The AEM Flex Fuel Ethanol Content Sensor Kit (30-2201) provides precision monitoring of fuel ethanol percentage and temperature. Designed for use with programmable standalone engine management systems, this kit allows tuners to optimize engine calibrations in real-time based on the actual fuel blend. Since pump E85 can vary significantly from the labeled 85% ethanol, this sensor is a critical component for maintaining consistent performance and engine safety on flex-fuel builds.

This kit simplifies plumbing into existing fuel systems by including high-quality -6AN adapter fittings. The sensor outputs a frequency-based signal that communicates both ethanol concentration and fuel temperature to the ECU, enabling dynamic adjustments to ignition timing and fuel delivery. This is a vehicle-neutral kit compatible with most aftermarket engine management systems.

• Accurately measures ethanol content and fuel temperature in real-time
• Includes -6AN adapter fittings for easy fuel line integration
• Includes electrical connector, terminals, and wire seals for a secure harness
• Compatible with most aftermarket standalone ECUs capable of flex-fuel tuning
• Essential for protecting engines running variable ethanol blends
• Manufacturer Part Number: 30-2201

Optimize your engine's tune for varying ethanol blends with the AEM Flex Fuel Ethanol Content Sensor Kit. This essential component allows programmable engine management systems to precisely measure the fuel's ethanol percentage and temperature in real-time. Since "E85" fuel can vary significantly from the stated 85% ethanol content, this sensor provides accurate data, enabling your ECU to adjust tuning calibrations for consistent performance and engine safety.

• Measures fuel ethanol content percentage and fuel temperature.
• Enables dynamic ECU tuning calibration based on actual ethanol blend.
