JB4 + PRO BT Adapter

The Burger Alfa Romeo JB4 + PRO BT Adapter is a plug-and-play tuning system designed for turbocharged vehicles, enhancing performance by installing between the car's sensors and the ECU. This system manipulates vehicle performance through these connections, making the vehicle significantly faster. The JB4 distinguishes itself with advanced features like CANbus integration, fuel and spark control, and Bluetooth connectivity to your smartphone. BMS consistently releases free mapping and firmware updates, adding performance and new features as development progresses. This JB4 tuner offers power gains of up to 40hp to the wheels (55hp crank) on a completely stock car running on pump gas, with even higher gains possible when using bolt-on parts, higher octane fuel, and larger turbos. It features a simple plug-and-play harness for easy installation and removal, and includes features such as on-the-fly map switching via smartphone, boost limiting by gear for improved traction, progressive water/methanol support, built-in data logging, and fault code reading. The JB4 PRO smartphone connection allows for wireless connection to your JB4 tuner via Bluetooth 4.0 for iOS or Android devices, enabling recording and analysis of vehicle and tuning data, changing performance maps, and updating firmware. The JB4 is compatible with the free JB4PRO app and offers better performance and safety than basic chip tunes. It runs as smoothly as stock, is compatible with all driving modes, and has no impact on fuel economy during normal driving. It requires 91 octane or better for performance gains and is not VIN locked, making it fully removable. The system includes a billet aluminum enclosure and is designed and assembled in the USA, backed by a 5-year warranty.
