Here's the stock tune file I downloaded from my 2004 GMC Sierra 1500 4x4 with the LM7 5.3 and 4l60E with OS 12587603.
04 Chevy 1500 4x2 LM7 12606960
Flashed with TIS2000 and read with PCM Hammer
2004 Hummer LQ4 6.0 4l65e 12587603
2004 Escalade LQ9 6.0 4l60e 12587603
Does anyone have a bin file for a 2004 chevy express van operating system 12587603?
I have no history with this bin file, just one in my archives. Hope it works for you :)

Anyone have a copy of 12583506 OS for p59 pcm. I guess it is not the latest revision and it is really hard to get one.
Hello,
Not sure, but I think you have been advised in several places to abandon chasing XDF files that don't exist for some BIN's. Why such a strong attraction for a 12585950 XDF? You could have already prepared a suitable BIN for which we have richly provisioned XDF files. Its a few hours of work to edit an unmodified BIN into what you need but after that, you are good to go . . . write it to your PCM.

i wasnt sure if i could change to another one being this is in my stock daily driver 2004 suburban and not a swap
Get a junk yard PCM and give 7603 a try - don't risk the installed PCM in your vehicle. What exactly is wrong with the PCM in your daily driver 2004 Suburban? Do you have strong emissions control laws where you live?
What are the colors of your PCM connectors? Red/blue? Or blue/green?

Hello Corey,
Ok, if you can't answer simple questions, you force me to derive the answers. The connectors are blue/green because you have a 1 megabyte operating system.
After that, I'm giving up because of your lack of response to post #29. We can't help you if you don't respond with answers to our questions.
