PLX Devices SM AFR Gauge Control Units

SM-AFR accurately measures the precise air/fuel ratio (AFR) of any internal combustion engine. Up to 32 SM-AFR modules can be daisy chained together in the iMFD system. SM-AFR can also be used as a stand alone unit capable of interfacing with 3rd party hardware. All Sensor Modules are housed in high quality extruded aluminum designed to operate even in the most extreme conditions. In addition, all SM modules offer outstanding digital accuracy, response and resolution which far exceeds that of a standard gauge.

    SM-AFR utilizes the latest digital PID and DSP technologies to maximize o2 sensor reaction time and accuracy without compromising overshoot, and slow settling response time. This technology is coupled with advanced self sensor calibration circuitry and sensor soft start to both prolong the life of your oxygen sensor as well as eliminating any user intervention for manual sensor calibration. PLX widebands may be used and installed in your vehicle permanently.

  • Wideband 0-5V analog linear output
  • Narrowband 0-1V analog output Replace your stock narrowband sensor

1006/13/2007Great product, highly recomended
1001/23/2007Unit performs flawlessly. Instuctions could be a little better. Overall best bang for the buck AFR device for a stock or aftermarket (I have it feeding both)engine management computers or data aquisition devices!
