What cables are needed to go with the original sert black box by mastertune ? I have have the SEPST but I doubt thoughs cables would work with it.

 

The cable that connects from the SERT to the bike is the same.

The cable from the SERT to the computer is the one that is different. It connects to an old serial port. DB9.

If you only have usb ports on your computer you will need a usb to serial adapter also. The Belkin model F5U109 is the one I used.

I have the cable and belkin adapter I no longer need. Interested? I bought the new unit from Harley.
