Doh! I'm an idiot. :-)
I've been reading so many O2 sensor pages lately that I started
reading this one and I thought it was one that I had read previously
so I went on to other things. I didn't check out the discussion
on the bottom. Thanks for pointing that out!!
For anyone who's interested, it appears as though the air/fuel
ratio cannot be determined by a normal O2 sensor, as they are
non-linear and generally not accurate enough. Basically, they
can tell lean/rich only. (> 450mv is rich, < 450mv is lean).
There *are* O2 sensors which can be used to compute the actual
ratio, but they cost hundreds of dollars.
Oh well. :-(
(All that is stated at the very bottom, in the last post,
though there are great tidbits throughout the page.)
