JB4 BMS DATA Cable

BMS Data Cable for JB4

For those who don't want to use our Bluetooth adapter/free app we offer the BMS data cable. This allows an old school hardwire connection from your JB4 to a windows laptop for use with our free windows JB4 software. The BMS data cable and windows software provide the same functionality as the newer app including changing maps, loading firmware, and recording JB4 data logs, but does not include tuning insights or performance metrics.

Note: The BMS data cable is not compatible with MAC laptops. MAC owners should use our JB4PRO Bluetooth adapter via the free JB4PRO app for laptops!
