Really, and the ECU again adjusts to keep the MIXTURE right.

Still waiting for you to prove me wrong.

Hook up a consult to your OBD2 port and watch teh ECU readings when you spray on a dyno too.

 

Oh boy................

 

OK, so by your logic, I can pull the Vortech FMU off of my SC setup because the ECU will compensate. Why even bother sending one in the first place right?

Your ECU will compensate for closed loop operation, part throttle stuff. But at wide open throttle, your ECU is programmed with the fuel maps and everything. Nothing changes that unless you get a new chip. For little stuff like headers and intakes, there is enough headroom that you're not running lean.

But when you're talking about a 50 shot or higher, then you need to up the fuel pressure or add more fuel another way. It's that simple.

And I've installed nitrous kits, so I'm not just making up stuff here.

 

The stock FPR adjusts for the fuel, but the ECU still controls the MIXTURE. It changes within a millisecond to correct it when the NOS is activated. WHY the hell do you think JWT has ECU modules that connect onto a stock ECU to help it adjust MORE than factory defaults. Factory defaults can only adjust so far. That is why 50-75shot kits are safe with a stock car. SX7R can do it whatever way he wants. Don rusn 12.2 off nos, and he never HAS blown a engine like SX7R has and another person in Dallas. I shall not go there.

There are many types of kits you can install and different ways. Direct Port, to dry kits right in the intake plumbing. The correct way is to have the MAF read the info FIRST before letting it go into the engine. Your asking for trouble the other way.

 

Hmmm from se-r.net:

Here is the dyno chart of Project SE-R with JWT's 100hp NOS.

This is JWT's ECU controled automatic NOS system that uses only a single fan jet and solenoid. The JWT system uses a seperate independant daughterboard and E-Prom to control engine functions under NOS operation. When the system is enabled the ECU looks at CAS signal, TPS and MAF voltage. When WOT @ 4000 rpm is detected the ECU will automaticaly turn on the NOS solenoid and kick the injectors up to a higher duty cycle to provide inrichment. The ECU will also retard the spark. The factory rev limiter is maintaned by the ECU. This makes for a pretty safe system.

Due to it simplicity, it is also the easyest system to install. The stock injectors can be used for up to a 50 shot. For more than that, bigger injectors from a 94 or later turbo Z or Q45 must be used.

Why do you think they mention MAF voltage? Because the jets are before the maf to get the correct reading. THE CORRECT WAY to install a kit.

 

OK Russ, whatever you say. Since you've found a way to change the open loop mode without a new chip, you know a lot more than I do. And thank you for showing me that a stock Maxima can't handle more than a 50-75 shot without a new ECU.

I've installed a direct port kit, I know how they work. Would you please explain to me how they get away with adding nitrous and fuel after the MAF? Wouldn't the poor ECU be too confused to work any more?

BTW, look at the JWT site. The picture they show of their nitrous kit has the nozzle spraying after the MAF on the 300ZX they feature. Give them a call and explain to them what you've explained to me so they see the error of their ways too.

 

Pssst... Russ...

The NOS website says you're wrong. According to this page:

http://www.holley.com/HiOctn/TechSer.../NOSTech1.html

The extra fuel is delivered by increasing fuel pressure when the system is activated. The ECU has no control over fuel pressure.

 

I originally posted the first thread about the nitrousmini system. However, I wonder if the person that just bought it off of ebay is a member of maxima.org.

 

I'm STILL not getting involved, but to answer your smoke-screen.

JWT has ECU modules that COMPENSATE, ie add extra fuel, by increasing the injector pulse width, so you don't need to go with SKY HIGH fuel pressure.

The raising of Fuel Pressure is why DRY kits max out at 100+hp, where as WET kits can go much MUCH higher since they don't need to raise fuel pressure(as long as the FP can support), ON STOCK FUEL SYSTEMS.

You can only run so much fuel pressure on stock fuel injectors/rails before you go static. With LARGER injectors and an ECU to control them at idle(ie JWT systems), you don't need to INCREASE fuel pressure to get extra fuel.

 

Wait a minute. Those nitrous mini systems guys are acting shady. When I went to their website the other day. The price was like $99. Now it's $210! Did demand just suddenly skyrocket?

 

Yeah, to some unsuspecting ricer.

 

 

you're just mad cause you're loosing the Ebay auction, no Mini NOS for joo!!

 

 

checking in....

 

since 3 people are telling russ he is wrong..

i think its time for.. um..

 

if i know russ.. he is basing his information off someone elses setup.. if my guess is correct.. he is basing this off Don's Nitrous Setup with JWT Daughter Board and NOS controller.. if i also know russ.. he is calling, faxing, emailing.. sending morse code for Don to come and prove you guys wrong..

until then.. lets just sit back and wait

 

awww fck it.. why not 4 in a row..

 

Yes, I have a feeling Russ is collecting his ammunition, but since he's CLEARLY mistaken, he may be gone awhile.


to me! to me.


Just playing Russ.

 

i was on the train when i got your email i am home now

I could spew my 1 1/2 years of Nitrous Knowledge in this thread.. but then it would like..

a) i was telling Russ he is wrong because i am picking on him.. (yes he is wrong)
b) i didn't know what i was talking about
c) repeating everything you, jeff and ben already said

 

 

He does tend to just run away when the evidence against his ranting starts to pile too high...

 

oh he will be back.. ither with more BS.. or someone to prove his point.. in a nice lenghty post

 

Well, I don't believe I was 100% wrong, but I was somewhat wrong. Hmmm, obviosly even after installing a few NOS systems and learning from others, I don't know everything there is to know about NOS. But still, this kit I was talking about for the money is still a good investment for some cheap, reliable hp as long as the SHOT isn't that big.

No, I didn't go to Don Sprint.

 

 

Very well said, Russ.

I'm so PROUD!

Next time I tell you NICELY that you are wrong, pleeease don't take offense. You know your shiiit, but we all *** the pooch every now and then.

JooO need to just admit when wrong ONCE in awhile or the hounds get thristy for blood.

It's been fun. Later!

 

oh ****.. the world is coming to an end..

 

yeah this is very old. I posted this last week.

 

Last week is "very old"?

 

OMG!!!! Who let Russ install their nitrous kit?? This thread is too funny.

 

Russ is probably talking about how Don's kit works. The way that system works is by no mean is the same as other dry manifold kit.

 

stubborn

1. u refused to believe you were wrong even after numerous members told u so.
2. u refused to believe actual information and took your "friend's" install as the benchmark.
3. even after everyone proved u wrong u still won't admit that you're fully wrong...just partially wrong..hey buddy if you're wrong..you're WRONG!
4. the fact that you do not know how to correctly install nitrous kit on someone's car is quite scary.
5. DO NOT EVER COME CLOSE TO MY CAR OR I'LL SHOOT TO KILL.

so russ time to do a recall on your install job and drill another hole infront of the MAF?

 

Now your telling me I don't know how to install a NOS kit on a car? lol!

I have installed 4, none of them have had problems. I must be doing something right. lol!

 

well you're doing partially right...not 100% wrong.

 

Lets see here..

99 Camaro z28, Been installed for 3 yrs. Installed before the throttle body, only place we could put it on his, no problems. He runs 100 shot, 550 hp to the wheels on spray. My first install actually.

01 VR6, before the maf, stock air box, no problems.

Altima Auto 00, Before maf, in cone filter pipe, no problems, runs
14s.

95 Camaro V6, before maf, no problems.

 

That statement seems 100% wrong to me. You can put the nozzle wherever you want as long as it's before the TB.

 

someone insert cookie pic.

does that make u a professional nitrous installer? no
does that mean it's installed correctly? maybe

but the members proved that you did in fact installed them incorrectly..do not justify to me/us that since the car is running ok that it's installed correctly.

you'll never shut up until someone proves u wrong. like i said partially wrong or not..you were wrong...be a man and admit that.

 

Nah, its okay. I listen to people with YEARS of experience before others. Don has years of experience, Mike Kojima has ALOT more experience with Nissnas overall. He puts it before the MAF on Se-rs and that is whats recommended over there. MUST be a reason for that.

But to you guys eyes I am 100% wrong when I am not. You can do it either way, whatever pleases you. I rather have the ECU notice all the sensors changing than JUST ONE. It's safer.

 

What sensors does the ECU "notice" when in open-loop mode? It's does not continuously adjust the A/F ratio at WOT.

 

Ben, put this thread out of it's(MY) misery pleeease!


Samurai lock hai!
