Claim:
1. A method of testing the fuel efficiency of an internal combustion engine (ICE) having a fuel injector, comprising: sensing, via at least one sensor, at least one operational parameter of the ICE while the ICE is running, wherein the operational parameter has a first value, and wherein the fuel injector is configured to be controlled by changes in the operational parameter; controlling the fuel injector by substituting the first value with a second value when the first value reaches a predetermined value, wherein an injector spray valve of the fuel injector is maintained in an open position for a time sufficient to deliver an amount of fuel to the ICE based on the second value, and wherein the second value does not correspond to the operational parameter of the ICE while the ICE is running; measuring the fuel efficiency of the ICE after the controlling of the fuel injector; and further comprising monitoring the first value after the substituting of the first value with the second value, and controlling the fuel injector by removing the substituted second value when the first value falls outside of a predetermined range during the controlling of the fuel injector with the substituted second value.
