Tried a known good ECU yesterday and it didnt studder/backfire at all.
BUT the funny thing is that I did the swap in the afternoon and was driving all morning and the car was mostly well behaved with my ECU. I could get a slight studder/backfire if I tryed but it was slight. Today driving around with my ECU the stumbling was very strong.
So im not possitive but 99% sure my ecu is messed up, even though I changed caps a year ago and all was fine since then. I am pretty sure that somehow a malfuntioning LT1 mass burnt a hole in my ECU fuel map @ 2700rpm.
