JB4 Performance Tuner

The Burger Motorsports JB4 is a plug-and-play performance tuner specifically engineered for turbocharged vehicles, including the 2016+ Infiniti Q50 and Q60 with the VR30 3.0L Twin Turbo V6 engine. This sophisticated system installs between your car's sensors and its ECU, manipulating performance parameters to deliver significant speed increases. Unlike flash tunes that can leave a permanent trace, the JB4 is designed to be discrete, making the vehicle unaware of the increased power output, and it can be fully removed without detection. Featuring a 64Mhz processor and full CANbus integration, the JB4 tuner accesses critical engine data directly from the ECU, including pedal position, throttle position, timing advance, fuel trims, air/fuel ratio, engine knock, and more. This real-time data allows for unparalleled tuning precision and smooth power delivery. The JB4 offers multiple maps tailored for different fuel types like 91 octane, 93 octane, E85 mixtures, and unleaded race gas, along with boost-by-gear settings for improved launches. It also provides the ability to read and delete fault codes. This particular configuration includes the JB4 PRO adapter, enabling seamless wireless connectivity to your iOS or Android device via Bluetooth 4.0. The companion free app allows for data analysis, map changes, and firmware updates. The adapter is designed to fit entirely within the JB4 enclosure for a clean and protected installation. The JB4 is CARB approved under Executive Order (EO) No.D-744-6 for specified 2016+ Infiniti Q50/Q60 3.0L Turbo models (Luxe, Sport, Silver Sport, Red Sport).
