whats is a pr4 ecu and a pg7 ecu out of? i know they are from ealry 90's tegs, but i don't know which one runs which motor.

which of the 2 ecus has a 7200 rpm rev limit? i know one has a lower rev limit like 6500 or 6800. this the one i dont want. i did a search and got one thread that was just a sale thread and it didnt say what i needed to know.

thanks

 

pr4 is out of an Integra LS, b18a1

wasnt sure about the pg7 so i did a quick search and this is what i found:
pg7 is out of 88-89 Integra, used for dohc zc swaps, and it looks like the pg7 has a ~7500 revlimit according to some people

 

actually PR4 is both 90-91 teg and 92-93 teg. just that the 92-93 has OBD2 plugs on it and the 90-91 has OBD0 plugs. they both have the same rev limit of 7200.

I think you mean the 92-93 tegs have obd1 plugs. Obd2 didnt come out until 1996.

 

ok well im asking cause i bought a pr4 ecu before and it only reved to like 6500 or 6800. i need to know which one will rev to 7200. ?
