i searched but couldn't find anything. what will happen if i plug the p72 obd1 ecu from my 95 gsr into my girlfriend's stock 94 accord ex coupe? (also a 5 speed)
i know people use different than stock ecu's all the time for performance gain. what happens if i use the gsr ecu on my girlfriend's car? i'm asking cuz i don't know so please don't flame me too bad.

 

anybody?

 

why would you want to do that? i dont think your going to gain anything at all, you will probably loose power by swapping.

the accord has a 2.2l sohc (f22b1) engine with a 6250 redline vs the integra 1.8l dohc vtec engine with a 8100 redline.

i dont think the p72 ecu will work very good. the fuel and timing maps are probably going to much different.

 

It'll run fine and throw a code for knock sensor.... damn, I was warned that this would be a stupid question, but oh well, damage already done.

Edit: Tons of H22 swapped accords run the P72 to avoid EGR codes cuz they are too dumb to figure out how to do a motorswap without throwing codes.

 

oh ok. well that was the answer i was looking for. and besides, how in the hell am i supposed to know that?! i mean really... thanks to all who responded.
