Performance Tuner Module

The Burger N20-JB4 is a high-performance tuning module specifically designed for BMW N20 and N26 2.0L Turbo 4 Cylinder engines. This plug-and-play device installs between your car's sensors and its DME/ECU to manipulate vehicle performance, delivering substantial power increases. Ready to take your BMW N20 turbo to the next level, the JB4 can provide up to 50hp to the wheels (65hp crank) on a completely stock car, or up to 100hp to the wheels (120hp crank) on a fully modified car. The JB4 tuner operates by tapping into specific sensors and CANbus for real-time vehicle data, allowing it to alter boost, timing, and fuel trims safely and smoothly, comparable to an ECU reflash but without permanently altering the DME. It is not VIN-locked, meaning it can be easily moved to another vehicle or resold. Key features include multiple tuning maps for different fuel types, boost-by-gear control for improved traction, built-in diagnostic code reading and deleting, an in-dash boost gauge display, and exhaust flapper control. The unit also supports E85 ethanol blends and offers better performance and safety than basic chip tunes. For enhanced functionality, it is compatible with the free JB4PRO smartphone app (iOS/Android) for data logging, performance analysis, map changes, and firmware updates via Bluetooth. The JB4 includes a billet aluminum enclosure and comes with a 5-year warranty. It requires 91 octane or better for optimal performance gains and has no impact on fuel economy during normal driving.
