1988 / LA3 Manual ECU

Greetings all,  does anyone have a spare ECU from a 1988 Manual TC?  Looking for the OEM all-gears-boosted profile vs. the 1987 cars.   I know you can just add a bypass valve and such but I'm still going for OEM at the moment... so if you upgraded to an aftermarket or have a spare you're not using and can sell please LMK... thank you!

Um,,, I do. What are they worth?

I went out to the shop and found it, not sure you'll want it because it's a reman. IDK if that's a bad thing or good, it may have some updates/upgrades that weren't in existence when the factory unit went in. I'm owner #3 of this car and I bought it in 06, and I didn't own it when this ecu went in. I can verify it works fine in an 88 5-spd car.

   

   

Wow, thanks for that info. Haven't seen a reman ECU before; is that by FoMoCo or someone else? The solenoid warning is interesting: sensible advise to be sure the root cause of an ECU fry is found, yet it hardly inspires confidence (why wouldn't NOS/OEM ECU's carry the same warning?)

I'm still interested but as for price, I've seen OEM FoMoCo EEC-IV turbo ECU's of all types for around ~$200 on ebay lately, but for that I'd be more inclined to open the aftermarket ECU/mod rabbithole. Old/archived posts suggest OEM were significantly cheaper "amongst enthusiasts" here even just a few years ago... obviously that's what I'm hoping for but I respect if you're on the higher end. PM me if you like and hopefully we can hash a deal. I have some random spare parts and can even rebuild/clean taillights if you're looking. Thanks again.

I have no idea of its origin, I ASSumed it was a warranty thing so it would be a FOMOCO unit. Wheres Professor Korn when you need him?
$200?!? WOW!!! That's 2X more than I figured it was worth. I'll PM you in a bit, maybe someone will chime in on the remanned ecu subject.

Reman ECUs are not at all uncommon and there a number of companies out there that do it now. On these older units what ends up happening is a capacitor leaks, diode gets burned, maybe a connection gets corroded or a circuit on the board gets burned. All these reman places do it solder in a new capacitor or diode or solder in a small wire to replace the burnt circuit. They "test" them, however they do it, and send them out the door. In my mind you're going from having a non-functional ECM to a functional ECM, but I do not consider them like new.

I've used a few in the past on various vehicles and don't recall having an issue with them. I've never used on in a performance situation though, only to repair a grocery getter.

Thanks, I figured that was likely the rebuild process. I'm well versed in replacing such components on pinball boards and other electronics - all the way to repairing alkaline damage and traces and whatnot. I recapped my Tripminder to fix it, and inspected my radios, EQs, etc for same. Previously opened up the ECU from my V6 parts car and was (pleasantly) surprised by the coating on all components which seems to preserve them - and makes the solenoid / failure mode warning more sensible. So as long as the ROMs in the ECU pass muster, component repairs are almost DIY prescriptive. Checking the ROMs via testing is the key for certified refurbishers, "however they do it" as you say. Either way I'm more curious as to failure modes and rates.
