A variable lift valve is very similar to a pump speed system, low speed=low pressure=low flow=low atomisation.

The aquamist FAV is a (fixed lift) valve responding relatively linearly between 25-50HZ PWM drive signal.
Aquamist PWM FAV (fixed lift, constant line pressure):
Full pressure (good atomisation) at wide range PWM%. It requires a relatively simple control driver. All fuel injectors use this type of valve.

That you very much Richard for the time you took to explain. I understand it now very well. I also saw a thread from the Mitsubishi forum where you explained the systems in detail.
