For you mods you don't need to set the Alcohol PE any different than the Gasoline PE. You don't need to touch any density multipliers. But you do need to use the correct stoich values, populate the Ethanol Spark stuff, enable the Flex Diag and sensor stuff, and address the Torque Model for Ethanol. Early Gen V ECU's used different Torque Models for E. I'd rather have the car behave the same on 93 pump and on E.
