Rich, to be clear, the M3W does not have a standard OBDII port, so standard OBD tools won't work here.
As Chris and Richard have noted above, you will need the Protune software loaded on a computer and connected with a USB cable with a mini B male end for the ECU, as shown in the link below. These should be readily available on Amazon.
