Ethanol Content Sensor

This sensor measures the percentage of ethanol present in your fuel lines in real-time, allowing your ECU to adjust fueling and ignition timing automatically for Flex Fuel setups.

Yes, in addition to ethanol percentage, this digital sensor also reads fuel temperature. This data helps the ECU optimize cold starts and density corrections.

For most high-performance applications, we recommend installing the sensor on the fuel return line. This ensures accurate readings without creating a potential flow restriction in the feed line.

Yes, this flow-through sensor is the industry standard for Flex Fuel integration and works seamlessly with major ECU brands like MoTeC, Syvecs, Haltech, and Emtron.

The flow-through design is efficient for most setups. However, for extremely high-horsepower fuel systems, we suggest using a bypass or parallel plumbing strategy to ensure zero restriction.
