"Trinity Demo Crom"

[Nathan195]

Getting a message that says the original backup must be restored to that vehicle before tuning another vehicle is possible and when I hit more information it says last vehicle vin: diablo sport demo. Also it shows trinity not married yet. can't get it to do anything on my truck

options/change vehicle type, select demo, let it reboot
go to performance, select original backup, let it do its thing.
then options/change vehicle type and select your vehicle then you may tune it.

Thanks
