Show original supplier description
The Burger Motorsports JB4 is a true user-adjustable, plug-and-play tuning solution for various MQB-based VW and Audi Group models. This device installs between your car's sensors and its ECU, manipulating performance parameters to increase speed and responsiveness. Initial power gains start at 35bhp and 40 ft-lb with 91 octane fuel, adding approximately 4.50psi of boost over stock. With bolt-on modifications, higher octane fuel, and adjustments via the optional wireless JB4PRO Bluetooth connection, gains can reach up to 90bhp and 70 ft-lb. The JB4 features advanced CANbus connectivity for comprehensive tuning. It includes direct AFR control, sophisticated safety systems for boost, air/fuel ratio, fuel trims, and engine knock detection. Additionally, it offers boost mapping by gear for enhanced traction and integrated water/meth control. The unit can be seamlessly integrated with the JB4PRO smartphone app (iOS/Android) for real-time engine parameter display, map switching, and firmware updates. The enclosure is constructed from billet aluminum and the unit is designed and assembled in the USA, backed by a 5-year warranty. Compatible vehicles include: Volkswagen: 2014-2021 VW MK7 Golf 1.8T US model, 2014-2021 VW MK7 Golf Alltrack, 2014-2021 VW MK7 Golf Sportwagen. Audi: 2014-2021 Audi A3 1.8T US Model.
