Watch out, the piecewise linear approach he uses will NOT get you the
claimed accuracy of +-0.1AFR. Depending on what he's set the slopes on
each side of stoich, you will have an area in the curves somewhere on
either side where the errors are considerable. Ask me how I know. :)

You can prove this for yourself; get ahold of the NTK curves (they're in
incoming somewhere) and try to draw a couple straight lines thru them on
either side of stoich. Then look at the errors. Considerably more than
0.1AFR.

Just a word to the wise.
