JB4 Performance Tuner

The Burger Motorsports JB4 is a plug-and-play performance tuner engineered to optimize the performance of turbocharged Cadillac engines. It discreetly connects to easy-to-access sensors in the engine bay, working with your factory ECU to adjust boost, timing, and fueling for maximum performance gains and a significant reduction in turbo lag. Unlike flash remaps, the JB4 leaves no trace of its installation, ensuring your vehicle remains unaware of the enhanced performance levels and maintaining compatibility with all factory driving modes. Featuring advanced CANbus integration, the JB4 monitors critical engine parameters such as pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, and knock feedback in real-time. This capability allows for sophisticated tuning adjustments that go beyond basic piggyback systems, ensuring both enhanced performance and safety. The tuner comes preloaded with multiple maps supporting various fuel types including 91 and 93 octane, E85 mixtures, and unleaded race fuel, alongside a stock mode and VALET mode. Additional features of the JB4 include boost-by-gear control for improved launches and traction, the ability to read and delete fault codes, and extensive customization options. It also offers control over exhaust flap operation on supported vehicles. For enhanced functionality, the JB4 is compatible with the free JB4PRO smartphone app via Bluetooth 4.0, enabling wireless connection to iOS and Android devices for data analysis, map changes, and firmware updates. The JB4 is designed and assembled in the USA and includes a 5-year warranty. Optional harness extensions and a Boost Control Module (BCM) for specific CT4-V Blackwing models are also available.
