Description
If you’re running E85 or ethanol blends in your BMW, the Fuel-It! Bluetooth Ethanol Content Analyzer Kit is an essential upgrade. This complete plug-and-play solution allows you to monitor your exact ethanol content in real time using your smartphone or JB4-compatible tuning platform.
Designed specifically for BMW F-Series vehicles, this kit replaces the factory fuel lines from the fuel tank to the engine bay with upgraded -6AN E85-compatible fuel lines. It also integrates a high-quality ethanol sensor and Bluetooth analyzer, providing accurate flex fuel data for safer tuning and maximum performance.
The system supports both Bluetooth app monitoring and a 5V analog output, making it ideal for JB4 users or flash tuning setups. All kits utilize custom billet aluminum fittings that integrate directly with factory connections, ensuring a clean installation with no permanent modifications required.
