Bought a ZEX Wet Kit from a guy at work for 300 Brand new. I'm a BB50trim with all supporting fuel mods running SCT Tune.
Will I need a MSD Tach??
Will I need a MSD Window Switch and a WOT Switch.
I have the N2MB WOT/2-Step does this help me at all??
How can I tap into my fuel system I'm running AGP Return line kit.
You only need the MSD tach driver if you are putting in certain window switches
You can use any window switch or no window switch at all. I would highly recommend one though.
You don't need an electrical WOT switch but it helps
Get a t fitting and put it off the return line for fuel
What would be some window switches that don't require a MSD tach if you know!
Something running off a DIS ignition box ???
To the OP:
The tach driver is a must if you are going to use a window switch. The window switch is far safer than running just a WOT switch and can be dialed in for the RPMs you desire. The WOT switch can be engaged right off of idle and that could be very destructive.
You can run both the window switch and WOT switch together.
For fuel, if you put in an adjustable fuel pressure regulator (not a boost/vac referenced one) in the line to the fuel solenoid, you can adjust the fuel enrichment very easily and be more precise than putting in a jet that's just "close" to what you need.
If the used kit didn't have all of the wiring with it, make sure you run the solenoids off of a relay!
My setup is simple....WOT switch and a hand held switch.With the small shots most of us run (50-75 hp) you don't need all the gizmo's.Hitting the rev limiter when power shifting isn't going to do shit but make noise.You can get a backfire if activated at to low of an rpm... to that i say just don't do it.I leave the line with the nitrous flowing and i can control it with the WOT switch.
The window switch allows the nitrous to turn on and off at a predetermined rpm....for example on at 3000 off at 6000 anywhere in between is it window of operation.You will need a tach driver to supply the window switch an rpm (tach) signal. A full throttle switch and of course some sort of arming switch is all you must have... the window switch makes the whole setup fool proof i guess.A bottle warmer and nitrous pressure gauge is nice also to keep the nitrous system consistent.

So this window switch Hooks up the the Tach To read where your at on RPMS then when it hits the RANGE then it allows the SOMETHING to turn on??How are people setting up Full throttle switches??? Sorry for these questions just trying to learn??
"WOT" switches are typically simple momentary switches that have an armature that engages the throttle cam or the underside of the gas pedal when it is floored, thus only completing the circuit when a desired throttle position is met.
Any redundant activation systems are excellent safety measures!
Engaging nitrous at low RPMS can turn your intake manifold into a combustion chamber. Look up "Nitrous Backfire" on youtube to see some good carnage. Also, if you encounter fuel-cut while you have nitrous engaged, you will create a condition that is extremely lean, moreso than normally pegging the tach. If you want the ability to damage your engine with the push of a button, feel free to avoid using anything like a window switch or fuel pressure safety monitor.
You don't need gizmos to shoot a gun, just a pipe and a nail. The rest of the system is for safety, repeatability, and reliability.

The Zex controll box "should" have a built in TPS activation (WOT) switch. In my opinion, TPS is the best way to controll nitrous activation. Just down load the install instructions from the zex website. pretty simple to install.

Most new kits come with either a mechanical activations switch or a TPS activation switch. a "mechanical" switch is just that mechanical. a TPS activations switch reads the voltage from your TPS sensor, when your TPS sensor is at "full throttle" it sends a signal to open the nitrous & fuel solnoids.
I believe Zex sells a separate TPS box that allows you do to that.
If any Nex or NOS or other No2 Users could help out by posting some links of Window Switches/Tachs/other stuff I might need that be awesome!!

Everything you ever wanted to know about nitrous and nitrous kits but were afraid to ask.
Zex does sell a seperate TPS switch but when you puchase a zex kit I believe you get this switch. I purchased my Zex from a buddy (older kit) and it had the TPS and solnoids inside of a box. I only had to hook up 3 wires (power/ground/TPS) and I was ready to rock.
