alright guys i'm going to pickup an ecm to replace mine since my tuner thinks it's bad. i don't want to get a reman from the yard but since gm's is reman and 3 times the price i figure what do i have to loose.

what can i do to insure that the ecm i get is good and i'm not just swapping junk for junk?

If they can start and run the engine along with using a scan tool on it would help. Other then that if the car is bashed and not around the ECM that means at least it was probably a running vehicle.

well the yards around me typically have them just laying around as they remove them from the cars when the come in i suppose???

all the places have offered me a return/exchange setup but i'm just hoping to gain a little knowledge on them in general so i would know what to look for beyond the obvious when i pick it up. i hate dealing with used electronics when its something so important.

I've had better luck with ecms out of a junkyard then the supposedly rebuilt units. The GM remanufactured ones are OK, but the parts house ones, have a poor track record with me.

If the SES light acts right, chances are the ecm is OK.

Once you get it running right, invest in a spare ecm, and test it in car, and then put it on a shelf. With some hunting, they can be bought for very little.

thanks for the advice. found a few for $20 out of a camaro and beretta that worked well. much better then paying 100+ for one when they aren't even new.

called one place that wanted 140 and then said they couldn't have it til noon the next day as they didn't have a parts guy. (probably planned to pick one up from the yard as well).


either way thanks!
