ECU ID help

[Baron4406]

Ok I'm really scratching my head here, I took the ECU out of my 1993 Talon AWD to sell it since its an non-eprom and I need an eprom to go speed density. So I'm looking at the numbers and I'm trying to track down what it came out of, there is no MD number on it because it was remanufactured. There is just a "E2T" numer.....so I looked the number up and it came out to be from a 1990 Eagle Summit non-turbo. WTF??? I mean my car ran fine on this, it registered codes, registered knock, looked fine on my logger. So you think the case could have been swapped? The ECU with the cover off looks exactly like the eprom unit I just bought minus the Eprom of course. What the heck?

What is the E2TXXXX number? Does it match the numbers on the white connector inside the ECU?

Probably just a different case, if you could register knock. Open it up and post a pic of the board.

so I take it that you no longer need my Eprom ECU? Also if it ran fine in your car than I would imagne the cover has just been replace. I'm pretty sure a 90 summit would not run your car at all. It may start and idle(like crap) but you would not be able to drive for many reasons.

Ok I have a '90 Eprom here so I opened it up and compared the two, I noticed the last 4 numbers of the "E2T" number are written on the white connector....ah success! Its a ECU from a 06/90 - 06/92 Federal M/T.....which is why it worked perfectly in my car . I have this ECU for sale, and I didnt wanna rip anyone off.

So there is a lesson, especially if the ECU has been rebuilt it may have a cover swapped from a car that isn't even a T/E/L

Absolutely. It's a really big problem, particularly for 1G guys. Salvage yards will routinely open up 10 ECUs at once to document what's inside each and then they seem to randomly replace the cases! It's crazy.

And it sometimes puts us in a hard spot when someone sends us an ECU out of their turbo DSM that has a turbo DSM EPROM case and we have to break the news to them that the board inside is actually from a non-turbo, non-EPROM ECU... There has been at least once instance where the customer seriously accused us of trying to swap boards on him.

So, yeah, it definitely happens and fairly regularly too.
