Hello guys, long time no talk. I'm doing some tuning on a new '94-95 OBD1 8051 LT1 vehicle I bought and I thought I'd ask - anyone know why the LT1 injector faults are turned off in the ECM switches menu? I'm using TunerCat BTW.

i've seen a few applications that have an injector fault DTC.... most, if not all, were disabled in factory calibrations. they simply checked O2 sensor voltage when in DFCO, if the signal didn't go and stay full lean, it was assumed an injector was still spraying and triggered the SES.
not all applications may be like this, but that is the one i remember.
