JB4 + PRO BT Adapter Performance Tuner

The Burger Motorsports Alfa Romeo JB4 + PRO BT Adapter is an advanced plug-and-play performance tuning system for turbocharged Alfa Romeo vehicles. This tuner operates by interfacing with the car's sensors and ECU, allowing it to modify boost pressure, ignition timing, and fuel delivery to significantly enhance performance. It utilizes CANbus integration for sophisticated data communication and offers features typically found in more complex tuning solutions. The included PRO BT Adapter enables wireless connectivity to a smartphone via Bluetooth 4.0, allowing users to monitor vehicle data, switch between performance maps on the fly, and update the tuner's firmware with free updates from BMS. The accompanying JB4PRO app provides an intuitive interface for logging, analysis, and even estimating performance metrics. Key benefits include power gains of up to 40hp to the wheels on stock vehicles, with potential for greater increases when combined with other aftermarket parts. It supports multiple tuning maps for various fuel types and E85 blends, improves 0-60 and quarter-mile times, and offers features such as boost-by-gear control for better traction, built-in data logging for up to 40 engine parameters, and the ability to read and delete fault codes. This JB4 tuner is specifically designed for the 2017+ Alfa Romeo Giulia 2.0L 4-cylinder Turbo and the 2017+ Alfa Romeo Stelvio 2.0L 4-cylinder Turbo. It requires a minimum of 91 octane fuel for optimal performance gains and is not VIN-locked, allowing for easy removal and resale. The JB4 system is built into a billet aluminum enclosure and is assembled in the USA, backed by a 5-year warranty.
