All oxygen sensors put off the same voltage at different a/f ratios. If you can find the sensor curve some place, you hook your voltmeter to the sensor and voila, you have an A/F ratio monitor.

EDIT: You're shooting for .5 volts, higher is rich (up to 1 volt), lower is lean.

you will want 500mv at idle or cruise ONLY...at WOT you will want somewhere around 800-900. Remember...a narrow band O2 is not as accurate as a wide band O2...this will give you a ballpark setting for your fuel system. I have used a narroe band many times with good results....and a wide band gives you GREAT results..
