When you say CANBUS port I assume you are not referring to the OBD2 port?
CANbus port is not the same as the OBD2 port, although you can access the CANbus via the OBD2 port. All cars are this way. Hyundai/Kia used to have a CANbus port under the hood, it is a different connector shape than OBD is.
Lap3 told me that since Hyundai has eliminated the CANbus port that they will likely come up with a solution to tie into the CANbus via the OBD2.
At this point I think I will just return the Pro Tuner and wait for the swappable ECU.
