Fuel injection map and closed loop lambda feedback

I have now managed to successfully map my engine simulator for the fuel injection timings across all loads and engine speeds. I have set up a two dimensional array, of speed and throttle position, and inside each element is the time in microseconds (us) that the fuel injector should be open for. I’ve also added closed loop lambda feedback.

Ignition Timing, Engine and Fuel Map

I have now implemented more accurate ignition timing control which is based on degrees before top dead centre rather than a fixed time period.

I’ve also implemented a simple fuel map with the ability to store new values, display the map and save the map over serial from the Arduino.
