The JB4 Tuner includes CANbus, full data logging, multiple performance maps, user-adjustable fuel control, boost by gear settings, WMI support, JB4 Mobile wireless compatibility, and much more. Compatible both as stand-alone tuning systems or in conjunction with performance flash maps where logging, safety, and fine-tuning tools are desirable.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. A separate JB4 Mobile app purchase is also required.
