i own a 1990 4 door integra and swapped in a Japanese B16A into my car. I looked up my ECU and came back as PR3-J00, JDM integra and EF 8/9. I was wondering if that is the right ECU for my motor because I am only redlining at 7500, and not 8000 like suppose to.

 

Hmm i think stock they are like that on the older models, if you get it chipped for 8200 then that be your best bet, but this if everything is fine with your car and no codes are being thrown.
