Description
Burger Motorsports BMW B58 GEN3 engine tuner device
The JB4 stands out as the premier tuning system tailored for B58 GEN3 powered vehicles, offering unparalleled sophistication and performance enhancements. With power gains of up to 100whp to the wheels (equivalent to 125hp at the crank) on a stock car running 93 octane fuel, and even greater increases with ethanol blends, it represents a significant leap in engine optimization.
Engineered specifically for the latest B58 variant, this new JB4 BMW tuner boasts the ability to process ultra-fast SENT digital sensor signals in real time, ensuring minimal latency. Its plug & play installation harness facilitates easy setup and removal, while its feature set sets it apart from competitors. These include in-app map switching between factory and performance settings, gear-based boost limiting for improved traction, progressive water/methanol support, built-in data logging, code reading capabilities, and more.
It’s worth noting that the JB4 requires no additional modifications or prior stages. Simply installing the JB4 transforms the driving experience, delivering newfound speed and smoothness. While user setup or customization isn’t mandatory, for those interested in logging data or accessing additional features, the Bluetooth mobile phone adapter is recommended.
Wirelessly connecting the JB4 BMW tuner to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop using the BMS data cable, enables you to record and analyze vehicle and tuning data, switch between JB4 performance maps, and update JB4 firmware as newer versions are released with updates, more powerful maps, and new features in development. Please note that a separate purchase of the JB4 Mobile app is required.
