What would the Stoich AFR be for fuels blended with Ethanol like E10 90 Octane. how would i go about compensating for this?
E10 will give you a stoichiometric AFR of approximately 14.1:1. If you tune using lambda then it simply doesn't matter as lambda 1.00 is always stoich regardless of the fuel. In reality E10 blends can be treated in the same was as normal gasoline in most respects.
