ECM Questions.

[RyanEricW]

I recently obtained a 1990 Eagle Talon TSI AWD, it was stripped and had quite a few things done to it, but the problem is the car is in peices. I have to put it back together.
I plan on putting the 4g63 in and turbo back in the car, like it was originally. And I plan on putting the 5-speed manual in.
Here's the issue, it came with two different ECM's, and seems like 4 wiring harnasses. (2 engine bay, 2 interior)

The computers that came with the car, I ended up looking up the part numbers, and got the information I needed, except I kinda guessed at if it was for a auto or manual trans.
On the bottom right of the casing for the ECM, one has a "A", and one has an "M", so I kinda just figured it meant auto or manual. Right or wrong?
Second question is, since I plan on going manual trans turbo awd, will the MD12-8625 work?
It seems like it's for automatic only, but I'm not sure if that would play into any drivability issues once I get the car running. I'd be prepared to probably get some MIL's, since the automatic isn't there, but I could ignore that until I could find a proper ECM.

MD16-6255
- Eclipse 2.0 DOHC
- Non-Turbo
- Manual Trans

MD12-8625
- Eclipse 2.0 DOHC
- Turbo
- Automatic

Thanks

The A and M don't directly relate to the transmission type. It's all in the part number.

MD128625 is for a 1990 Federal Turbo Manual FWD car but will work with in an AWD.
MD166255 is for a 1991/92 Federal N/T FWD car, Automatic or Manual.

There weren't any turbo automatics in 1990 for you won't find any ECUs for them. There is a difference in the 1G turbo car ECU's because of the engine differences between the automatic and manual cars.

Here is my list of what ECUs's came in what cars. Eclipse Talon Laser Galant 3000GT Stealth ECU ID Reference
