Ecu/Harness Question

[aroche25]

I just received a 1995 Harness with 1995 na ecu that was bought online. I was wondering if I am able to use the 95' ecu on my 90' na after the harness has been changed? My guess is no, but im wondering why not. Also what problems would a 95' harness address vs a 90'?

Thanks I searched here and couldn't find anything about this and tt.net is down

Yes you can run a 95 ECU and harness on a 90. You will have to change the injectors at the least and maybe the CAS and PTU, depending if the recalls/TSBs were done. I'm not sure about other sensors but I'm fairly certain you should be safe after doing those things I mentioned. Good thing about 95 ECU/Harness/Setup is new style electronics (injectors, etc.). Bad thing, some 95 ECUs (not sure which exactly) are physically un-chippable, so if you are looking to upgrade later I'd consider going with a 94 (make sure its chippable, still 16 bit but has a place for the daughter board) and uses new style electronics. BTW, there was a thread about 2 weeks ago where I discussed this exact thing, I think I need to start holding "internet search query term selection" seminars because I never have problems finding what I need you just gotta know what to type into the search window. Hope this helps.

Yeah I saw something about the harness too but not the ecu. Thanks for explaining it though. Also I didn't want to bump a older thread because sometimes it freaks everyone out.
