Ecm

are all OBDI computers compatible with all hondas?? i mean if i have a P28 like in 94 EX civic, will it work in a 94 and up teg? will the vtec engage even if it is an SOHC engine or DOHC? i know that if it works the redline should be the one that the computer has programed on and the vtec engagin at the programed RPM, but will it work?

question should be......................why are you switching ecus? timing and fuel maps are different on all ecus. that is what you need to keep in your mind. will it work..................yes. will the AFRs be be different..............yes.

just curius, cause some guy toldme that i should put a P30 OBDI so the car would run faster, and when i was cheking to see how true this i found that theres an OBDI P72 and mines an OBDII P72.
