B58 X5 X7 Flex Fuel Kit

The Burger Motorsports G05 B58 X5 Flex Fuel Kit is essential for owners of B58-powered BMW X5 and X7 vehicles running E85 fuel. It eliminates the guesswork associated with varying ethanol content at the pump, which can range from E50 to E85 or higher depending on the season and station. This kit provides real-time ethanol content monitoring directly through the Fuel-It! or JB4 mobile applications via Bluetooth. The kit utilizes ethanol-safe PTFE fuel lines and fittings, and it integrates via a plug-and-play fuel line connection. Installation is designed to be simple, taking approximately 30 minutes without requiring any cutting or permanent modifications to the vehicle. Beyond real-time monitoring, the kit offers a 0-5V analog output, allowing for seamless integration with JB4 or other flash tuning solutions. This enables users to optimize engine timing and boost levels safely when running ethanol blends. The system also comes with free firmware updates and free Bluetooth app control, offering continuous improvement and easy access to data. With this flex fuel sensor, you can confidently dial in your exact E85 blend at every fill-up. This helps prevent running too much ethanol on a pump gas map, maximizes performance potential on ethanol maps, and ensures consistent power delivery at the track. Ultimately, it protects your engine by providing critical data about your fuel mixture. Vehicle fitment includes the 2019-2026 G05 B58 BMW X5 40i (including sDrive40i and xDrive40i) and the 2019+ G07 B58 BMW X7 xDrive40i. For integration with the BMW G Chassis JB4 platform, the white wire should be connected to position #4 on the JB4 25-pin harness, and the WMI Ethanol Setup option 0 must be selected to enable the flex fuel input on pin locations 2/3/4.
