Bluetooth your JB4 to your Phone Wirelessly!


IThe JB4 Connect Kit (Rev 3.7) allows your Bluetooth 4.0 compatible iOS and Android devices to connect wirelessly to your JB4. View critical engine data in real time, datalog, read codes, change maps, update settings, update firmware, and more, all from the palm of your hand! The REV3 mounts next to the JB4 in the engine bay eliminating the need to run a BMS DATA cable inside the cabin. It's compatible with all JB4 products. Just plug it in to the JB4 where your BMS DATA cable connects, attach the power and ground wire to the JB4 harness using the included connectors, purchase the JB4 Mobile app, and you're off and running. Please note the JB4 Mobile app is available for iPhone®, iOS, or Android® and sold separately via the Apple® or Android® app store on your phone. This adapter is not compatible with the JB4 windows interface.

Please Note: For use with older JB4 tuners with the square case.
