JB4 Plug-and-Play Tuner

The Burger Motorsports JB4 Group 11 tuner is a plug-and-play performance enhancement for select Audi 4.0TFSI models. This tuner attaches to existing sensors in the engine bay and interfaces with your vehicle's factory ECU. It remaps boost pressure, ignition timing, and fueling parameters to optimize performance, reduce turbo lag, and provide significant power gains. The JB4 system offers advanced features, including full CANbus integration, which allows it to access and utilize all available engine data for its tuning strategies. This enables sophisticated safety protocols, such as maintaining low boost until the engine and oil reach optimal operating temperatures, and automatically reducing boost if the engine detects overheating, lean conditions, excessive knocking, or over-boosting. It also supports E85 ethanol blends and offers boost-by-gear control for improved traction. This tuner is fully compatible with the free JB4 PRO smartphone app, available for iOS and Android devices. The app allows for wireless connectivity, enabling on-the-fly map changes, real-time vehicle data logging and analysis, and free firmware updates. The JB4 is designed for a quick installation and is fully reversible, meaning it can be removed without a trace. It is backed by a 5-year warranty and is designed and assembled in the USA. Fitment includes: 2013-2018 Audi C7/C7.5 S6, 2013-2018 Audi C7/7.5 S7, 2014-2018 Audi S8, 2014-2018 Audi RS6, 2014-2018 Audi RS7, and 2014-2018 Audi A8 4.0TT models.
