100% stroke at a fixed 0.2bar differential pressure is 100% fuel delivery
Percentages mentioned above refer to the unit capacity - so at maximum effective control piston stroke and a fixed pressure we would have 100% delivery for that unit- at least in theory
so the later ones with secondary or primary control of the differential pressure may effectively allow the max delivery of the unit to vary between say 80% and 120% at full travel

The lambda heads may in fact have the same top end delivery as the earlier ones if the FV is used to drop control pressure, or it could be the metering slits or the outlet port orifices are the limiting factor and altering differential pressure has little or no effect at max flow?
I don't recall seeing anyone with a setup that used the FV for control, I think it has always been CP based adjustment and sometimes using a Frequency Valve on the control pressure circuit.

Yes! mechanical/hydraulic constant flow injection can be managed by a modern EMS
