Does anyone on here have experience with direct port nitrous systems? I have a single fogger wet zex kit right now and I love the throttle activated nitrous, but I want a direct port system b/c the nitrous is more evenly distributed with it so theres less chance of running lean. I know zex makes this TPS switch, would this work with a direct port kit?

Im pretty sure it will, just want to see if anyone here knows for sure. Im looking into the NX direct port kit btw.

WOT switches work with any application. All they do is tell the nitroud module to spray when the switch is activated and the nitrous system is armed.

It's called a TPS switch, but it looks like it's just an on/off switch that you can set the "on" point to depending on throttle angle. Not variable like the TPS itself. If this is the case, why not save yourself $80 and tap into the WOT switch built into the car? I assume all 240s have a WOT switch.

Where would the WOT switch be located if there is one?

Our cars dont have WOT switches AFAIK. The TPS is our only means of throttle measurement stock.
