Air Fuel Ratio Sensor Module The PLX Air Fuel Ratio Sensor Module accurately measures the precise air fuel ratio (AFR) of any internal combustion engine. Up to 32 Sensor Modules can be daisy chained together from the PLX iMFD line for modular tuning. This Sensor Module can also be used as a stand alone unit capable of interfacing with third party hardware through the analog outputs. The SM-AFR works with gasoline, biodiesel, ethanol, methanol, E85, LPG, and CNG. Advanced soft start technology prolongs the O2 sensor life.
