The AutoMeter Z-Series 52mm electric air/fuel ratio gauge monitors narrowband O2 sensor signals to help detect lean conditions during spirited driving. It connects directly to factory narrowband sensors (0–1V) or to Autometer’s model 2244 narrowband O2 sensor when a factory narrowband primary sensor is absent. This gauge is not compatible with 5V wideband sensors; it uses an LED radial bar graph display and is built for applications that rely on conventional narrowband O2 feedback.
