Resolved 1992 Talon TSi ECU question

[joey]

Hi guys, so I've been out of the game for a while now but I'm trying to get my Talon running again. She's been sitting for about 6 yrs in a garage. I went out to work on it to get her up and running and pulled the ECU. The ECU has corrosion and black spots where it looks like its fried some caps and resistors. It's a 92 AWD with 6/4 combo and ABS.

My question is what kind of ECU can I put in it that will work? Does ABS matter? Any help would be appreciated. Thanks.

Can you post pics of the ecu?

I will def try when I get home I'm at work at the moment.

Any 1g turbo 91-94 either 5spd or auto. Match what you have. 90 can be used but there are a few wiring differences.

You might want to look for a good EPROM ECU if you plan to modify the car.

See that's the thing, the car does have a bit done to it. List is as follows, Evo3 16g turbo, 680cc injectors, ported exhaust mani, 3in turbo back, Walbro 255 I think, adjustable FPR, Apexi AFC, Dejon intake, and hard pipes, bigger throttle body elbow, open wastegate, COP setup and also a stage 3 Spec clutch.

The problem is I am on limited funds, so I am trying to fix the problems it has and get it running good without spending $2000. What do you think my options are?

I also have a MAF translator pro but it is not hooked up. I don't know if I want to hook it up yet since I cant really find anyone who has one or tuned a DSM with one.

The AFC will let you adjust for the injectors. 680cc's are just about as big as you can go before the timing gets too far off due to the way the AFC lies to the ECU about airflow.
