Hey Everyone,
The pieces of the puzzle:
E67 ECM Service# 12678513 from a 2012 CTSV auto
6l80e from a 2017 Silverado
I am working on getting my swap up and running and wanted to verify my OS compatibility. I am running an E67 ECM with OS 12653238 and a TCM with OS 24276638. I have seen some posts stating the 2017+ 6L80's require an E92A ECM?
I definitely bit off more than I could chew with this endeavor and would appreciate any insight.
I would check the hardware number on the TCM, and if it's compatible, just use the known-matching 2012 CTS-V trans OS.
Is the hardware number anywhere software wise, or do I need to drop the pan and valve body to check?Quote:

Thanks, Squirrel.
Do you know the VINs for the two donor vehicles?
This is not definitive, but rather an indicator that it's worth investigating the hardware properly. Running the truck VIN (on a site with the complete GM database, not a quickie like rockauto) would be a good start, and if there's only one number and no ambiguity, I'd probably say it's safe to just try flashing it.

I don't have the trucks VIN unfortunately.
Does the T43 brick like an ECM if an unsupported OS is written to it?
Drop the pan. Or I'm fairly sure a Tech2/MDI can read that kind of module information. HP Tuners wasn't really ever meant to be a replacement for a basic manufacturer-supported scan tool.
I've over written T43's a bunch of times with no issues. Thats not saying there might be one one day.. but whatever you do seems reversible.Quote:
