Hello I have a Celica GT4-91.
I want to install a Apexi power fc "mr2 gen3" and therefore need the pin diagram on my ecu. So I can convert my ecu to work with the gen 3 mr2 3sgte.

I know guy i know have the diagram fore a 91 mr2 turbo euro/uk spec.. But I have heard that there is some difference.

Hey Amby from Sweden.

I wasn't aware there was a European spec ECU. I thought there were only two, the aggressive JDM and the normal one?

I have search on http://www.toyodiy.com/forum/
I have found 3 different part nr on the ST185
89661-20770
89661-2B300
89661-2B320

And I found this http://www.ts-ogn.no/files/3sgte-ecu-pinout.htm
But my ecu code isent listed...



I belive ther is one early euro 89-91 and one late 91-93 ST185 ecu too.
My being the early 89-91 ecu.

Yeah I did a quick search and only found diagrams for the 92-93.

You could try sending a private message to Meurz. He's from Europe and knows his shit about these cars, maybe he can point you in the right direction?

Sorry I can't be more help.

AFAIK, the pin-out of your ECU is the same as the UK model 89661-20750 or 89661-20751...

89661-20750 ST185 - 10/1989-03/1990
89661-20751 ST185 - 03/1990-08/1991

did you try looking here:

In the Master sheet there is a list of most ECU Pin-outs by P/N
