ecu engine swap questions
I searched but can't find an answer that is this basic. I know party of the wiring harness connects to the ecu. Where does the other part connect to? Why do people have to modify wiring harnesses like on a h22 in a prelude, can't you just use the prelude wiring harness and ecu or the original civic wiring harness and ecu? Or like putting a b16a2 in a 92-95 ex couldn't you just use the original p28 or the jdm ecu? Another question I have is what is the difference between obd0, obd1, and obd2? Why cant you put an obd0 in an obd1 car or and obd2 in a obd1 etc without modifications? I'm just confused on what happens to the ecu in swaps.

Re: ecu engine swap questions (importpower)
in some cases you can use the same computer like in the 92-95 cars you can use the p28 but fuel maps, vtec crossover, and lower rev limiter is what makes people change ecu's out. but if you put in a b-series computer you have to wire some things such as knock sensors ect...

Re: ecu engine swap questions (saleensolution)
So if i'm going f/i and i'm going to have to chip it anyway the ecu, couldn't I just burn a b16a base rom on my p28? Will the engine not run properly without the extra sensors?
