Universal Air / Fuel Ratio Gauge by Auto Meter®. Monitoring your engine’s air/fuel ratio (AFR) is crucial if you want the best performance and want to avoid damage that could be caused by a lean condition. The Auto Meter Air/Fuel Ratio Gauge accurately displays AFR and is available in both wideband and narrowband versions. The wideband AFR gauge includes a 0-4V output for data acquisition or fuel management/ECU systems, so it’s ideal for tuning to make the most power without harming your engine. The narrowband gauge displays AFR on a 20 segment LED bar graph with red, yellow, and green segments that indicate lean, stoichiometric, and rich. Wideband gauges include 0.1 AFR resolution Bosch LSU 4.2 sensor for optimal accuracy, as well as wiring, stainless steel sensor mounting bung, and instructions. Narrowband gauges include wiring and work with most factory narrowband O2 sensors.

      Air and fuel must enter your engine’s cylinders in the correct ratio for optimal combustion, to make the most power. A mixture with too much fuel (a lower number on the gauge) is “rich”, which while safe for the engine, usually doesn’t enable it to make the most power. A mixture with too much air (a higher number on the gauge) is “lean”. A leaner mixture usually makes more power, but a mixture that is too lean can cause detonation and expensive engine damage. To know your engine’s AFR, you need an Auto Meter Air/Fuel Ratio Gauge, available for both factory narrowband O2 sensors and wideband sensors. The narrowband sensor displays AFR on a 20 segment LED bar graph with red, yellow, and green segments that indicate lean, stoichiometric, and rich. Because of the nature of narrowband O2 sensor operation, will bounce back and forth rapidly when at the stoichiometric AFR.

      The wideband Auto Meter Air/Fuel Ratio Gauge will accurately display the AFR in real time, so you can tune your engine to make the most power safely, and it includes a 0-4V output so you can use the AFR data with data acquisition and engine management/ECU systems. For optimal accuracy, a 0.1 AFR resolution Bosch LSU 4.2 wideband sensor is used. This sensor has an integrated calibration chip, which eliminates the need for free air calibration.

      The wideband AFR gauge can be used with both EFI and carbureted engines, and it’s available in 3 versions: an analog gauge with an 8:1-18:1 AFR range display, a Street version with 10:1-17:1 AFR digital and LED radial display with 16 radial bar graph segments, and a Pro version with programmable AFR digital and LED radial display with 30 radial bar graph segments. Gauge brightness can be manually adjusted on the analog and Street gauges; the Pro gauge includes a photo cell for automatic brightness control. The Street and Pro digital gauges have an LED radial bar graph at the perimeter of the gauge with amber, red, and green LEDs. These illuminate amber when the AFR is in the rich range, red when the AFR is in the lean range, and green when the AFR is in the optimal, stoichiometric range.

      In addition to the above, the Pro gauge can also display either AFR or Lambda values, and has WOT leanest mixture recall, programmable lean condition alarm, and adjustable stoichiometric point for use with alternative fuel types like ethanol, methanol, propane, and CNG (Compressed Natural Gas).

      Each gauge is available in popular Auto Meter gauge styles so you can match your other Auto Meter gauges, in 2 1/16” and 2 5/8” gauge housings. All wideband gauges include sensor, wiring, stainless steel sensor mounting bung, and comprehensive, illustrated instructions. The Air/Fuel Ratio Gauge is backed by a limited 1-year warranty against defects in materials and workmanship.
