Review on Optimized Auto Meter 4375 Ultra-Lite Electric Air Fuel Ratio Gauge by Eric Pavelko
Not very useful sensor
Autometer makes very good quality sensors. This sensor is no exception when it comes to build quality, but unfortunately the narrow-band AFR (air-fuel ratio) sensor isn't very useful. It connects to the car's standard oxygen sensor, and as a result you'll see a constant back and forth movement from full rich to full lean on the sensor. You get a nice light show but no useful information. Luckily, Autometer will be releasing a wideband AFR sensor soon, which will include a Bosch wideband oxygen sensor. This setting provides useful information. Until then, skip this narrowband setup and save money for something useful.
