any controllers? - Honda Prelude Forum

are there any controllers that incrementally inject nitrous based on RPM's. I'm still hoping for the idea that i don't have to press a button to inject nitrous. I would like a computer to do it without my thinking it.

here is the low down. pretty much any nitrous kit you buy will have a switch that you put in your car. you flip the switch to arm the system, and once it is armed then you will start spraying nitrous as soon as you go to wide open throttle. So in order to spray you have to have your nitrous system armed as well as be wide open throttle.

Now if you want to progressively add nitrous as your rpms increase, there are products out there that do that. Jacob's Nitrous Mastermind has a nice controller, but I *think* they discontinued the 4 cylinder version. NOS, NX and other companies have their own controllers, but be prepared to spend $600-$1000 for them.

Another solution is a window switch. What a window switch does is turn on at a certian RPM and then turn off at a certain RPM. So you can have the window switch to start spraying at 5000 rpm and then cut off at 7500-7600, that way your nitrous cuts out before you hit the rev limiter.

edit/ I would still recommend running the WOT switch in conjunction with any type of controller, there is no need to spray while you aren't WOT.

see here's what i don't understand. You can be at WOT and still be at 2k rpm, and that would make much sense. What i want to do is still use a wot sensor in conjunction with the controller. i would figure that it would just make more sense that along with WOT, it would be better to have a controller proportionally inject nitous.

how much is the NX maximizer or the mini max. The nos TPS controllers sounds good too, but it it compatible with NX?

Anyone?

Unless you are looking at spraying over a 75 shot a controller really isn't needed. You can use NOS controllers with NX kits since it is just wiring that connects it to the kit.

Doesnt the Mastermind Controller for V-8's still work for our cars? I was under the impression that there was no differance between the 4 cylinder MM and the 8 cylinder MM. Anyone know for sure? It the cheapest controller by far, and has all the functions you really need. Like Laughin said, if your not spraying a big shot, dont worry about it. If your having traction issues, drag radials would be a better solution.

It is recommended to spray above 2500 rpm, that way it doesn't lug the motor a lot. If you have a 5 speed this shouldn't be a problem, since you will probably be launching at more than 2500 rpm. You can also go WOT and then flip the arming switch when you want to spray. You aren't going to have big traction troubles with a 50 shot, so a controller isn't really necessary. If you really want an automated nitrous system get a window switch and set it up to spray at whatever RPM you want. Make sure you are in lowest gear possible too, that way you aren't lugging the motor.

I am selling my Jacob's Mastermind, works wonderfully, but NOS noids aren't up to the challenge. Has all the stuff your looking for in a controller.

Toretto · 10-04-2003, 11:41 AM

I like the window switch idea. And I though NOS cheater noids would handle a controller, am I wrong?

No way. You'd need cadnium seals to make it work and they don't even hold up as well to trash as NX seals do.

That sucks, so if your gonna use a controller, you would definately want to go with an NX kit. I wouldnt say NOS noids are junk though, i have ran my dry kit for a year now with no noids problems. I suppose if comes down to what you want to run in the 1/4. If your not gonna run a controller, then a 125 shot might be better than a 150. I would like to run 12's next year, and with a 125shot and dragradials I think its possible.
