Description
Running too lean while enjoying spirited driving in your vehicle is one of the leading causes of expensive engine damage. AutoMeter’s Narrowband Air/Fuel Gauges pair with older Oxygen Sensors to warn of lean burn conditions under heavy engine load. Connects directly to the factory O2 sensor on many applications, or uses the AutoMeter 2244 Narrowband O2 sensor. Not compatible with 5 wire air/fuel sensors.
ADDITIONAL NOTES

Feature Points

  • Compatible with factory narrowband O2 sensors (0-1V)
  • May require model 2244 if the vehicle does not have a factory narrowband primary O2 sensor
  • Features LED radial bar graph display (gauge does not have provision for backlight)
  • Will not work with wideband O2 sensors (0-5V) - please check your specific application before purchase

Questions

 I’m looking for the right wiring harness for 2010 genesis coupe 2 L turbo to work with NARROWBAND AIR/FUEL RATIO, LEAN-RICH, ULTRA-LITE #4375

Asked by: Mr.Mark
Hi Mark, thank you so much for contacting us. While I'm unaware of anyone making a model specific harness for the 2010 Genesis, on turbo models you can tee onto the the yellow wire at pin 38 of the ECU to get a signal. With that said, you will be much better served on your vehicle integrating a wideband air/fuel gauge. While the narrowband can serve as a warning for lean conditions under WOT, they aren't very useful as a tuning tool or to observe AFRs under all driving conditions. All of our widebands include both the wideband sender and harness. Here's a selection to check out: https://www.autometer.com/catalogsearch/result/?q=wideband+ratio+gauge#1&profile=products Hope this helps!

What are the afr readings at each light example would 14.7 be the 10th light reading from left to right

Asked by: Clif
Hi Clif, thank you so much for the question. Due to the limitations of a narrowband sensor, there's no way to pinpoint a specific LED to a specific A/F, nor would the gauge ever stay at a specific point. The last page of the instructions here will explain how it works in more detail: https://www.autometer.com/media/manual/2650-1163.pdf For a specific, actual A/F reading, you'd have to go with a Wideband gauge like this model 4379: https://www.autometer.com/2-1-16-wideband-a-f-street-ultra-lite.html

would this work on my car honda prelude 97 with h22a engine ? lol

Asked by: Kiko
Hi there, thanks for the question! Yes, your '97 Prelude should still have a narrowband O2 sensor which is what's required to run this Air/Fuel Ratio.

Hi is it possible to use this meter as a stand-alone unit.  Possibly connect it to an o2 sensor and insert it into the exhaust for reading. 

Asked by: Hayden
Hi Hayden, thank you so much for contacting us. Technically, you could us it in that way, but it's not really something we'd recommend. A Narrowband type Air/Fuel gauge such as this is really more of a warning for lean conditions under heavy throttle applications. It was designed to piggyback onto the existing narrowband O2Sensor in vehicles that were equipped with them from the factory. To see actual air/fuel readings for tuning, we'd very strongly recommend going with something like this unit: http://www.autometer.com/2-1-16-wideband-a-f-street-ultra-lite.html This will work perfectly with any pump gas applications and includes the sender, wiring harness and O2 bung all in the kit. Hope this helps!
