I just finished installing my NX nitrous kit and I wanted to take it for a spin and try it out, when my digital MSD window switch started acting up. It would just go down to 0 when I was accelerating and driving but at idle it would show the rpm fine.

Any help is appreciated.

Just took it out for another spin and it seems fine if i rev it in neutral up to about 2-3000 rpm. It shows the rpms fine but once i start driving it just goes down to zero. Also when i arm my system (no nitrous in the bottle yet) and i go WOT at my set window (4000 - 6500 rpm) it bogs down for a second, so it is spraying fuel for sec.

I am thinking that my signal that I am getting from my coil negative cable is not strong enough. But I am wondering about why I would get a perfect signal when i am idling, and nothing when I am driving. Does the signal get weaker the higher u rev?
