'93 LT1 ECM issues - anyone have a spare?
I'm wondering if I have ECM issues. I have an injector driver fault that's just flashing intermittently, on both banks. It shows up in TunerPro RT.
I also have a part throttle "surge" that I can't seem to get rid of either. Kind of thinking the surge and the injector driver fault could maybe be related.
Not sure how to really diagnose it, other than swap an ECM in.
Car has done this from the beginning of the swap. It has a 224/224 Schneider cam, not that crazy. I'm actually running a few degrees less timing than a stock LT1 at this point. With the more aggressive cam, it should have in theory needed a bit more timing due to less DCR.
Anyway, if I could find a '93 ECM at a decent price, I'd probably buy one. So, anyone out there got one they wanna sell?
