When using an O2 sensor XGauge (from the XGauge examples PDF), the range is 0-99. How does one interpret the reading? What number would be stoich, which direction is lean/rich, and how far does it have to go before it's abnormally rich/lean?
I've tried the a/f xgauge, after a day or two I got bored with it. The number doesn't change much on my vehicle, maybe by .1 every once in a while. The O2 sensor reading will be 0 in DFCO. In most driving it will be in the 50's-60's. The highest I ever recall the reading being is 80 or 81.
