I am looking to add a dry shot of NO2 to my car andcompensate fuel with MS. I am using the deal card. My main question is do I provide the MS trigger (master arm switch ) a 12v or ground signal? In addition can the deal out driver trigger the solenoid directly or do I need to use a relay?

Second question is the max rpm drop down in the tuner studio setting the same as a max rpm activation like a typical NO2 controller?

 

you need a relay and the signal from the ms goes to the - side of the relay.

 

Even through the deal card output?

 

If you want to drive the solenoid directly, you'll need to upgrade the drive transistor. Those solenoids pull a lot more than a relay. The small signal transistors on the Zeal card are good only for 300mA or something...

But, if you aren't using the idle output on the Zeal card, you can re-purpose to drive your NOS solenoid.

 

Good idea. I actually stopped using the PWM valve since its basically a drag car
