Description

The JB4 Tuner is a sophisticated, plug-and-play performance module designed for a range of BMW vehicles equipped with N63, N63R, and N63TU engines. It acts as an intermediary between your car's sensors and the DME/ECU, intelligently manipulating performance parameters to deliver significant speed and power enhancements without requiring an ECU flash or unlocking your ECU. This makes it a reliable and fully reversible tuning solution. Experience a substantial increase in performance with power gains of up to 100hp and 140tq to the wheels on a stock vehicle, leading to improved 0-60 and quarter-mile times. The JB4 Tuner comes equipped with multiple tuning maps suitable for various fuel types, including E85 ethanol blends, and features user-adjustable fuel control and boost-by-gear settings for optimized traction. Additional capabilities include reading and deleting fault codes, logging up to 40 engine parameters, and controlling exhaust flap operations on applicable models. The unit is housed in a durable billet aluminum enclosure and is designed and assembled in the USA, backed by a 5-year warranty. Integration is seamless with the included JB4 PRO adapter, which enables wireless connection to your smartphone via Bluetooth 4.0 for iOS and Android devices. The free JB4PRO app provides comprehensive data logging, performance map changes, firmware updates, and advanced log analysis tools to estimate performance and diagnose tuning concerns. Installation is quick and plug-and-play, though routing the ECU cable may require patience depending on the vehicle model. The JB4 is compatible with a wide array of BMW models including 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). Specific fitment varies by model year and chassis designation (e.g., F Chassis N63 TYPE_A/B, N63TU; G Chassis N63R). It is recommended to verify sensor fitment for certain 2012-2013 models. For vehicles not explicitly listed, contacting sales@burgertuning.com is advised.
