OBDII gets critical engine data like air/fuel ratio, timing, fuel trims, throttle position, pedal position, gear, oil temp, etc, etc, to the JB4. It's the reason the JB4 is able to provide a much stronger, smoother, and safer tune than any other system out there. The Bluetooth adapter on the other hand gets that same data from the JB4 to your mobile phone.
Without the OBDII attached the JB4 will revert to a map similar to the B58 JB+, fixed 4psi boost across the board.
