What program was in the old ECM and what program is in the ECM you are using now? You can't just slap any old ECM on your engine and expect it to be right. You need the proper template flashed in for the jakes,cruise,etc. to work, and then you need the proper engine program thats compatible with the hardware you have.

I didn’t just slap in anything. Both were programmed by a mechanic. I personally don’t know what program is in it however. I will have to have someone check
