Ok, I believe this PCM had an EFI COS installed Previously. I just had it flashed through a GM dealer with current software and OEM tool. Then read it out with EFI live. I deleted the VIN from the image for personal reasons.

I am just curious why the Calibration ID and BCC lines don't get corrected when Flashed with OE tool???

I think it's possible that the software version used by the GM dealer for the flash did not include the specific updates to the Calibration ID and BCC lines.
