Description
Take control of your fuel mixture with the CANFlex Flex Fuel Ethanol Content Sensor Kit, designed specifically for 2025+ Gen 3 B48-powered MINI models. If you're running E85, ethanol blends, or varying fuel mixtures, this complete flex fuel system provides accurate, real-time ethanol content monitoring through the CANFlex or JB4 app on your smartphone or tablet.
The CANFlex ECA combines an ethanol content analyzer, E85 analyzer, flex fuel sensor, Bluetooth monitor, and CANbus interface into one compact system. It uses a genuine Continental® ethanol sensor to measure the ethanol concentration in your fuel and communicates the data through CANbus, Bluetooth, the integrated LCD display, and a 5V output for legacy applications.
Designed for a straightforward installation, the complete kit can typically be installed in approximately 30 minutes. The included custom billet fittings, steel-braided fuel line, extension harness, and installation accessories provide the components needed for a clean and reliable installation.
For MINI owners using a JB4 tuning system, CANFlex provides seamless ethanol-content monitoring and real-time data integration. This allows you to monitor the actual ethanol content of your fuel and provides valuable information for ethanol-blend tuning and performance applications.
Whether you're running E85, mixed ethanol blends, or simply want accurate fuel composition data, the CANFlex Flex Fuel Ethanol Content Sensor provides a convenient way to monitor ethanol content in real time while keeping the information accessible through your smartphone, tablet, or built-in display.
