JB4 Performance Tuner Module

The Burger Motorsports JB4 Tuner is a sophisticated, plug-and-play performance module engineered to enhance the power and torque output of the Toyota GR Corolla. It integrates seamlessly with your vehicle's factory DME tuning by attaching to two easily accessible engine bay sensors, allowing it to remap boost, timing, and fueling parameters for optimal performance and a noticeable reduction in turbo lag. The JB4 features a high-speed processor and digital-to-analog converters that sample sensors 800 times per second, ensuring smooth and potent power delivery. This tuner offers significant performance gains, with up to 30 wheel horsepower and 40 wheel torque on a stock vehicle, and can improve 0-60 and quarter-mile times. It comes preloaded with custom tuning software for the Toyota GR Yaris/GR Corolla, featuring up to eight maps for various fuel levels and modifications, including compatibility with ethanol (E85) blends. The JB4 also provides advanced functionality such as reading and deleting fault codes, and displaying/recording up to 40 engine parameters in real-time via the JB4 app. Boost by gear control for the first three gears can be managed through the app for optimized launches. Fuel economy remains unchanged during normal driving, and it is compatible with all driving modes. A minimum of 91 octane fuel is required to achieve performance gains. The unit includes a rugged billet aluminum enclosure for durability and is made in the USA. For enhanced functionality, the JB4 is compatible with JB4 Mobile for smartphone logging and tuning adjustments, and requires a separate JB4 Mobile app purchase.
