Tuning more than one car

[saxmanvtx]

What happens to your backed up stock tune, when you go to program another vehicle? Does the backup to the new vehicle over write your previous backup. Or does the trinity keep them per vehicle or vin?

It won't work. Once theres a backup on the units, its locked until you restore the backup to the car.

Well that's a bummer. Have two trucks and was hoping to tune them both with one tool.

You can tune them both, but only one at a time. One always has to have the stock tune on it.
