The layout is alot different and uses new names for the VCM scanner. I like a few things they did in the scanner to make it easier to follow where you are while playing back a scan. The new channels display is kinda nice and I'm really hoping the scanner is as fast as they claim, it seemed to bog down sometimes during scanning in my Silverado. The grand prix's use a much dumber PCM so I didn't have this issue.
And I can now tune the VE tables like a GEN 3 V8 computer if I wish too on mine. That was something only a secondary software could do before they started beta testing this a few months ago.
I don't think anything grand prix related has changed, maybe on the V8 side. But the 3800 computers have been out of the game for a long long time and I havent seen anything updated on them in many years.
