Question on one tune for different vehicles

[tcope12]

Need some insight on this situation:

Have an Autocal married to Car A
Have another Autocal married to Car B

(both are the same type of vehicle)

Have sperate aftermarket tunes for each vehicle on each Autocal

For Car A I _also_ have a tune which is a slightly modified aftermarket tune. It is not in use.

I copy the modified tune from Autocal A to AutoCal B and it installs on Car B

So the modified tune I have for Car A can be used on the other vehicle? Perhaps only when it's not currently installed? Is this normal or if the modified tune not locked down by the creator for some reason?

I'm just trying to understand how this would normally work and how it applies to my situation. Hope I explained that correctly.

The license is tied to the ECM/PCM processor serial number so if both Vehicles are using the same operating system its possible.
