does anyone know why the CVNs on TIS (under complete history) are all different from the checksums? this (http://www.pcmperformance.com/programming_files/2G1FP32GX22120917.zip) factory file for example.

The CVN's and Checksums are two different attributes...

for E38 boxes say, does anyone know if GM tech2 checks only the CVNs, or both CVNs and checksum?
