Need 6.0 4l80e 4x2 DBC 12212156 OS

Been searching everywhere but can’t find a bin file anywhere. Currently have 2001 12202088 OS and I’m having an issue with the fans always on no matter what. Made new relay harness for fans and checked wiring a dozen times. Did some research and heard it has to do with OS and to try a 2002 12212156 bin. Only bins I can find are 4x4 or dbw.

I have a stock bin that I'm using. it's for a 1mb pcm (12586243 is the pcm I'm using with 12587603 OS) - The bin is completely stock from GM TIS website. Flashed it to PCM then saved .bin to my hard drive using PCM Hammer. It's for a 04 CHEVY EXPRESS 3500, 6.0, DBC, 4L80E. VIN #1GNHG39U941126032. It will run the electric fans.

Can I get a copy of that bin plz ?

I's like a copy of that '04 stock .bin for my archives too. OP, the file he is posting is for a 1mb PCM, yours is a 512K PCM. If you have no luck finding today, I will build you a file after I know a few more details. I have a grad party to get to shortly so I can't help until tomorrow.
