1. A control unit for overriding an ethanol sensor in a vehicle, the control unit comprising:

  • a housing between 0.1 liters and 2 liters in volume;

    one or more signal bearing wires for logically communicating a digital signal to a fuel control module of a vehicle, the wires configured to bypass an ethanol fuel sensor sensing ethanol passing through a fuel line of the vehicle;

    a button affixed to outside of the housing;

    an electronic signal relay module, housed within the housing, for relaying a digital signal to the fuel control module via the signal bearing medium used by the ethanol sensor, the digital signal overriding the ethanol sensor in response to the button on the housing being depressed, wherein the digital signal falsely indicates to the fuel control module that ethanol is being run through the fuel line.
