Press Release Summary = We\'ve had a few reports where users could not "nail down"
their tune on the street with the LM-1. The AFR\'s would jump about 0.5 AFR across
the WOT band even in the same weather conditions in the space of a few days. Instead
of holding a tune, the engine seemed to slowly "yodel."

Press Release Body = We\'ve had a few reports where users could not "nail down" their
tune on the street with the LM-1. The AFR\'s would jump about 0.5 AFR across the WOT
band even in the same weather conditions in the space of a few days. Instead of
holding a tune, the engine seemed to slowly "yodel."

Naturally the first thing to blame was the LM-1. But it turned out that the users
filled up at different gas stations, sometimes filling up on gas that had 10%
ethanol mixed in. As expected, when Schnapps is mixed with cars, things get a little
complicated.

If ethanol (stoich AFR of 9) is mixed with gasoline (stoich AFR of 14.7) the
resulting gas has a lower stoich AFR than \'pure\' gasoline. As the fuel injection is
tuned to mix a certain amount of fuel for a given amount of air, the resulting
mixture would be leaner when using a fuel with lower stoich AFR.

This can be calculated:
