I am suddenly having an issue where any ls1 ecu i try to write to pops up with "unlicensed vehicle"
It will read fine, just won't write.
Apparently this means the vehicle isn't supported but it is just your average old LS1 commodore (Australian) which I've been tuning with my MPVI2 for a while now.

I read somewhere that you could try deleting your License.dat file but the issue with that is it then looses all my MPVI1 licenses which i cant resync back as it was handed in when i upgraded to the MPVI2.

I have logged a support ticket but with 4 cars to tune in 1.5 days I need a solution that gets me going!
