so i was driving around last night and i pushed my car to WOT and randomly the ecu clicked off and my car stopped getting fuel. all indicator lights came on and there was no power. i took the car out of gear, revved it, and put it back in gear. i could drive for about 30 seconds before it happened again. i have my glove box off for cleaning, so i disconnected the ecu, check out the harnesses, and reconnected it. problem solved. then today, the same thing happened. the ecu appears to be fine and the caps do not look like they have damage to them. suggestions?

<- is stupid...i was looking at the wrong electrical unit. i took what is actually the ECU out and noticed first off the black stains on the inside of the ECU cover. next, 3 components are completely fried. my guess is when my alternator blew, so did these. they aren't caps, but i think it can be repaired. can anyone help with this? the are long and thin black components located at the top of the ECU if the harnesses are on the left.

right where it says "100uF" is where the damage is, and below that. do i need to replace it? i would rather not mess with it if i can just replace the entire unit. anyone have one kicking around? averages prices?

It's clear your ECU needs attention anyway, but have you checked your battery?

I guess it is the shock of all the mad powwa, but at least once a year or so, my battery connections come loose on me.

Just a few months ago, my car was shutting off and turning back on. I knew my caps were replaced, so I checked the battery first thing. Yup, the negative likes to get loose alot. I had the same problem with my Talon too.

I've learned to just check the connection every time I do a oil change.

Anyone else get this?

I see now, I misunderstood, your's is damaged where the lettering that says "100uF" is, not where the 100uF is. That is the fuel injector driver circuitry.
I'll still buy it. Original GVR-4 ECU's are hard to come by. Let me know.
Or. is it something like this?:

That is one of the ISC drivers smoked in that picture. This is usually caused eitehr by 1)a shorted ISC, 2) acid under the 47uF cap, or 3)water in the ISC from the FIAC leaking.

Pay very close attention to what Jeff just said. If it was 1 or 3 of what he said, your Problem will remain even though you have a new computer. Then your new computer becomes trash like your old one. Check the ISC for a short or water in it. Do a search for ISC and you should find coverage of these problems.

Chris,
You can tell if it is for a Turbo car or not by whether it has that large, elevated PC board in the bottom right corner, with the black donut in the middle. That is the knock sensor board. If you don't have the chip in the top right corner, that just means it is a non-EPROM board, so you can't play with any of my free chips. What is the actual model and part numbers on the label? And, does the number stamped in black on the white connectors match the last 4 digits of the model number? From the info on the VAQ you should be able to tell exactly what year and type car it came from.
By the way, I just Paypal'd you for your old ECU.

i have 2 ecu's. both are missing the top most 2 chips on the right side, and one is missing a white board under the CAPS. i don't have an afc to help with fuel flow, so what do i do? i thought that 91-94 turbo awd ecu's will work perfectly. was i wrong?

i put back in the ecu i bought and revved it until the idle started to improve, but then the ecu started smoking and my ISC caps were blown again. you mentioned something about a shorted ISC? please help me troubleshoot this, i just wasted a $90 ecu...
