Recently purchased b18a from a local salvage yard, motor ,5 speed cable tranny, ecu, and axles, my question is , the numbers on the ecu , anyone got any info on what they should be, just making sure no one switched it as they removed it from the car, it was out of a 91 integra 2door..
thanx

 

I can't exactly remember what it might be. There should be a forum on here about that. If you are planning on using a Hondata system, go ahead and step your ECU up to a better one, or just AEM.

 

pr4 obdo

edit: out of 90-91 teg so u should b fine

 

Yup OBD0 integra ecu is coded PR4

 

thanx thats what is says, gotta make sure its all on the up and up...
