Anyone have a 4.3 Vortec V6?

[GAMEOVER]

This problem is only for my 1998 Vortec.

For the life of me, I still can't figure out why my data logs won't link to my tune file. When I highlight a section in a data log it won't automatically link to the tune file....Even if I make a Timing MAP in the Scan tool, the info doesn't correspond/or is way off with the info in the tune file...sometimes off by like 10 degrees at certain points.

The only thing I can think of is the warning I get when I open my Tune file and then open a data log i get this warning: "Vin mismatch was detected between Scan Tool(Vin#123456789) and Tune Tool(Vin#NA)....Vin numbers are from 2 different vehicle's"...The tune tool will not let me save my Vin# for some reason, always shows NA
