The Sensor Assembly - Flex Fuel (MPN 13507129) is a precision fuel system component designed for vehicles equipped with flex fuel capability. This sensor assembly monitors fuel composition in real time, allowing the engine management system to adjust ignition timing, fuel injection duration, and air-fuel ratio based on the ethanol content of the fuel blend. It is suitable for tuners, performance enthusiasts, and daily drivers looking to maximize efficiency and power across variable fuel qualities.
This assembly ensures optimal combustion efficiency and power delivery across all fuel grades, including E85, E10, and conventional gasoline. Utilizing capacitive technology, it detects ethanol percentage with high accuracy and rapid response time. The compact design measures 3.8 x 1.8 x 4.5 inches and weighs just 0.13 lbs, allowing for seamless integration into modern fuel system architectures.
The sensor communicates directly with the engine control module (ECM), providing critical data that enables closed-loop fuel compensation and prevents detonation when running aggressive ethanol blends. Its robust construction withstands fuel system pressures and chemical exposure, ensuring long-term reliability in demanding motorsports and street applications. This sensor assembly is particularly valuable for those exploring E85 performance tunes, which require precise ethanol content monitoring.
