JB4 Engine Tuning System

The Burger Motorsports JB4 Tuner is a sophisticated engine tuning system engineered for BMW vehicles equipped with N63, N63R, and N63TU engines. It delivers substantial performance enhancements, claiming up to 100 horsepower and 140 lb-ft of torque at the wheels on stock configurations. This tuner acts as an intermediary between your car's sensors and its DME/ECU, manipulating data to achieve improved performance. Key features of the JB4 Tuner include CANbus OBDII integration for advanced tuning capabilities, comprehensive data logging with the ability to view and record up to 40 real-time engine parameters via the JB4 app, and multiple preloaded performance maps tailored for various fuel grades and modification levels. It also supports boost-by-gear settings in 1st, 2nd, and 3rd gears for optimized launches, and is compatible with water-methanol injection (WMI) systems. The tuner offers seamless integration with JB4 Mobile for wireless data logging and tuning adjustments using Bluetooth 4.0 compatible iOS and Android devices, or via a BMS data cable for Windows laptops. For peak performance gains, the use of 91 octane fuel or higher is recommended. The JB4 Tuner runs as smoothly as stock during normal driving, ensuring drivability and maintaining fuel economy. It is not VIN locked and can be removed without leaving a trace, allowing for resale. The tuner comes housed in a rugged billet aluminum enclosure for durability and includes a 5-year warranty. It is proudly made in the USA. The JB4 Tuner is compatible with a wide range of BMW models, including various iterations of the 5 Series (F10, F11, F07, G30), 6 Series (F12, F13, F06), 7 Series (F01, F02, G12), 8 Series (G15, G14, G16), and X Series (E70, E71, F15, F16, G05, G06, G07) vehicles equipped with the N63 engine family. Specific harness selection may be required based on the chassis and engine variant (e.g., G Chassis N63R, F Chassis N63TU, F Chassis N63 TYPE_B, F Chassis N63 TYPE_A). Users are advised to verify sensor fitment for 2012-2013 F chassis models.
