I know that straight gas is generally expected to produce peak power with an air-fuel ratio in the range of 12.8 - 13.2. What about the typical 10% ethanol blend that everything local to me sells year around now? With the addition of a wideband O2 setup once The MoPig is back on the street, I'd like to have a general idea of what's "normal" for e10 pump gas. Thanks!
