JB4 2.5T SmartStream Plug-and-Play Tuner

The Burger Motorsports JB4 is a plug-and-play tuner designed for Kia, Hyundai, and Genesis 2.5T SmartStream engines. It works with your factory ECU to remap boost, timing, and fueling for optimal performance and reduced turbo lag. The JB4 features a 64MHz processor and samples sensors 800 times per second with 10-bit converters for smooth, powerful performance.

Unlike other tuning systems, the JB4 includes a programmable CANbus system, upgradable firmware, and data logging. It takes into account various sensor inputs to optimize performance mapping and includes safety features like low boost until engine warm-up and reduced boost under overheat or knock conditions. Installation is discrete and removable without a trace, and it includes maps for 91 octane, 93 octane, and E85 mixtures.
