Yes,I have key-on and 12v on my bench harness,though they run to a common feed.I used Winflash to change the VIN as well as attempting to change VIN manually (in tuner,HxD,TP) and nothing has worked. Everything was done using full flash as well.
I read it out using Efi to confirm and still not changed.
Not sure what's up,doublechecked and i'm updated on winflash and TCII.
I'm using an optima to power the bench harness,plenty of voltage and fully charged.
I'm going to try just programming a completely different .cal and see what happens.
