Which ECU do I have?

Alright… I used the “search” button first, so don’t yell at me.

I have a '90 GS 5-speed. Which ECU do I have or how do I find out?

Please help the new girl.

Yep, you have an NON-OBD PR4 ECU. The PR4 came in a NON-OBD and an OBD-1 configuration…

It is, I misread the year in her post… For some reason I thought it said 93…
The 90-91 tegs have the NON-OBD PR4 and the 92-93 tegs have the OBD-1 PR4…
I will go edit my post…
