NTK UEGO calibration

[Bruce]

I've gotten erratic readings using Butane, used it with a NB O2 numerous
times, and no ignition.
Anyone with a TIG Welder would probaby be using a sheilding gas, and be able
to *fill* a bottle enough to double check the O2's calibration, I'd imagine.

If your watching it's output side to side, with a NB, you should be able to
get a rough idea of what 14.7 is like.  Remembering that the oem stuff
toggles across Stoi..
