Howdy,
Well I got the L67 ECM LC2 engine combo running and driving! After messing around a lot to get most of the sensors logging I started experimenting with trying to get the car to respond to changes. The first thing I tried to do is get it to idle down but it's not doing it. I've left the idle tables stock for a GTP but can't remember if I connected the P/N trigger wire (think I did though).
I can't get it to idle below 1000rpm or even really do anything to the idle through the tune. Using the scanner I can take manual control over the IAC and force it to idle down by changing the counts but no effect when I release it back to the computer. I also can't seem to get the scanner to log IAC counts or the commanded RPM either despite adding the PID to the interface. Same story with oil pressure and system voltage but those are side questions.
Any suggestions?
