Description
The Burger Tuning JB4 is the most advanced plug-and-play performance tuner available for Kia, Hyundai, and Genesis turbocharged engines—delivering up to 100 horsepower and 100 lb-ft of torque to the wheels on a stock vehicle.
Unlike basic piggyback chips, the JB4 integrates directly with your factory ECU via CANbus, allowing it to read and adapt to real-time engine data including throttle position, gear, AFR, knock, ignition timing, fuel trims, and more. This ensures smooth power delivery, enhanced safety, and maximum performance without the risks of a full ECU flash.
Its 64mhz processor samples sensors 1000 times per second, providing razor-sharp tuning adjustments to optimize boost, timing, and fueling. Preloaded maps cover 91 & 93 octane, E85 blends, valet mode, and stock mode—switchable on the fly with a JB4 Mobile or BMS Data Cable. Installation is fully reversible with no ECU trace left behind.
