Abstract
A method for operating a flex fuel conversion system for efficiently providing an aftermarket fuel delivery system which allows a vehicle to be operated on gasoline, ethanol or any combination of gasoline and ethanol. The a method for operating a flex fuel conversion system generally includes providing a fuel sensor to measure a current alcohol level of fuel within a fuel stream of an engine; providing a microprocessor, wherein a first signal including the current alcohol level of the fuel is sent to the microprocessor from the fuel sensor and the current alcohol level is subsequently compared to an optimal alcohol level; providing a fuel flow valve(s), wherein an adjustment signal is sent to the fuel flow valve(s) from the microprocessor, wherein the adjustment signal informs the fuel flow valve(s) how much additional fuel of the fuel stream to inject within the engine or how much fuel of the fuel stream to prevent from entering the engine in order to achieve the optimal alcohol level and then adjusting the amount of fuel injected within the engine via the fuel flow valve(s).
