Can anyone out there help???? I have a nitrous kit fitted to my Astra (oznos kit) with 50bhp jets for now. Before increasing jets size I would like to fit Nitrous controller manufactured by NOS. To see if the controller is compatable. I need to determine the AMP draw from my fuel and nitrous solenoids. Does anyone know how I can work this out? Tried putting volt meter on battery took a reading then switched solenoids on individually, got a crazy reading. Less than 1amp, can't be right!

What brand and line of solenoids do you have?

check the settings on your voltmeter.
The nitrous controller is a pretty andvanced peice for such a simple system. why spend so much?
the controller is mainly used for 2 stage systems and the like by pro racers. It will probably not be worth it for a simple system like yours.
