Description
The Burger Tuning JB4 Gen3B is a true plug & play tuner for select VW, Audi, Skoda, and Seat 2.0T engines, delivering up to 30 horsepower and 45 lb-ft of torque to the wheels on a completely stock setup.
Installation takes minutes by connecting to easy-access engine bay sensors—no ECU flash required and fully compatible with locked ECUs. The JB4’s advanced 64mhz processor samples sensor data 800 times per second with 10-bit digital-to-analog converters, ensuring lightning-fast adjustments for optimal performance and reduced turbo lag.
With full CANbus OBDII integration, the JB4 reads critical engine data like throttle position, gear, AFR, fuel trims, ignition timing, and knock detection, adapting power delivery in real time for both performance and safety. It can even limit boost until oil and coolant reach optimal temperatures and reduce boost if overheating or detonation is detected.
Maps can be changed on the fly via the BMS data cable or JB4 Mobile Bluetooth app, letting you switch between stock, valet, and performance modes instantly.
