A method and system for operating a pump driven by an engine are disclosed, including adjusting and measuring a speed of the engine with a controller electrically coupled to the engine, the controller having encoded therein a computer-readable method of controlling a pump; receiving a first discharge pressure at a first engine speed from a discharge pressure sensor coupled to a discharge line of the pump, and a second discharge pressure at a second engine speed from the discharge pressure sensor; determining a pump constant and an intake pressure in response to the first and second engine speeds; determining a maximum engine speed in response to the pump constant, the intake pressure, and a desired discharge pressure; and, limiting the engine speed to the maximum engine speed.
