Hey everyone. I have a 2005 ls1 computer that we've been trying to swap the vin over in. We have tried in both the tuner and the scanner both with no luck. The rest of the info in the tune flashes fine, except the vin, that always reverts back. Both in the tuner and the scanner. We even swapped os and still same thing. One thing we found odd is there was no counter for key off that is generated in the scanner when you change it....is that normal? Any help much appreciated.
