does anybody have an idea as to where I can get my ECU rebuilt (86 GL10) and are the automatics different form the manual tranny

I think you can get service done by Python. I think there is a dirfference between manuals and autos, also turbos. I have fixed some in the past also. What is the trouble with yours?

No difference in the ECUs for auto or manual

MPFI 85-86 ALL ECU's (turbo and non, cal and non) are the same they have black connectors - different grounding on the wiring harness desigates turbo/non mt/at and cal/49 state

SPFI 86-94 ALL ECU's are interchangeable period they have yellow connectors - however some early ones had error issues (I know 1986 ones are in the family) with the CAS and other stuff, newer is better try to find a late MECF-## code, I am running one that is MECF-22

!!Just wanted to clear that up!!

1987 and later MPFI ECU's are probably different b/c the FI system is different, but beyond that I don't know I haven't messed with anything that new

Just find one in the junkyard, it's much cheaper and ECU's usually work or don't - there is not much grey space there

There is one in my local yard from an 89. I can send it for $45 shipped. Lmdew@hotmail.com

Thanks for that great amount of info...I am strong believer in obtaining parts form the auto wreckers...driving an 86 turbo puts a lot of limitiation in finding one from the yard
