got me a new PCM with a tune already installed, now I would like to compare the files from my old PCM with the files on the new one, even though it has my VIN programmed in, it says "File does not have same Segment 1 ID"
is there a fix for this problem or can LS1edit be tricked in any other way?

 

The operating systems are different between the 2. That is not an option to use ls1edit to view the difference with it.
