Couple of questions about tunes and ecm - 2010 GT500
I have the classic issue of three monitors not completing...Oxygen sensor heater, oxygen sensor monitor and catalyst sensor. All other tests completed and no error codes and no check engine light after driving 1000+ miles since Gen2R budget kit (2.5" pulley) installation with BAP. I asked VMP to check their original tune send to me since it is now on the car. Completely stock exhaust still. Scanner shows 23 engine starts and 1700km since last DTCs cleared.
Question: Can any parts of the original stock tune cause this issue even after the VMP tune is loaded onto the ECM in the car? Both tunes load and will start the car with no errors...but I ask this because when I save my stock tune to my PCs it saves but gives me a message - saved but with errors - check the error log -- wherever the hell that is??
Next Question: With one of my scanners I can see the voltage readings changing from the O2 sensors while running and I can see the cat temp (490C ??). So I know the connections to them are all hooked up. Would I still be able to see them even if the tuner somehow disabled these functions in the supplied tune?
Thanks
