After installing the HPT pcm, I noticed my Idle Air Control Valve was responding strange. When in P or N, the IAC value is fine (around 50). As soon as the car is put in gear, the IAC counts immediately go to 255 and stay there.
Anybody else noticed this? Are there any existing tables that could have an effect on this?
I currently have the LS1 MAF tables installed and have bumped the idle 200 in P,N and 300 in gear.
