Method and system for controlling a two stroke engine based on fuel pressure

A system comprising:

• an engine;
• a fuel system comprising a fuel pressure sensor, fuel temperature sensor and a fuel injector;
• a controller in communication with the fuel pressure sensor, fuel temperature sensor and controlling the fuel injector with a fuel pulsewidth determined by determining a beginning time of a window for measuring fuel pressure, wherein the beginning time is a function of electrical injection, mechanical injection, fuel acceleration time, and sensor delay, determining an ending time of the window, measuring fuel pressure between the beginning time and the ending time, determining a fuel pulsewidth based on the fuel pressure and fuel temperature and injecting fuel into the engine in response to a desired fuel mass.
