Burger Tuning JB4 Tuner - BMW N63R Engine - G Series

The JB4 is the most advanced and highly featured tuning system available for plug-n-play performance for your BMW N63R engine platform. The JB4 features a simple plug & play installation harness for easy installation & removal and includes many features not found with any other tune. Including on the fly in dash map switching between factory and various performance maps, optional in-dash gauge displays for boost, boost limiting by gear for improved traction in lower gears, progressive water/methanol support, built-in data logging, built-in code reading, optional direct EWG control to prevent throttle closure with exhaust modifications, exhaust flapper control, and much more.

Note for 2018+ G chassis vehicles with the digital dash layout Burger has not yet added in the JB4 commands to allow in-dash control but will provide those via a free firmware update once developed. Until then a JB4 mobile adapter or BMS data cable is required for any map and setting changes.
