Admittedly I'm new to all this, but I searched away and couldn't find a solution so I figured I'd post.
When I load Tune v7.5 and read an ECM I get the "Details" window on the right side of the screen. Under the "Calibration" tab it lists the Segment, ID, and Checksum. The only problem is the literature I have from GM shows a CVN and not a Checksum.
I thought these were different names for the same value, but apparently not! The checksum is a hex number that is very long (more digits) than the CVNs. So, now the question: how do I convert the Checksum values to CVN values?
Thanks!
