The JB4 Wireless Bluetooth Connect Kit (Rev 3.7) allows your Bluetooth 4.0 compatible Apple® iOS® and Android® devices to connect wirelessly to your JB4 via the JB4 app. View critical engine data in real time, datalog, read codes, change maps, update settings, update firmware, and more, all wirelessly 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, purchase the JB4 Mobile app (see below), 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. The wireless adapter is not compatible with the JB4 windows interface. See our other listings for the "BMS DATA cable" for laptop use.
