The ultimate tuner for your S55 powered vehicle, the JB4 allows you to go from factory stock to full race, and everywhere in between, with the push of a button on your steering wheel or phone. The JB4 installs and removes easily and includes many unique features not found in any other tune including user adjustable 1st and 2nd gear boost limiting, map switching in dash, electronic wastegate control, ethanol fuel support, and built in advanced CANbus based diagnostic tools. Installation is completely removable with no splicing or cutting of factory wires.

The JB4 is compatible with the factory flash map, competition package flash map, all off the shelf flash maps, custom tuned flash maps, or any flash map you choose to load! For those who don't mind flashing BMS provides free back end flash maps designed to optimize performance for specific builds and fuels saving you hundreds of dollars and many hours of time on custom flash tuning.

For the latest performance results, updates, firmware, and map guide be sure to visit N54tech.com.

For those running aftermarket turbocharged systems with aftermarket Tial wastegate(s) we have a special version of the S55 JB4 specifically to control them. Email us so we can manually invoice you for the JB4_S55_TIAL version.

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.
