Yep...I was just curious, it would be nice to have the ability to modify 12212156 os .bin files using TunerPro though.

EFILive shows incorrect on transmission calibration, and system after saving...

Dimented's .xdf did correctly calculate (fix) the bad checksum for system section, even though it isn't correct for 12212156 os.
I don't have the plugin installed. I did not look @ the .xdf...

I also tried using these, just a VATS change results in an incorrect checksum.
