Im going to go get a "new" ecu from LKQ today, and there are several choices. Are any better than any others? I am running a 2002 5.3/4L60E out of a silverado.
2002 Suburban
2002 Tahoe
2002 Silverado
2002 Yukon XL1500
2002 Escalade
2000 Silverado 2500
Do any of these have benefits over the others?
Nope they should all be the same...the 2500hd wont work though cause it's prob a 80e trans file
You need PCM number 12200411. It doesn't matter what it is out of. You will have to have it tuned anyway.

In the trail blazer ss pcm is ready for boost. That could be a plus.

You really should have your factory program loaded into the PCM by a TechII or something similar. Just writing over what is in there with HPTuner software won't be the same as a new load. It won't matter if it had a 80e in it that way, just get the 411 PCM and you'll be good to go.
How do you know if the pcm are able to fit or not.
there will be a label on the PCM and the part number on the PCM will end with 411. It will also have labels on the connectors that say red on one side and blue on the other. It embossed into the connector on the PCM if I remember correctly.
not embossed, just stamped, but yeah, red and blue.
same question for a 6.0L 2005 LQ9?
Any PCM from a 03-06 truck will work, but as stated, you will need to have it flashed for your truck.Quote:
