LB7 ECM Read issues

[GMC-2002-Dmax]

The reason I'd want to load a new OS is I have an 01 ECM, but if someone had say an 03 or 04 LB7 and I was going to let them try a tune or something, best bet would be to flash their OS into my ECM, modify it and let them run that instead of trying to run with the 01 OS in their 03 or 04 truck.

I have full flashed many, many 2001 ECM's with either 2002-2004 OS without any issue.

I will not attempt reverting to a 2001 OS even with a 2001 ECM once the original OS is overwritten.

All of my 2001 customers run a 2002 OS and the computers are from 2001-2004 and nobody has issues.

What caused the fried ECM? I am getting the same readings on the 01 lb7 I am trying to read. I will try to pull the file
