This proprietary USB cable connects the JB3 G3 control box to your laptop, for use with 2.0s new 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. JB3 must be equipped with a G3 box. Please do not attempt to use a standard RS232/USB cable with the JB3 as it will not work and may damage the processor.
To use this cable you must first have the 2.0 firmware loaded on your G3 control box which you can burn using a chip burner. G3 upgrade boxes below will have the 2.0 firmware preloaded for you. Once the 2.0 firmware has been burned you will use this cable for all future updates.
