Thanks in advance for the help... I have a 2010 Tahoe 5.3L that I recently transplanted a 6.2L out of a 2007 Escalade EXT. It was a complete engine with the following components
09359409 Map sensor
12580681 Injector
15900023 MAF
The engine has VVT now, and didn't before, however it has flex fuel and DOD before and now doesn't.
Couple issues I am having is this. I compared a 2007 6.2L file from the HP tuners data base, and I first tried to just change all maps hoping it would be as easy as that. (never is right...) The truck didn't even want to run at all, and was extremely lean. Data log was showing short terms and long terms adding a bunch of fuel. It also throws a map sensor performance high code, which is very odd because at zero vacuum, the car is showing about 120KPA on the log.
I got the car running to move around now by adjusting the MAF table but the car goes into limp mode constantly and has the map sensor performance high code constantly.
What would cause the map sensor to read so high? Offset and linear is set to stock settings. All the searching I have done tells me this is a 1 bar map sensor.
If anyone can help that would be great. Thanks again for the help.
