Performance Tuner

The Burger Motorsports N63JB4 is a performance tuner engineered to significantly enhance the power and responsiveness of compatible BMW vehicles featuring the N63, N63R, or N63TU V8 engines. This advanced tuning system bypasses the need for ECU flashing, making it a safe and reversible option that doesn't VIN-lock to your vehicle. It is designed for quick plug-and-play installation, typically taking 20-30 minutes, and directly interfaces with your car's sensors and DME/ECU to optimize performance. This tuner offers substantial performance improvements, with claims of up to 100hp and 140tq gains at the wheels on a stock vehicle, leading to improved 0-60 and quarter-mile times. Key features include multiple tuning maps for various fuel types, support for E85 ethanol blends, fault code reading and deletion, display and logging of up to 40 engine parameters, and boost-by-gear control for enhanced traction. It also manages exhaust flap operation on applicable models and runs as smoothly as stock, without impacting fuel economy during normal driving. The JB4 requires a minimum of 91 octane fuel for optimal performance gains. The JB4's innovative design is further enhanced by the integrated JB4PRO adapter, enabling free Bluetooth app control via iOS and Android devices. This allows for wireless connection to analyze vehicle and tuning data, switch performance maps, and update firmware with free, ongoing releases. The accompanying JB4PRO app offers an intuitive interface with advanced log analysis tools. The tuner itself is built with a durable billet aluminum enclosure, is designed and assembled in the USA, and is backed by a 5-year warranty.
