Learn news things everyday.
You have to be careful here. Ethanol is always going to be "richer" in the literal sense of air to fuel ratio than gasoline because its stoichiometric point is richer. However, it can require less "enrichment" (in terms of lambda) because it has a cooling effect and less tendency to knock.
