Description
Unlock the full potential of your Kia or Hyundai 1.6L turbocharged engine with the Burger Tuning BMS JB4 Performance Tuner V1. Designed and assembled in the USA, the JB4 is an advanced plug-and-play tuning system that works alongside your factory ECU to deliver substantial horsepower and torque gains while maintaining factory drivability and safety systems.
Capable of producing gains of up to 60whp and 60wtq on a stock vehicle, the JB4 improves acceleration, throttle response, turbo spool, and overall driving performance without permanently altering your factory ECU. Installation is fully reversible and discreet, making it ideal for enthusiasts who want serious performance without ECU flashing.
The JB4 system uses advanced CANbus integration to monitor and adjust key engine parameters in real time, including boost, ignition timing, fueling, air/fuel ratios, throttle position, gear selection, fuel trims, knock control, and more. This intelligent tuning strategy allows the JB4 to deliver smooth and reliable power while preserving OEM safety protocols.
The included JB4PRO adapter with built-in Bluetooth connectivity allows wireless control through the free JB4 mobile app for iOS and Android devices. Drivers can change tuning maps, monitor live engine data, log performance metrics, update firmware, and analyze vehicle performance directly from their smartphone.
The JB4 also includes advanced safety features that help protect the engine and turbocharger by reducing boost during unsafe operating conditions such as overheating, excessive knock, lean conditions, or improper oil and coolant temperatures.
Built for both stock and heavily modified vehicles, the JB4PRO system includes integrated ethanol sensor processing, onboard data logging memory, built-in CPI/WMI control, plug-and-play O2 bias wiring, and support for additional pressure sensors for expanded monitoring capabilities.

What Makes the JB4 Different?
Unlike basic performance chips or simple boost controllers, the JB4 is a true intelligent tuning system that actively communicates with your vehicle through CANbus integration. By processing live engine data in real time, the JB4 can safely optimize boost pressure, ignition timing, fueling, and air/fuel ratios for maximum performance and reliability.
The system retains factory ECU safety systems while providing power gains comparable to ECU flashes, all without permanently modifying or unlocking the factory ECU. Since the JB4 is not VIN-locked, it can be removed, transferred to another compatible vehicle, or resold later.
Burger Tuning has continuously developed and improved the JB4 platform for over a decade, making it one of the most trusted and widely used plug-and-play turbo tuning solutions available worldwide.
