{"product_id":"jb4-b58-tuner-2","title":"JB4 B58 Tuner","description":"The Burger Motorsports JB4 B58 tuner is an advanced, plug-and-play tuning system engineered for GEN1 and GEN2 BMW B58 turbocharged engines. It delivers substantial performance enhancements, with the potential for up to 120 horsepower and 120 lb-ft of torque at the wheels on a stock engine running on pump gas. For those utilizing bolt-on upgrades, higher octane fuel, E85 mixtures, or larger turbochargers, even greater gains are achievable.\n\nInstallation is straightforward due to the JB4's plug-and-play wiring harness, allowing for quick setup and removal without permanent modification. The system offers sophisticated tuning features such as on-the-fly map switching between stock and performance maps, boost-by-gear control for optimized traction, and the ability to read and clear fault codes. It integrates seamlessly with the factory ECU, ensuring factory safety systems are maintained while improving turbo response, power delivery, and acceleration.\n\nThe JB4 tuner is compatible with the free JB4PRO smartphone app, which enables wireless connection to iOS and Android devices for real-time data analysis, map changes, and firmware updates. The app provides an intuitive interface for logging and analyzing vehicle data.\n\nThis JB4 tuner is compatible with GEN1 and GEN2 B58 engines. For the B58TU2 GEN3 motor, a different product is required. The JB4_B58 is CARB approved under Executive Order D-744-4 for numerous 2016-2018 BMW applications.
