AEM FIC fight for turbo!!!

Awesome Scott, I didn't know that about checking grounds. I guess I'll use that method to check as much as I can. As far as plug gap I re-gapped down from .032 to .029.

I'm almost positive it has something to do with the ECU fighting the FIC or something like that but I have very limited knowledge on how the FIC works and how the ECU responds. I just don't see it being an existing issue with my car since the car runs smooth and fine even at idle when the FIC is bypassed.

If it runs fine with the FIC bypassed, it would then point more to an issue with the FIC or the harness.

For fuel control (which would be the most likely FIC behavior to cause misfires) the FIC monitors the signals from the ECM and adjusts the injector pulse length based on the map (making the injector squirt for longer, shorter or the same amount of time as the ECM is commanding).

If you load a blank map (all zeros) and the problem still remains, then the problem is likely hardware (FIC or Harness). If the problem stops with the zeroed map, then the issue is map related.

you mentioned a gas smell. make sure the injector cushions are seated properly or you will have misfire. Do you have a lightweight flywheel? that will cause false misfire codes.
