This is not our software, we didn't create it. We're just giving you a place to find it. If you cant figure out the install or something isn't working, there are other versions floating around the web you can try. JB4 Mobile is a mobile data logger and display for use with the JB4 tuner from Burger Motorsports. JB4 Mobile allows you to monitor multiple parameters of your JB4 equipped car at once.

Laptop connection using our BMS Data Cable via free Windows and Mac software. (conventional serial cables will not work and possibly damage the board). Via Bluetooth using our JB4 Connect kit that is IOS and Android compatible. The Bluetooth device replaces the need for our BMS Data Cable.
