Well John since I can't adjust the timing on a race kart I have no choice
but to adjust A/F ratio. Since this works though and since the O2 sensor
doesn't do a great job under WOT conditions, I'm thinking this might be a
decent way to adjust A/F for maximum power under WOT conditions. Using EFI
on the street in a production type scenario is not necessarily what I have
in mind.  8)
