Hi John, welcome again to the forum

AutoTap is not licensed to a vehicle.
EFILive V5 is not licensed to a vehicle.

There are several things:
- the AutoTap cable does not provide the ability to flash PCM's;
- the EFILive V5 software does not provide the ability to flash PCM's;

To flash late model [Gen5] Camaro you will need the EFILive FlashScan V2 interface (and software V7/V8).

I pm'd Tech Support for more guidance.

Cheers
Joe
