Wolf, that is true about the narrow band if you are using the customary electronics, but if you are looking at a voltmeter, you can see just how lean or how rich it is. I am glad I didn't know anything beforehand. That is such a beautiful thing discovering things that others pass by because of things they read. I too read about these sensors and agree with your findings. But if you research further, you will find that the sensor is a manufacturer of voltage. It makes its own and reports depending on how rich or how lean the fuel mixture is. A max of 1 volt, a min of 0, and any number in between. It is not smart enough to skip over certain voltages, or flip flop or anything. Its just a sensor. Sensor connected direct to the voltmeter. I want a wide band now since I am using it for testing!
