JB4 Tuner N55 Pneumatic Wastegate Type A Harness

The Burger Motorsports JB4 Tuner is a versatile and adaptable performance modification designed for a straightforward, plug-and-play installation on compatible BMW N55 engines. It supports vehicles with a pneumatic wastegate and Type A harness, including F06, F07, F10, F12, and F13 chassis models. This tuner allows for significant power and torque increases, with documented gains of up to 60 wheel horsepower and 60 lb-ft of torque on stock vehicles, and potential gains exceeding 100 WHP on modified setups. The JB4 offers advanced features such as multiple tuning maps for different fuel types, including E85 support, boost-by-gear control for enhanced traction, and the ability to read and delete fault codes. It can display and log up to 40 engine parameters, control exhaust flap operation, and integrates fully with the vehicle's CANbus system. Unlike basic chip tunes, the JB4 aims to provide superior performance and safety, running as smoothly as stock and being compatible with all driving modes without impacting fuel economy during normal operation. A 5-year warranty is included, and the unit features a billet aluminum enclosure. Designed and assembled in the USA, the JB4 is not VIN-locked and is fully removable. The JB4PRO app, accessible via an optional Bluetooth 4.0 connection, enables wireless datalogging, performance analysis, map changes, and firmware updates on compatible iOS and Android devices.
