Air:Fuel ratios on narrow band oxygen sensors?

Those who really wanted to contribute to the search, contributed. Those who didn’t, didn’t. The ones who matter, to me, are the ones who did. Thanks.

Here is a wide band link. Really gets into the chemistry of combustion. I actually understand the math part. Unbelievable what a little book learning will do. http://www.megamanual.com/PWC/LSU4.htm

Actually, I’ve done a LOT of book learning…thousands of hours, probably, if not, tens of thousands of hours. On some searches, in available book form, or available electronic form, the information is just not there.
Thanks for the link.
