But I think the injector (and stepper) Digi WUR had analogue pressure sensors too?
The other point is while an appropriate pressure sensor may be able to smooth the pulses out as far as any readout goes, if they still actually exist in the system, they are going to show up at the airplate, which in turn is going to set up a pulsing motion in the CP line.
The best option by far is to find a fuel delivery system that can eliminate the pulsing (IMHO).
You have probably worked it out by now, from memory the UT system was actually using the injector to bleed fuel off to waste (return) rather than injecting fuel in to control CP. (If that helps as a design option).
