The replaceable 2580 master chip controls the communications between the JB4 and your BMS data cable or JB4 Smart Phone Wireless Connect Kit as well as the model specific firmware. If unable to connect to the JB4 try replacing this first as often it's the culprit. Be sure to specify which firmware you need in the drop down for the chip to work properly with your model. We also have 2431 and 24K22 port injection integration and anti-lag firmware update chips in the drop down.
