Hello everyone, I'm new to the forum. I enjoyed EFI live for a while with my Duramax and now trying on my Cummins. I purchased another 2350B from a 2015 with autotrans and swapped into my truck desiring not to mess with the original ECM. I programmed a 2017 stock tune. The good news is after the reprogram the P R N D lights went away so it appears the ECM thinks it's now in a manual transmission truck. The bad news is that the engine will only run about 3 seconds then die upon starting, the key won't come out, and I pulled the neg. battery connections while I seek wisdom.
