duty cycle of solenoid valves?
(OP)
Looking at using a NO 3 way valve to shut off the boost signal to a waste gate. Porsche uses one on their 944 turbo to vary the boost as the EEM tells it. Do these valves operate off of straight 12VDC or a pulsed 12V & if so what frequency & duty cycle?

I think I am going to use no pulse, just DC to .9 of my boost, then a pulse, ? freq?, with a 50% duty cycle to start cracking waste gate , then off at my boost setting.
