Burger Motorsport JB4 Performance Tune – BMW N20 / N26
The N20 / N26 JB4 expands upon the popular N20 / N26 Stage1 tune with CANbus functionality. This allows for multiple maps which can be changed in dash, built in diagnostics including code reading/deleting, ethanol support, and much more to come with free software updates.
Remember the JB4 does not require any additional modifications or previous stages. Simply install the JB4 as your first and only modification and enjoy an entirely new fast and smooth racing experience. The JB4 also does not require any user setup or customization but we strongly suggest the BMS DATA cable so you can load free software updates.
