JB4 + PRO BT Adapter Tuning System

The BURGERMOTORSPORTS Alfa Romeo JB4 + PRO BT Adapter is an advanced tuning system engineered for 2017 and newer Alfa Romeo Giulia and Stelvio models equipped with the 2.0L 4-cylinder turbo engine. This plug-and-play tuner installs between your vehicle's sensors and the DME/ECU, manipulating performance parameters to deliver significant speed improvements. This system boasts power gains of up to 40hp to the wheels (55hp crank) on a stock vehicle using pump gas, with even higher gains possible with aftermarket parts, higher octane fuel, or larger turbos. It features a simple plug-and-play harness for easy installation and removal, and is not VIN-locked. The JB4 includes features such as on-the-fly map switching via your smartphone, boost limiting by gear for improved traction, built-in data logging, and fault code reading and deletion. Included with this tuner is the JB4 PRO smartphone connection, which allows wireless connection to a Bluetooth 4.0 compatible iOS or Android device. The accompanying free app provides an intuitive interface for analyzing vehicle and tuning data, changing performance maps, and updating firmware. The adapter integrates fully within the JB4 enclosure for a cleaner look and enhanced weather protection. Key benefits and features include multiple tuning maps for different fuel types, E85 ethanol blend support, boost-by-gear control, exhaust flap operation control on supported vehicles, full CANbus integration, and smooth stock-like operation. It requires 91 octane or better for optimal performance gains and comes with a 5-year warranty. The enclosure is constructed from billet aluminum and the system is designed and assembled in the USA.
