JB4 Performance Tuner

The Burger JB4 Performance Tuner (JB4PRO) is an advanced plug-and-play solution for the Kia Stinger and Genesis G70 3.3L turbo models, designed to enhance performance by optimizing boost, timing, and fueling. It integrates with the factory ECU, offering a significant reduction in turbo lag and an increase in overall power. The tuner utilizes a sophisticated CANbus system that monitors and adjusts parameters such as pedal input, throttle position, gear, engine speed, air/fuel ratio, fuel trims, ignition advance, and knock. This allows for dynamic performance mapping and ensures safety by maintaining low boost until the engine reaches optimal operating temperature and reducing boost if critical parameters like overheating, lean conditions, excessive knock, or overboost are detected. This tuner is compatible with various fuel types, including 91 octane, 93 octane, and E85 (ethanol fuel) mixtures, with fuel economy remaining unchanged during normal driving. The JB4PRO version further enhances functionality with built-in Bluetooth for smartphone connectivity via the free JB4 app, allowing users to change maps, log and analyze data, and update firmware. The app provides real-time parameter monitoring for up to 40 gauges and allows for boost-by-gear control in 1st, 2nd, and 3rd gears for optimal launches. The rugged billet aluminum enclosure ensures durability, and the product is designed and assembled in the USA with a 5-year warranty. Vehicle fitment includes the 2018-2023 Kia Stinger GT, GT1, GT2 (3.3L Turbo) and the 2018+ Genesis G70/G80 and 2017+ Genesis G90 (all 3.3L Turbo). For optimal performance with higher boost levels, it is recommended to upgrade spark plugs if they have over 25,000 miles.
