Show original supplier description
The Burger Tuning JB4 is a plug and play performance tuner that attaches to easily accessible sensors in the engine bay. It works in conjunction with your factory ECU tuning to remap boost, timing, and fueling for optimal performance and reduced turbo lag, all without the risks and expenses associated with flash tuning. Installation is discrete, and the JB4 can be quickly removed without a trace. Fuel economy during normal driving remains unchanged, and it is compatible with all driving modes. The JB4 offers several performance maps that can be changed using the optional JB4 Mobile adapter and smartphone app. These maps are designed for various fuel types, including 91 octane, 93 octane, E85 mixtures, and a VALET/low boost mode. The tuner allows for wireless connection to a Bluetooth-compatible iOS or Android device for data logging, map changes, and firmware updates. It also offers features such as reading and deleting fault codes, boost-by-gear control, and CANbus integration. Made in the USA, the JB4 comes with a 5-year warranty. Power gains of up to 120hp and 120tq to the wheels are possible on a stock B58 engine with 91 octane or better fuel. For applications requiring higher power, vehicles equipped with bolt-on upgrades, higher octane fuel, E85 mixtures, or larger turbochargers can see even greater gains. The JB4 is not VIN locked and can be removed and resold.
