I have a question and haven't seen it answered.

I have UTEC, tuner reg pro and the 5 map selector (which is mounted in the open slot next to the seat heaters).

I assume that the UTEC nitrous community has a separate map in use when spraying. If so, what do you do if you want to spray at, say, 50mph as a cobra comes up next to you? I'm sure that you aren't pulling over, changing maps and trying to catch him. And I'm sure that you aren't spraying all the time, so what do you do?

Is there a way to hook, let's say, an NX system up, where 1) you can spray anytime you want to using your standard NA UTEC map and WOT controls, etc that come with the NX system, and 2) use a different map where UTEC fully controls spray on retarded timing?

Thanks in advance for your replies.

 

Hey bro, welcome to the n2o world. This is what I would do.

Have your good NA map that you use all the time. You can still spray on this map. You just have to make sure, if you use the UTEC to control it, the selinoid is enabled. What this means is that you will have to meet the following conditions:

n2o armed
utec selinoid conditions met (it, rpm, pressure, heat whatever you set)

Thats it, youll be spraying on the cobra that wants some.

That being said, set up a n2o map with retarted timing. Call it n2o or whatever you want. This is the map you use when your at the track or looking to lay down good times. This might be the map you use with race fuel, slicks, etc. The same conditions have to be met, just the settings you have in are different (ie different A/F ratios, retarded timing, etc).

Remember, you dont HAVE to have retarded timing to spray. Its done for performance and security measures. If your only going to be running 100 shot or so, running on the street without retarded timing isn't going to cause any problems. I think Jeremy has run as high as 125 without retard. The engine is strong enough to take it. However if your going to be running alot on a shot like that (ie several passes at the track or on the street) you would want to use your retarded timing map. If your just crushing some chump from stoplight to stoplight, no worries.

Hope that made sense =)

 

It did...Thanks Nowell. I'm not there....yet.

So there is no need to have the NX system installed like any shop would install it on a car w/o UTEC? You know, using WOT activation switches and the like?

EDIT:

One question. It's OK to drive around with N20 NOT armed if your UTEC base NA map contains N20 parameters?

 

Not sure what paramaters you would have on you NA map that would be different from your n2o map. The only thing that would adversly affect the engine is the timing retard, and that doesn't hurt the engine per say, just runs like crap =)

As for the install there are a few things you can do. If your using a WOT switch (like the zex box does) you can still have it hooked up, and then hook the n2o arm to the utec selinoid. Basically all that would do is wait until the paramaters that you have set for the selinoid are me, then the n2o would arm. Or you can have the WOT lead hooked up to the selinoid, which would then wait until the utec paramaters are met, then would complete the circuit, firing the nos.

Either way, you wont damage your car by driving around on a different map and not running the nos, or running the nos on your base map, etc etc.

 

I used the word "parameters" to only suggest that my NA map would contain n2o attributes. I haven't hooked the laptop up to see what n2o options exist, I assume that they would have to be added under the "boost" option.

Is this right?

I'm hooking the laptop up tomorrow, so maybe I'll make more sense then.

 

even better how about this.... you can switch maps on the fly as long as your rpms drop UNDER 1600. so i have my nitrous map on map 3. 5 degrees retarded timing. i let off the gas, switch map, turn on my nitrous switch and then leave a cobra by about 20 cars through 4th gear.... im kidding of course but the last one i raced was stock looking and i left him by so far it wasnt even funny



as far as your nitrous on all the maps goes. i have a seperate switch that arms the system when i want. the utec controls the extra solenoid on ALL MAPS. but if my switch isnt on it doesnt matter...

btw nowell. the most i ran on stock timing was 100 shot. i had the utec retard the timing after that.

 

Cool bro, I remember you told me you did, but didn't remember what size shot. I was just mentioning that it could be done without retarded timing =)

 

^^ I thought about this. Is there any additional risk of engine damage by putting your Z in neutral, switching maps, arming the n2o system, then shifting back into 2nd (assume that you were going 40mph)?

RPM's will go into the 5K range and I assume n2o will begin to spray immediately. This seems like it would be hard on the engine. But is this a reasonable scenario?

Also, how long does the n2o system take to arm?

Thanks for your time. My car goes in on Monday for a NX 100 shot w/ GenX 2 kit install. The installer is good and very capable, but isn't familiar with UTEC. They are going to call TurboXS to discuss with them how to hook the NX system up to UTEC.

I realize that this is supposed to be a quick and easy install to UTEC, but I appreciate the fact that the installer is willing to go as far as calling TurboXS for correct installation.

They also discussed hooking the kit up as they would on a car that doesn't have UTEC. This part I don't understand. I'm going to call them today, but any light you can shed would be appreciated.

here is what i say. go onto NX and NOS websites and read all you can about nitrous. also do a search on google and read read read.

as far as your question goes. it is fine to drop the rpms down under 1600 and switch maps. it is not bad for the car at all unless you have something crazy going on with your maps. nitrous can be armed whenever you want. it will not come on until you are at wide open throttle...

instead of really bothering the busy guys at TXS, read the manual a few times and see what you can pick up on. read the spare solenoid part A LOT of times if you can...

it is really really easy to hook up the nitrous to the utec and when they do, trust me, THEY WILL LOVE IT!!! if you know how to work your own utec then you can set up the parameters for the spare solenoid very very easily.

IN CAPS CAUSE I STRESS THIS....

tell them to hook up the red wire on the white plug to the ground on the RELAY to the nitrous/fuel solenoids. only the relay. then make sure to ground the solenoids as normal. (the utec spare solenoid switch controls the ground. NOT THE POWER SIDE LIKE NORMAL SWITCHES) then hook the black wire that is right next to the red wire, to the ground on the car. bring the manual for the utec and know exactly where to reference for the wires on the spare solenoid. when these guys understand how easy it is to set up a wide open throttle switch AND a rpm window switch, they will jump all over it....

 

Thanks guys... I have to delay the install by a day or two, but hopefully it'll be done by the end of the week.

 

Rob, who's doing your install? I'm seriously considering an NX kit while waiting for the twins.

 

PM sent

 

i'm doing twins w/ spray. 2 10 lbs bottles. its in the shop now.

good luck though man.
sounds great..

 

You really only need CO2 or methanol injection if you have twins. Post some pics when your car is done.

 

Dave Shiroma did my install...couldn't be happier with how everything came out.

 

How did the 2 10lb bottles turn out? Any pics?
