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. Includes full CANbus allowing the JB4 to access and incorporate all engine data in its tuning strategies, incorporate unique safety features such as keeping boost pressure low until oil and water are up to temperature to provide proper engine and turbo lubrication, and drop to a low boost map if the engine starts to overheat, run lean, excessively knock, or over boost. Includes fuel control for ethanol mixture mapping. Fully compatible with JB4 mobile for on-the-fly map changes, data logging, firmware updates, and much more. Installation is very discrete and it quickly removes without a trace when needed. Fuel economy during normal driving is unchanged. Compatible with all driving modes. Made in the USA. 5-year warranty.

Wirelessly Connect to your JB4: Our all-new JB4 PRO smartphone connection is included to wirelessly connect the JB4 tuner to your Bluetooth 4.0 compatible iOS or Android device. This option allows you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Our new adapter fits fully inside the JB4 enclosure for enhanced weather protection and a more streamlined look. The JB4PRO Free app features an intuitive easy-to-use interface, help buttons, and advanced log analysis tools that can estimate the performance of your car and help identify any tuning concerns.
