0000181: Provide advanced injector dead time characterisation
Post the initial opening period of an injection cycle, the flow of the injector is non linear with time. This is likely to do with a variety of factors including inertia of the the fuel and rebound of the pintle etc.

More info on the symptoms, but not the causes, here:

Need to think carefully about just how to do this for maximum intuitiveness, maximum accuracy and minimum memory usage.
No tags attached.
