Optional BMS Data Cable:
This proprietary Data cable connects the JB control box to your laptop for use with Burger Motorsports datalogging, tuning, and map loading software. Cable may be left in engine bay and routed in the window or door when needed for a simple install. Alternatively it may also be routed behind the ECU in to the glove box for a clean install and on the fly access.
Please do not attempt to use a standard RS232/USB cable with the JB as it will not work and may damage the processor. All JB software is posted on n54tech.com.
