93 atx ecu
I don't have one to sell, but can give you some advice having replaced the same ECU in my 93 626:
- The last letter of the part number corresponds to the VIN range. Since these old ECUs could not be flashed, they had to make a different ECU when they wanted to change anything. When I replaced mine, I just got the last one (ended in a "G" I think) and it worked fine, even though my original ECU had a different letter at the end.
- These ECUs go bad when one or more of the capacitors leak. There are people who fix them. I tried one and it only worked for a few months--though the guy did give me my money back.
- I got a used one for about $20 from car-part.com
- When you get a new one, be sure to open it up and inspect the capacitors on the board. If you see any leakage--it looks like drops of cola--don't use it; get another. Google "leaking capacitor on mitsubishi ecu" for images.
