AEM Flex Fuel E85 Content SensorAEMâs Flex Fuel Ethanol Content Sensor Kits measure a vehicleâs fuel ethanol content percentage and fuel temperature which allows users with programmable engine management systems (capable of tuning for flex fuel) the ability to optimize an engineâs tuning calibration for fuel ethanol content. While many gas stations label flex fuel as E85 (85% Ethanol and 15% Gasoline) actual ethanol content can be much different. Using AEMâs Flex Fuel Ethanol Content Sensor delivers the ability to determine the amount of fuel blend being used at any given time..This sensor is ideal for use with AEMâs Infinity standalone programmable ECU & Series 2 EMS on flex-fuel equipped vehicles or it can be connected to a dash display or data logger.AEM offers two Fuel Ethanol Content (Flex Fuel) Sensor Kits one with 3/8â barbed adapter fittings and one with -6AN to 3/8â adapter fittings (PN 30-2200 barbed fittings PN 30-2201 -6AN fittings).FitmentKit contentsFlex Fuel sensorTwo grooved fittings 3/8 "(also available with fittings Dash 6)Electrical connector and seal
