i have a 91 rs (no power anything) and i have no ecu right now, cause i sent it out. I am looking to swap another one in for now, and what i can get is a 90 teg computer. It has power everything tho... will this mess anything up on my car, or can i just swap it in and have everything stay the same? thanks in advance!

 

It will work fine ECU has nothing to do with Power anything.

 

just look for a 90-91 obd 0 pr4 ecu (5 speed) assuming your car is a 5 speed. Doesnt matter if its off of a ls/gs/rs....same motor in all of the tegs, which means same ecu in all of the tegs.

 

ok i installed the ecu, but now the car is idling really rough and the check engine light is on, is this normal?

 

whats the code on the ecu your using? 37820-??-????

 

sounds like a dumb question, but how do you check the code that the ecu is throwing?

 

ok, the actual code of the ecu is 37820-pr4-ao2, if that's what you were looking for.

 

sounds to me like the junkyard that sold me the ecu sucks . The ecu is faulty in that the ecu is throwing code 13, atmospheric pressure sensor. I was reading and you are supposed to replace the entire ecu with this problem. can i still drive the car?

 

90 and 91 Integra ECU's are different. 90 has an external PA sensor and 91 has an internal one.

 

can i drive?
