Car is a 2003 Corvette
has a fast 102 with an LS2 TB (ETC with No IAC motor)
original TB is ETC with IAC motor
this harness is supposed to eliminate the IAC...
the problem we are having is that the car will not idle...
once it starts commanding IAC it just goes nuts..
commands differnt values for IAC desired, but doesnt see anything back(just reads that it stays pegged at 310)
should I be seeing it return info other than 310 IAC position
or did I miss something in the tune that I need to change for it
I have changed the ETC scalar to reflect the new TB size
I have brought the Idle air up to a point where it hold the idle at roughly 100ropm above desired idle until it comes to a complete stop and tries to enter into adaptive idle.
any help is greatly appreciated..
