OLED Touchscreen Display, shows the health of your o2 sensor, shows voltage, show reaction time to sensor, etc.  The gauge itself can also be hooked up to other modules so you can use it for more than just a wideband.  No more guessing if your sensor is going bad or working properly.

This is a 52mm or 2 1/16" gauge that is very thin with a hideaway module that you can mount anywhere like in  your dash.

We sell all the these items separately in other listings, so occasionally a customer will be mad thinking they got an open box item, but it is indeed brand new.  We just separate the items when they come in for inventory and we hologram sticker the AFR box so people don't try to swap parts.  We've in the past had people buy our unit and try to return an old bad one, so we have to take these measures to prevent scammers.  Also people see the picture and expect 3 boxes.  It is just two boxes.  The long large one in the picture is a paper cardboard sleeve that just goes over the two boxes.

Gen 4 Wideband AFR Gauge & Sensor Combo from PLX Devices

The new Generation 4 Wideband Sensor Controller is here!

We're proud to introduce our next generation wideband oxygen sensor controller with intelligent health monitoring technology and current for improved sensor performance. Our new Gen4 Wideband AFR Gauge Combo utilizes the next generation in Bosch Wideband Air/Fuel Ratio sensor technology. The Gen4 is faster, more accurate, more durable, and uses less power than the Gen3. The Gen4 also employs the innovative PLX Devices new intelligent health monitoring technology where the oxygen sensor is meticulously monitored every 2mS (488 times per second) to obtain peak performance, accuracy and reaction time. Coupled with the updated patented DM-6 touch screen MultiGauge, battery voltage is displayed from 9V-20V, sensor life is displayed from 0-100%. The oxygen sensor reaction time is displayed from 10mS/1000mS on the brilliant high contrast OLED display.

The PLX Wideband AFR (UEGO) gauge combo combines an accurate, fast response wideband AFR (Air Fuel Ratio) controller with the world's most advanced touch screen 2 1/16" gauge (52mm). It includes a Bosch LSU4.9 wideband oxygen sensor. The wideband controller (SM-AFR) works with gasoline, bio diesel, ethanol, methanol, E85, LPG, and CNG. It includes two analog outputs (wideband 0-5V, and narrowband 0-1V) for interfacing with 3rd party devices and one digital serial output for interfacing with the DM-6 gauge and other Multi Gauges. The wideband analog output is ideal for interfacing with aftermarket ECU's and data loggers. The narrowband output is ideal for stock narrowband oxygen sensor replacement where the simulated narrowband analog output is fed back into your ECU to make it operate as if the stock narrowband oxygen sensor is still installed while running the PLX wideband setup. All three outputs can be used simultaneously. Additional features include advanced soft start technology which prolongs the oxygen sensor's life and an aluminum enclosure for durability and reliability.
