Attached is a copy of the design I came up with for A/F meter.  Oxygen
sensor curve as well as voltage/LED assignments.  Note that the lower 10
LEDs and Upper 10 LEDS are spread over the regions of the curve of most
interest for tuning. While LED #10 covers the approx 0.4 volt region around
t he center of the curve which is not of much interest in tuning.
