Power gains of up to 80hp and 100tq to the wheels on a stock vehicle
Our latest tuning kit the F90 //M JB4 takes every thing that is great about the 2018+ all wheel drive F90 M5 platform and amps it up to the next level. Power gains of up to 80whp and 100wtq bring the car to life allowing 1/4 mile potential deep in to the 10s. Unlike other generic tuning devices the JB4 includes full CANbus integration via the OBDII port for advanced tuning, safety features, and diagnostics, as well as electronic wastegate control for superior boost targeting. This is simply the best tuning box available for your //M.

Installation is fully reversible attaching to the TMAP sensors and OBDII port. The included electronic wastegate (EWG) wires are optional and allow the JB4 to take direct control of the wastegates for more precise boost targeting for higher boost maps. Firmware update loaded via JB4 Mobile or a BMS Data Cable will be provided free of charge as we expand the JB4’s performance, maps, and features with future development.

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. Separate JB4 Mobile app purchase also required.
