Water Meth Solenoid Setup

Hi all and thanks for helping me out

I have a water methanol kit from snow performance including a solenoid.

I want to run the whole system by my ECU and pmu. So the solenoid will be connected directly to a driven output of the ECU and directed by a pwm signal.

Question: which frequency should I use for the solenoid and which duty cycle to start?

Of course the dc depends on the boost I am running...

Thanks for giving advise

In my experience with the Snow solenoids, 30hz is a good place to start.
