I love Autometer gauges. They are high quality. Mine stayed in the warm up mode. It also froze at 14.2 when it worked. I would turn the ignition off and restart the car. Then it would work correctly. I sent Autometer some emails describing my problem. Ultimately it was decided to replace the gauge.

Given Auto Meter's supposedly good reputation, I thought that this time I would try an Auto Meter 3370 Sport-Comp Wide Band Air Fuel Ratio Kit. Turns out to be not very good at all.Instead of a smooth transition of output voltage, it steps and that makes data acquisition look like stair steps.It also appears to be way off in output accuracy and displayed values compared to two brand new OEM O2 sensors. I understand that the range of OEM O2 sensors is limited but the Auto Meter gauge display and output does not track the OEM O2 sensors.Just to be sure, I tried an AEM gauge and sensor and that worked so much better than the Auto Meter. And zero help from Auto Meter. So I've wasted over $200 on Auto Meter but will never make that mistake again.
