Power gains of up to 60hp and 80tq to the wheels with a stock vehicle, up to 100hp to the wheels with the Blackwing!
This plug and play tuner attaches to easy to access sensors in the engine bay and works with your factory ECU tuning to remap your boost, timing, and fueling for optimal performance and reduced turbo lag.
Installation is very discrete and unlike flash remaps which are quick to install but can never be fully removed with a JB4 the vehicle is never aware it's making more than the factory boost or power levels. Fuel economy during normal driving is unchanged and it's compatible with all driving modes including towing.
Unlike other less advanced systems, the JB4 includes CANbus functionality allowing it to take in critical engine data directly from the ECU for real-time tuning. The data includes pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, fuel trims, gear, and much more. Other tuners without CANbus are not able to even monitor this critical engine data no less incorporate it real-time into their tuning algorithms. CANbus allows the JB4 to provide huge power increases with unparalleled power delivery.
The JB4 includes multiple maps including those for 91 octane, 93 octane, factory tuning, VALET mode, E85 mixtures, and unleaded race gas. In addition, it offers boost by gear settings to improve launches, the ability to read and delete fault codes, and much more. The JB4 is made in the USA and includes a 5-year warranty.
Wirelessly Connect to your JB4: Add the all-new JB4 PRO smartphone connection to wirelessly connect the JB4 tuner to your Bluetooth-compatible iOS or Android device. Record and analyze vehicle data, change maps on the fly, and update firmware as we release free updates with new features and more powerful tuning maps. The adapter fits inside the JB4 enclosure for enhanced weather protection and a cleaner installation. The JB4PRO free app offers an intuitive interface, help features, and advanced log analysis tools to estimate performance and identify tuning issues.

What is a JB4?
The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and the DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.
Is the JB4 a real tune?
Yes. By tapping into engine sensors and CANbus data in real time, the JB4 can adjust boost, timing, AFR, and fuel trims similar to an ECU reflash, while retaining factory safety systems and avoiding ECU unlocking or flash flags.
