Performance Tuning Module

The Burger Motorsports N20 JB4 is a plug-and-play performance tuning module engineered to unlock the potential of your BMW's turbocharged N20 or N26 engine. Designed for immediate power gains, this module can deliver up to 50 wheel horsepower and 60 wheel torque on a stock vehicle, and up to 100 wheel horsepower on a fully modified car, significantly improving 0-60 and quarter-mile times. The JB4 is constructed with a billet aluminum enclosure and includes a user-friendly plug-and-play installation harness that requires no special tools and can be completed in minutes. Unlike flash tunes, the JB4 is not VIN-locked and can be easily removed or transferred to another vehicle. It offers advanced features such as multiple tuning maps for various fuel types (including E85 compatibility), built-in diagnostic code reading and deletion, boost-by-gear control for enhanced traction, and the ability to display and log up to 40 engine parameters. Furthermore, the JB4 integrates with the free JB4PRO app via Bluetooth, allowing for wireless connection to iOS and Android devices. This app enables real-time data analysis, performance map adjustments, and firmware updates. The module also controls exhaust flap operation on supported vehicles and runs as smoothly as stock, remaining compatible with all driving modes and having no impact on fuel economy during normal operation. It requires a minimum of 91 octane fuel for optimal performance gains. This tuning system is designed and assembled in the USA and comes with a 5-year warranty.
