The only other time I have heard of a 34 ecu in a stage a was in a thread in forced induction. A guy from the UK had it done, and the trans wouldn't shift properly. And heaps of power was missing"
I can't remember exactly but the title had something to do with t2 turbo,as apparently that's what his tuner fitted....
Anyway I'm predicting this will be way harder than you think. 4bidn1 has done a neo conversion so would know a thing or two about the neo Ecu's hidden traps.
