JB4 Performance Tuner

The Burger Motorsports JB4 Performance Tuner is a plug-and-play device designed to enhance the performance of turbocharged Infiniti vehicles. It installs by connecting to two easily accessible sensors in the engine bay, working in conjunction with your factory DME tuning to remap boost, timing, and fueling parameters. This sophisticated system utilizes a 64MHz processor, sampling sensors 800 times per second to ensure smooth and responsive power delivery. The JB4 offers a significant performance upgrade, with power gains of up to 40hp and 40tq to the wheels on a stock vehicle, and also improves 0-60 and quarter-mile times. This tuner comes equipped with the JB4PRO adapter and free app, allowing for wireless connection to your iOS or Android device via Bluetooth 4.0. Through the app, you can record and analyze vehicle and tuning data, switch between performance maps, and update the JB4 firmware as new versions become available. The app features an intuitive interface with help buttons and advanced log analysis tools to help you understand your car's performance and identify any tuning concerns. The JB4PRO adapter is integrated into the JB4 enclosure for enhanced weather protection and a cleaner look. Installation is quick and simple, taking under a minute, and the unit can be just as easily removed without a trace when necessary. Fuel economy during normal driving remains unchanged. The JB4 offers multiple tuning maps suitable for different fuel types, including support for E85 ethanol blends, and can read and delete fault codes. It also provides features like boost by gear control for improved traction and controls exhaust flap operation on supported vehicles. The JB4 is compatible with all driving modes and offers a better performance and safety profile than basic chip tunes. It requires 91 octane or better for optimal performance gains and is not VIN locked, allowing for easy removal and resale. This JB4 tuner is specifically designed for the 2016+ Infiniti Q50 2.0L Turbo Pure, 2016-2022 Infiniti Q60 2.0L Turbo Pure, and 2016-2019 Infiniti QX30 2.0L Turbo models. It includes a billet aluminum enclosure, is designed and assembled in the USA, and comes with a 5-year warranty.
