is a lot of grip. From what other drivers and teams have said, it’s a track
that is aggressive on tires.
That correlates pretty well with what we’ve seen in the simulator. I’d imagine the first practice session will be quite difficult as we dust off the track a little bit. It’s a circuit that is a little bit like Fuji with some long-duration corners and medium- and high-speed stuff. There are lessons we took from Japan that can apply here.
The track surface being unique, and its characteristics will play a big role in the strategy for the race.”

“I’ve raced in the Middle East once before at Dubai, so I have a little bit of understanding of the culture. It sounds like Dubai and Bahrain are
similar in some ways. The fans were awesome when I went, and it was a cool place to go see, and I’m sure Bahrain is similar in many ways. I’m excited
to get there.”

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

“I raced at Bahrain for the first time in 2010 and went there twice before in WEC. I’ve never driven a GTE car around there, so this will be fun. The effect of the
sand on the tire and how the tire interacts with the surface how each car reacts to the sand blowing around – and it does quite a lot, can affect
things quite a lot. It’s one of the challenges.
It can be very gusty and windy, and the direction can change. This is another factor with the
high-downforce cars that we have. When it’s windy, it does have an influence on the race, and it can change lap by lap.”

“It’s an interesting circuit and good for racing and good to drive. Bahrain rewards consistency because you see the highest level of tire wear of any
track we go to. You have to have consistent and clean driving, and the track punishes over driving.
This is good because you always want to influence a race as a driver.”

“One of the good things there is that you have linked corners to corners, where what you do in the first corner influences what happens in the next. You
have places like turns One and Two, and then you have the Esses in the middle of the track, and the fastest section is in the middle.

You have to figure out how to best get time out of them, whether you give up time in the first part to improve the second section or second corner. That’s always nice as opposed to have a straight, a hairpin and then another straight.
Those races are kind of car-defined, whereas with these types of corners, you can as a driver effect more of what’s happening and affect the laptime.”

10/27/22 01:19 AM GM Fix 2022 Corvette For Battery State Of Charge Underestimation by teamzr1
GM has started a service update to address a problem with certain 2022 Corvette Stingray units that may cause the vehicle to display a low charge status warning, despite the battery being full.

The problem: affected 2022 Corvette Stingray models have a condition that may cause an underestimation of the 12-volt battery state of charge.

The hazards: If this occurs when the battery is sufficiently charged, the alternator may not enter fuel saving mode, negatively impacting fuel economy.

The fix: an over-the-air update will be pushed to vehicles to remedy this problem.
An over-the-air update is an internet-enabled update that can be sent to vehicles wirelessly without the need to visit a dealership.
Owners who still wish to take their vehicle in for service can also have the body control module (BCM) reprogrammed by a GM technician.
This software update will be performed at no cost to the vehicle owner.

Affected components: body control module (BCM).

Affected vehicles:
• 2022 Corvette Stingray

Number of affected vehicles: it’s unclear how many vehicles will need an OTA update or BCM software update to address this problem.

Owners should: involved vehicles will receive an over-the-air update via the OnStar system.

Contacts:
• GM service update number: N212351870

10/21/22 01:52 AM Onstar means OnSpy by teamzr1
Very few know GM has been sneaking in one function via Onstar called "Smart Driver"
Most owners do not even know this was turned on without their being told so
One C8 owner just finds out after driving his C8 for 2 years that this Onstar function not only spying on your driving habits but also is reporting it to like credit agencies and vehicle insurance

Guy states :

I took delivery at the dealer and activated OnStar 2 years ago.
When I was looking at all the OnStar features, I signed up for "Smart Driver" on my phone.
I looked at the data once or twice since then and now can see
the Hard Brake Events, Acceleration Events, High Speed MPH Events etc. on my drives.

I just sent for my credit report info from LexisNexis and saw that GM had been reporting the same data to them that I was seeing.
Needless to say, I was not thrilled. My insurance company had inquired about that data a couple of times and luckily my rates haven't gone up, YET

I just wanted to let anyone know that has the feature "Smart Driver" on their OnStar account to realize the info can be going to your insurance company via your credit report.
This is all GM vehicles, and recall I reported a few months back starting with 2023 models GM forced a mandatory 3 years of Onstar contract, and they add that cost to your buying price, and you cannot opt out of it.

Those with that GM my car APP on their cellphone better go check and turn OFF "Smart Driver"

I have been ranting for years that Onstar ( out of China) is spying on all of you with Onstar even if you did not buy any GM Onstar services
But do not forget all other nameplates pull the same crap as Ford that has Microsoft and Google installed on those vehicles and also spying big time



Now that people are getting learned about Smart Driver

This C8 owner checked his and is crying as to his own C8 is snitching on him smile
Of course a 100 is an A+, you're a pansy ass that never hard launches or speeds

This guy getting only a grade of 50, and he only checked for the last week

For 7 days, the spies know he drove the C8 12 times

Hard braking - 18 times, etc
Hard launches - 65 times !
Almost 20% of time drove over 80 MPH :-(

Wonder what he and spies see for over 1 months time
People are finding they turn smart driver off, and later they find it is back on again

He's screwed smile

10/18/22 02:29 PM C8.R Z06 Racing for 2023 by teamzr1
In its 25th season of top-level endurance racing, Corvette C8.R Racing will continue its long-running commitment to the IMSA WeatherTech SportsCar Championship in 2023 as part of the GT Daytona (GTD) PRO class while taking on a new challenge by transitioning into GTE Am competition in the FIA World Endurance Championship.

For the second year in a row, Corvette Racing will enter one car in each of sports car racing’s most prestigious championships.
The premier races in the world will be part of the schedule for the Mobil 1/SiriusXM Chevrolet Corvette C8.R including the Rolex 24 At Daytona, 24 Hours of Le Mans and the Mobil 1 Twelve Hours of Sebring, among others.

“We learned a great deal this year about running dual programs in both IMSA and the FIA WEC all of which will benefit the Corvette brand going forward,” said GM Sports Car Racing Program Manager.
“In IMSA, we will return to GTD PRO against a very competitive group of manufacturers while laying the groundwork for the Corvette Z06 GT3.R. Similarly, Corvette Racing’s FIA WEC program allows us the opportunity to continue growing the global presence of Corvette in a world championship.”

Corvette C8.R will again join the grid in the World Endurance Championship as a full-time entry, this time in GTE Am. The C8.R will be driven by Nicky Catsburg, who moves to full-time duty in a Corvette for the first time, and highly successful Bronze driver Ben Keating widely considered one of the world’s best privateer drivers.

The sporting rules of the GTE Am category require at least one Bronze-level driver, as rated by the FIA.
One professional-level driver is allowed along with a second Bronze or Silver-rated driver. Corvette Racing will confirm the final member of the WEC lineup at a later date.
The trio will contest the full seven-race WEC calendar including the 24 Hours of Le Mans in June.

Keating is a past winner at Le Mans, Daytona, Sebring and many of the other premier races in WEC, IMSA and Intercontinental GT Challenge. The personable Texan began racing in 2006 and quickly established a reputation as one of sports car’s fastest and most reliable amateur drivers in both prototype and GT categories. He races with the support of Four Horsemen Racing and Wynns.

While Keating will race a Corvette for the first time, Catsburg has established himself as a fixture with the marque. Since joining the program in 2020, Catsburg recorded a victory at Daytona in 2021 and Sebring this year alongside Antonio Garcia and Jordan Taylor.
The 2023 campaign will be Catsburg’s first in the World Endurance Championship since 2019. He also has wins in long-distance races at the Nürburgring, Spa and Indianapolis Motor Speedway, among other venues.

Garcia, Taylor back in IMSA GTD PRO full-time

With two championships in three years together, the aforementioned Garcia and Taylor will reunite for another run at the GTD PRO title in 2023.
Like this year’s effort, the familiar yellow Corvette will run in a modified state to fit the C8.R in the performance window of GT3 cars that make up both the GTD PRO and regular GTD entries in the WeatherTech Championship.
The 2022 season was a learning experience for both Corvette Racing and IMSA as the two groups work together on balancing the C8.R and the rest of the GTD category from technical and competitive standpoints.

The victory at Sebring for Garcia, Taylor and Catsburg was the highlight of the 2022 season, which also included runner-up finishes at Canadian Tire Motorsport Park and VIR.
Garcia is a five-time IMSA champion dating back to 2013. He has made 136 starts with the program since joining as a long-distance driver in 2009. Among his career highlights include two Rolex 24 wins, two Le Mans wins and five victories at Sebring.

Taylor is a four-time IMSA champion with two coming in the GT Le Mans (GTLM) ranks with Garcia in 2020 and 2021. He joined Corvette Racing in 2012 as a long-distance third driver and won the 24 Hours of Le Mans in 2015. He moved to a full-time role in 2020 the same season the C8.R made its competition debut.

Milner back to IMSA, focusing on GT3 development

Tommy Milner, currently contesting the full WEC for Corvette Racing, will take over the endurance driver role in the WeatherTech Championship for 2023. He will drive with Garcia and Taylor at Daytona, Sebring and the 1,000-mile Petit Le Mans.
Milner also will serve a key role as the primary testing and development driver for the Corvette Z06 GT3.R, which will be available to customer racing teams starting in 2024.

Milner made his 130th start with Corvette Racing at the most recent WEC round at Fuji and has been part of the program as a full-time driver since 2011.
He is a two-time IMSA champion, claimed a pair of victoriesChevrolet is in the midst of an extensive development program for the Z06 GT3.R using both on-track testing and the manufacturer’s Driver-in-the-Loop simulator.
The latter has been the focus for more than a year as Corvette Racing continues to refine items such as chassis platform, traction control, ABS and other tools that are features of GT3 racing.

The Corvette Z06 GT3.R will leverage the strong foundation provided by the mid-engine Corvette Z06 supercar.
The Z06 GT3.R will share the same aluminum chassis, a production engine modified for use in the racecar, and similar aerodynamic features.
At the heart of the Z06 GT3.R is a 5.5-liter, DOHC LT6 V8 engine with the same flat-plane crankshaft architecture that powers the Corvette C8.R and the production Corvette Z06.

Corvette Racing’s 2023 IMSA campaign kicks off with the Rolex 24 At Daytona on January 28-30, while the FIA WEC season begins with the 1,000 Miles of Sebring on March 17.

NICKY CATSBURG, CORVETTE C8.R FOR FIA WEC IN 2023:

“It’s been my goal from the get-go when I joined the team to be a full-time Corvette Racing driver. It’s super-cool to do races like Daytona, Sebring, Le Mans and Petit Le Mans. But I knew that I always wanted to do something full-time with the team.
I’m super happy and proud that it’s happening and that I can call myself a full-time Corvette driver. It’s super-nice. It’s a dream come true and I can’t wait to get this going.”

“WEC is a cool program. You get to travel around the world and race at some of these great tracks. Ben is the best Bronze driver out there right now and consistently performs very well. I will miss GTE Pro because it was great fun being part of factory racing at Le Mans. But I’m excited to start working with Ben. I’ve been seeing him around for a number of years and he always does a fantastic job. I’m looking forward to this. This is a place that any driver wants to be.”

BEN KEATING, CORVETTE C8.R FOR FIA WEC IN 2023:

“I really love the format of the World Endurance Championship and GTE Am. I’ve really wanted to race a Corvette for a long time and have been chipping away at this to make this happen because I want to race what I sell. I’m in the unique position of enjoying cars as a vocation and a recreation. This is something I’ve been dreaming of for a long time. I’m incredibly excited for this opportunity.

“I know that Corvette Racing is really excited about the program and I am too. There’s just something special about the 100th anniversary of Le Mans, the last year of GTE-spec cars and something special with an American driver racing for an American team. I’m excited that when not if! we win a race that we will hear the U.S. National Anthem.
I haven’t had that because I’ve driven for British and German teams. So this will be awesome. The Corvette fans are crazy and fanatical! Getting to represent a brand that I sell and be part of that community is something that’s important to me and I’m excited about it all the way through.

“My number one thing about teammates is that I’m doing this for recreation and for fun, so I really want to enjoy who I’m racing with. Having been teammates with Jeroen Bleekemolen for a number of years and both of them being Dutch, Nicky was kind of always around! So I’ve always felt a good connection with Nicky. Even though we’ve never been teammates, I’ve paid attention very closely to him.

I remember him testing a Corvette for the first time at Le Mans, and I wasn’t surprised when he went out and set the fastest GT lap of anyone in the field on the Test Day! So he is fun to watch. He’s extremely quick and is someone who knows all the tracks in the WEC and is someone I get along with extremely well. I’m super excited to be teamed with him.”

ANTONIO GARCIA, CORVETTE C8.R FOR IMSA IN 2023:

“America has become a second home for me since I started with Corvette Racing in 2009. I enjoy the people, I enjoy the racing and I enjoy this Corvette. IMSA has a lot of great events and tracks all of which I’m very familiar with now!

“I have to say that this season was very difficult and challenging, maybe more than previous years. Still I think we learned a lot as drivers and as a team about a new category that we can use to make us better in 2023. Hopefully Jordan and I can get back to winning races and being in the championship fight. It also will be an important year as we get closer to finishing testing and development of the Corvette Z06 GT3.R, which will be a big deal.

I’m happy that Tommy will be part of that and with us for the big races in America. We were teammates in his first year at Corvette and we’ve raced against each other in previous versions of the Corvette since then. I’m glad to be able to race with him again.”

JORDAN TAYLOR, CORVETTE C8.R FOR IMSA IN 2023:

“It’s great to be back with Corvette Racing for its 25th year. I remember as a kid watching my dad race, and Corvette already had a strong reputation for being competitive and winning big races. So it means a lot to be able to continue on with Antonio, Tommy and the rest of the team in 2023.

“We definitely want to be back stronger at Daytona than how we left Petit Le Mans. We had some decent races winning Sebring in a Corvette was unreal but I think we all were frustrated with how things went as a whole. We have an opportunity to improve on some things that we can control, which is what this team is so good at doing.
By the time we get back to Daytona in January for the Roar, I’m confident we’ll be in a position to succeed to a greater level than a year ago.”

TOMMY MILNER, CORVETTE C8.R FOR IMSA AND Z06 GT3.R DEVELOPMENT DRIVER IN 2023:

“I’ve not driven a lot in my career with Jordan or Antonio. But when I have, we’ve had success. I’m always excited to drive with those two guys. They’re obviously great drivers and great teammates, and they have been for a long time.
I’ve raced against them quite a bit in my time so it’ll be fun to be teammates with them for a change.

“The process of developing the Corvette Z06 GT3.R will be an interesting one. I did quite a bit of this with the C7.R and C8.R. It’s different from racing of course, but it can be a rewarding process in its own right.
This year was fun because it was something totally different. Next year will be something different again, and that’s a good thing to do different things every now and then. It’s an honor to be a part of this racing team and program.

Having been part of testing many of the previous Corvettes, we’ve seen how fast and competitive those cars are.
I’m excited and looking forward to keeping that lineage going.” at Le Mans and scored his first WEC race victory outside of Le Mans in July at the Six Hours of Monza.

10/18/22 12:55 AM C8 Z51 Not a Racer ? by teamzr1
Owner of a 2022 C8 Z51 just did the Big Bend Open Road Race this month of Oct where weather was around 90 degrees

He states :

During a long road race last weekend, my un-modded 2022 Z51 put itself in a reduced power mode that ruined the race for me.

I was only to 32 of 60 miles for the first leg into the race,
averaging about 155 mph with a top speed of 168 mph when an orange DIC message popped up with a message about a transmission temperature problem.

Press check to dismiss it said. I pushed check and the message went away. But the car speed started to drop.
Foot to the floor accelerator and the max speed was 155, then 150, then 140.
For a while, it would not go faster than 126 MPH.

I could not get it into anything above 6th gear.

When I looked at it later, I found that 50 percent of each of the two front grills ( with those crap 3rd party screens on) were covered with a thick layer of flying bugs similar to a small butterfly.
They were stuck firmly to my grill guards.

Later, using a data dump from the PDR using PI Toolbox, I found that the coolant, oil and transmission oil temperatures were all running 20 degrees hotter than I have recorded in previous races but nowhere near max temps.
I am assuming that the bug layer blocked the air flow and caused these temperature rises.

Did the elevated fluid temperatures cause the car to reduce power and not run above 140?

If I take it to my dealer and tell him that the car doesn’t run well at 160 mph, I can guess what the response will be.

What fluids do the two front grills provide air for cooling?

So finally some C8 owner reports racing a C8 Z51, and it becomes a dog within 32 miles :-)
DCT temps recorded as shown below is nowhere near a condition to limited to only 126 MPH

Thus, another C8 design and the DCT flaw shows up 4 years into the C8 production and would have shown up much sooner
if the C8 owners were not wazers and never racing America's Sports Car mad

10/14/22 02:59 AM Will Factory Corvette Racing exist after 2023 ? by teamzr1

Chevy will initially focus on U.S. customers for its Corvette Z06 GT3.R when it debuts in the 2024 Rolex 24 at Daytona, with a full rollout to Europe to come either at the end of 2024 or early 2025 according to GM sports car racing program manager.

The all-new Pratt & Miller-built GT3 car, which recently completed its first track-based test at Mid-Ohio, is set to have an initial presence in the IMSA WeatherTech SportsCar Championship and Fanatec GT World Challenge America powered by AWS, with additional regions and series to follow.

Klauser, however, hasn’t ruled out having a “couple” of Corvettes in Europe for the “right” series, likely referring to the FIA World Endurance Championship for the launch season of its new GT3-based Pro-Am class.

“We intend to have customers,” Klauser told reporters during an IMSA-hosted Zoom session on Wednesday.
We are going to start slow in 2024 just because we can only build them so fast.

Then we’ll grow from there. We’ll make sure anyone who takes delivery of a car and is racing has our complete support behind them from Corvette Racing.
“We want to make sure they do well because they show well for us, and we want people to know that we’re serious about this car.”

When asked on the specific market plan, Klauser said:
Our first focus will be the United States; that’s our home market, that’s where the majority of our production car sales are.

It’s home, so it’s a lot easier to figure out support where it’s all in the same country.
But we’re not turning a blind eye to anything else.
We know the big volume for GT3 is in Europe and the Asia market is growing as well.

While you might see us primarily in the U.S. to start, there is a growth plan to get to Europe and eventually Asia as well.
We’ll place a couple in Europe if we have a good fit, and it’s the right series.

“In terms of the bulk of the volume to start, it will be in the U.S., with Europe quickly coming in behind, either at the end of ’24 or beginning of ’25.”
GM has yet to define the number of cars it will make available in the first year of the customer program, although Klauser said it will likely be in the range of 10-12.
“That part we’re still working through,” she said. The [FIA] regulation is that you have to build 20 in the first two years.

It’s an easy one to say that [we’ll do] ten a year, but realistically we’re going to for sure meet the requirement but placing cars with the right teams in the right places.
We’ll see how much that shakes out.“It’s not going to be off-the-bat having 30 cars racing all over the world in 2024.

“It will probably be a little bit of a slower walk than that, maybe 10-12 in total, and they won’t [all] be starting the season. We’ll get there when we get there.”
She indicated that it’s Corvette’s goal to have all of its selected customers that’s committed to the 2024 WeatherTech Championship season to be on the grid for the Rolex 24.

Corvette Racing’s Future as Team Yet to Be Announced

Whether Corvette Racing will have factory entries in the GTD Pro class of the WeatherTech Championship in 2024 remains yet-to-be-announced, according to Klauser.

Understood the team will return for a full WeatherTech Championship and likely parallel FIA World Endurance Championship program next year, in GTD Pro and GTE-Am, respectively, although details on that have yet to be formally announced as well.

“As we work through this plan, it’s about what makes sense for the car, for the brand and working through all of that. So that will come later once we’re ready to make that announcement,” Klauser added.

10/12/22 08:34 PM C8 Headlights on during the day TSB by teamzr1
The headlamps may be turning on automatically during daylight conditions instead of the Daytime Running Lamps (DRL) on some 2022-2023 Corvette models. DTC B108E (Ambient Light Sensor Signal) also may be set.

The ambient light sensor is used to monitor outside lighting conditions. The Body Control Module (BCM) monitors the ambient light sensor signal circuit to determine if outside lighting conditions are correct for either Daytime Running Lamps or automatic lamp control when the headlamp switch is in the AUTO position

If the headlamps and DRL concern is present, do not replace the ambient light sensor or any other parts.
Updated software is available to reprogram the BCM for 2022 model year vehicles to address the lighting operation.

The updated software also may be available as part of an Over-the-Air (OTA) programming event. Customers should be advised to watch for any updates on the infotainment system.

For 2023 model year Corvettes with the headlamp operation condition, updated software may not be available yet.
For these vehicles, it is recommended to check the headlamp switch setting and for an illuminated Lights On Reminder symbol on the instrument cluster to ensure the headlamps are on when driving in low lighting conditions. (Fig. 7)
