Air Fuel Ratio Sensor Module

 

plxwidebandThe PLX Air Fuel Ratio Sensor Module accurately measures the precise wideband air fuel ratio (AFR) of any internal combustion engine. Up to 32 Sensor Modules can be daisy chained together in the PLX iMFD system. This Sensor Module can also be used as a stand alone unit capable of interfacing with 3rd party hardware. Works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. The PLX requires no free air calibration nor a heat sink on the sensor element. It’s 0-5V output can be used with all data systems. $209 with Bosch LSU 4.2 sensor.
