Ok guys I'm a newb in nitrous and don’t know if I need to get the WOT switch if I had MSD digital widow switch?

In fact I don’t know what is the purpose of the WOT if I already got a window switch!!

Could you please answer me if I have to get a WOT switch?


BTW, its a street A4 car and im gonna use the TNT F2 kit.

Thanks in advance.

 

Assuming your car is the Car in your sig and not a drive by wire car this will explain it.

The windowswitch simply tells the system at what rpm to activate and disactivate for safety.

A wot switch is a machanical switch that is placed at the butterfly of the throttle body. This switch breaks the circut to the system. Once you go wide open throttle the butterfly clicks the switch completing the circut. Its telling the car you are at wide open throttle and its ok to spray..

Here is what they look like.

Some windowswitches have what is called a Thottle position sensor built in. (TPS) This works by reading the voltage of the TPS sensor and then completing the circut when it sees you are at wide open throttle. This does away with the machanical wot switch. The MSD does not offer this feature. So you either need a wot switch with bracket or a TPS switch.
