ZL1 Colorado
#72
have you tried to source an actual zl1 ecm? i know that you flashed the zl1 file onto it, but hpt doesn't give 100% ecm access. there maybe something in the backside of the ecm not giving the green light.

I just tried the GMPP ECM. Does the same thing. Also cool was the fact that after I licensed the ECM to put a VIN in it to make it start, it keeps requesting that I license it again in order to write any more calibrations to it.
I have considered that. **** it, let this guy pay more...
