so i have my st185 3ngine in an st165 body, running of of an st165 ecu. i came across a craigslist ad for 2 ecus. one 2nd and one 3rd gen ecu from mr2s. they were selling them for 120 each and i was seriously intrigued. is the mr2s 3sgte ecu exactly the same as the celicas 3sgte ecu? because i have the cash to do it now. itll put me one step closer to getting this car running nice and smooth. feedback feedback feedback! :banana:

Depends on the revision.

The 90-91 st185 and sw20 ecus are the same. The 92-93 sw20 has a couple different wires pinned differently but you can repin your harness and it will work just fine. Both ecus will work.
