So it’s much more linear than we thought. No math needed? The real test is compare it to a known good tailpipe sniffer. Westech?

We had the correct math the whole time. It’s all done for you on the scaling table.
(2.3750 * Volts) + 7.3125
If you do 2.3750 x .5 + 7.3125 you get your 8.50 on the first line. Just needed to figure out where in the dash to put the scale in.

I don’t think we’re allowed to play in the Westech sandbox anymore.
