Show original supplier description
The Fuel-It! FLEX FUEL KIT is a comprehensive solution for integrating a Bluetooth-enabled flex fuel analyzer and ethanol sensor into your vehicle's fuel system. This universal kit allows you to monitor your E85 fuel mixture in real-time, providing valuable data for performance tuning and engine management. The analyzer features multiple output options to suit various setups: a linear 0-5V analog output (where 0 volts equals 0% ethanol and increases proportionally) and a 50-150Hz raw signal output directly from the ethanol sensor (where 50Hz equals 0% ethanol and increases linearly). All analyzer options include the Fuel-It! Universal Bluetooth analyzer, a genuine Continental ethanol sensor, electrical connections for power and ground. Optional fittings are available in anodized billet aluminum, including push-lock barbed connections for use with socketless fuel hoses (5/16" or 3/8") and quick-connect fittings compatible with many stock fuel lines (typically 3/8" for domestic and 5/16" for European manufacturers). Please verify your vehicle's fuel line size before ordering. Fuel lines are sold separately, and hose clamps may also be required. To utilize the Bluetooth functionality, a separate third-party app for your Android or Apple smartphone must be downloaded. Links to these apps are provided on the product page.
