1. A method of mapping and modeling an engine during an engine development process, comprising: testing said engine over a plurality of actual engine operating conditions; gathering actual engine data corresponding to said actual engine operating conditions; determining a plurality of parameter functions based on said actual engine data, each of said plurality of parameter functions corresponding to an engine operating parameter; providing an engine simulation model based on said plurality of actual engine operating conditions and said plurality of virtual engine operating conditions; and generating a plurality of engine maps using said engine simulation model.
