KyRaceFan said:good question, dont really know the answer, but that narrowband o2 wont really tell you much of anything when it comes to reading your a/f ratios other than a general idea.
Save up and get a real wideband, like an AEM UEGO or Tech Edge, or any other one if you really want to keep tabs on your a/f.
