Engine electronic Problem
Hey Everyone i looked up my industrial 2002 Cummins on Cummins Quick Serve and it is in fact a standard output and not a high-output. However, I have a highout put ECM and my engine runs funny at an idle after i press the pedal. I loaded a video of its symptoms. Is this what you guys have seen when there is a high out put ecm on a standard engine without the high compression pistons, and different vp44?

Interesting... any codes? I know for a fact HO and SO vp44's can be swapped back and forth without side effects. I also know the compression ratios are different in the 2 and who the hell knows how the ecm's vary, I doubt anybody on here will know for sure, but the best thing I can think of is get an SO ecm.

Hey Empty Wallet,
Thanks for the help man. Only code thrown is P0341 about the cam sensor and replaced it and code doesn't go away. I might bypass harness and solder directly to the wire coming off ECM i have a diagram and I will continuity test it to make sure i have the right one. I think this could be an APPS issue also making the idle validation go from throttle to idle throttle to idle. I believe i will for sure get it re-flashed so later down the road i wont have any problems with everything matching.
