Hello Brian,
Interesting idea. Have you talked to keith about your mixture reader?
He has a fairly fancy looking homemade one. Which type of O2 sensor are
you using?? I have heard that the 1 wire type are useless -that the two
wire type are better but really only give good readings around the ideal
mixture-their range is not broad enough. Have you heard about these 5-wire
sensors?? They are supposed to be able to give lots more info over a much
broader range than the other...problem is I believe that they are at least
twice as much as a two wire model.
