The JB4 is an easy-to-install plug and play tuner that attaches to sensors in the engine bay and works with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag. Includes full SENT sensor technology required for properly tuning the latest Audi platforms.
Full CANbus integration allows the JB4 to access and incorporate engine data in its tuning strategies and enables unique safety features—such as limiting boost until oil and coolant temperatures are optimal, and switching to a low-boost map if the engine overheats, runs lean, knocks excessively, or overboosts. Includes fuel control for ethanol mixture mapping.
Fully compatible with JB4 Mobile for map changes, data logging, firmware updates, and more. Installation is discreet and the unit can be removed without a trace. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in the USA. 5-year warranty.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS or Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow recording and analysis of vehicle data, performance map changes, and firmware updates. (JB4 Mobile app required.)
