Progressive Controller

[ProStreetNova]

Anyone use a Nitrous Progressive Controller of some brand ?

If you do, do you run the nitrous safety solenoid?

For the life of me I can't figure out how that would work. I understand it would be the first nitrous solenoid that would be pulsating, but since the second solenoid is wired to the same 12 volt wire, wouldn't the second solenoid be pulsating too.

I know very little about NOS and even less about progressive controller's, but I do know a little about wiring.
If both of your solenoids are on the same circuit, but they do opposite "things" (like a safety system would be) then one is probably N/O and one is N/C.

My understanding is that one soleniod would be Normally Open, and the other Normally closed. The diagram I saw was that the nitrous line from the bottle goes to the redundant nitrous safety solenoid, then the nitrous runs from that safety soleniod to the second nitrous soleniod, then to the plate.

However what goofs me up is that the 12 volts goes to the first soleniod (lets say the Red wire), then the second soleniods Red wire is also wired to the same 12 volt wire. So how can the first one pulsate and not the second one. I think the controller controls the Ground for Activation.

Looks like I will have to call Mike (Nos) Nelson

the controller has 2 seperate wires for those solenoids. one wire (for the safety solenoid)is constant(ground that is) when activated and then the other comes and goes(grounds and ungrounds) through the time delay cycle. i choose not to run the safety solenoid in my application but if you do run it, be sure that it is the same part number as your primary solenoid. iow, make sure it is not smaller or you will lose out on your flow quality.

I was leaning towards not running one. Think I'll get some teflon seats and put those in my solenoids, have some for back-up too.
