Stock engine at idle around sealevel is around 30-35 KPA Map. Compare 10-30 KPA when fuel learn is ON and you also see less then 30 KPA, torque less then 30 lbs to negative where 30 plus KPA engine is pulling more engine load and timing to maintain idle
We are at about 500 m here (1640 ft), at hot idle I see about 30 kPa.
With AutoTap I can't see if the fuel learn is on, or at least I don't know how (do you know if Autotap can do that?)
Your values almost look like your scanner is backwards and not KPA but in inhg
I adjusted the values to fit the LS1Edit IFR table. It's easier to compare / change the values. According to the scanner the pressure is in kPa (??) and not in inHg
