Show original supplier description
The Burger Motorsports JB4 Tuner is an advanced performance tuning system engineered for various BMW models equipped with N63, N63R, and N63TU engines. It delivers significant power improvements, with claims of up to 100hp and 140tq gains at the wheels on stock vehicles, enhancing both 0-60 and 1/4 mile times. This tuner integrates seamlessly with your vehicle's systems, offering CANbus OBDII integration for advanced features and safety. It comes preloaded with custom JB4 BMW tuning software, featuring up to 8 maps tailored for different fuel levels and modification setups, including compatibility for Ethanol (E85) tuning. The system also allows for reading and deleting fault codes, and viewing/recording up to 40 real-time engine parameters through the JB4 app. The JB4 Tuner is compatible with JB4 Mobile for wireless connectivity via Bluetooth 4.0 to iOS and Android devices, enabling tuning changes, data analysis, and firmware updates. A separate JB4 Mobile app purchase is required. For Windows laptop users, a BMS data cable is also available for data logging and analysis. Additional features include user-adjustable fuel control, boost-by-gear settings for optimized launches in first, second, and third gears, and support for Water Methanol Injection (WMI). The JB4 Tuner runs as smoothly as stock during normal driving, with unchanged fuel economy, and requires 91 octane fuel or better for optimal performance gains. It is not VIN locked and can be removed without leaving a trace. The unit is housed in a rugged billet aluminum enclosure and is made in the USA, backed by a 5-year warranty.
