when we are dealing with drops over fractions of a second, the time for the pressure sender to detect and open a valve is significant. if the only downside to having the valve open all the time is potential depletion of the pressurised oil supply, then using an accelerometer to open the valve in an anticipatory basis is a good compromise. OR, i presume you are using the 40 psi switch; what about the 55 psi switch that might catch dips a little sooner?
