View Full Version : Power FC interchangable?

04-15-2004, 10:07 PM
I have a SR20DET s13 RPS 180sx Blacktop Power FC, early model (94-96)...I've been told this ecu can work with the SR20DET redtop engines, but a few pin changes are required. Does anyone the exact pins that will be needed to change. I believe the rpm pins are slightly different and need to be changed...what else?
Any help would be greatly appreciated.

It should work without any pin swapping. Just plug in and go. Early model blacktop E5 ecus are interchanable with the earlier #62 Redtop ecus. The only thing you may or may not have to do is purchause the appropriate EGO sensor. It's my understanding that if you run the E5 ecu w/ a redtop EGO sensor your fuel economy goes to crap. Don't know if this is true with the PFC though.

from my experience, the only (s13 sr)ecu that is different as far as pins go, is the late model s13 blacktop... the redtop ecus and the early blacktop ecus have always worked fine with either form me...
btw, changing the pins on the late model isnt very hard, only a few pins that if i rememder correctly have to do with the injectors and maybe one or two others... i probably still have my notes from the first time i figured it out, just have to look through a mess of crap...

ps. vosko doesnt know [censored]... this isnt nopistons, everything he says here is just watered down info he hears from other people... http://forums.freshalloy.com/images/graemlins/wink.gif hahaha, i love you tubby... http://forums.freshalloy.com/images/graemlins/grin.gif
