JB4 Engine Tuner

The Burger Motorsports JB4 is a plug-and-play engine tuner designed for Kia, Hyundai, and Genesis vehicles with specific turbo engines. It works with your factory ECU to remap boost, timing, and fueling for optimal performance and reduced turbo lag. The JB4 features programmable CANbus, upgradable firmware, and data logging capabilities, allowing it to monitor various engine parameters for performance mapping and safety.

This tuner offers enhanced functionality and safety features, including boost pressure control based on oil and water temperature, and a low boost map for overheating or knocking conditions. It comes with preloaded maps for different fuel octanes and E85 mixtures, and fuel economy remains unchanged during normal driving. Installation is discrete and removable without a trace.
