Driving home from billing last night in the wet was "interesting"

 

Didnt help that was running conzult at the time and was trying to get as broad a spectrum of responses as I could, flat out acceleration in the pissing rain is not a good thing:)

 

So, traction control, couple of Q's

 

Is Race logic the only one on the market?

 

Will it work with NOS? As far as I am aware it works by cutting fuel pulses, would that leave me with nos flowing? I know you shouldnt be using Nos in any situation that you need traction control, but things happen. And was thinking more of the launch control, would it bugger up a progressive nos controller?

 

Any help?

No there are a few other traction control systems out there. Race Logic is said to be the best.

 

 

There are a few ways Traction Control can work.

 

1. Apply brakes. But you will fry your brakes and is not as effective.

 

2. Cut injector pluse. This acually stops any fuel going into the engine helping you to get traction. Very little if any damage occurs to the engine. This will only cut the fuel and not the NOS.

 

3. Cut spark. The fuel goes into the engine but is not ignited. This will work with NOS systems but could damage your engine.

 

4. Accelerator Intervension. This will work with electronic accelerators, but the idea of a computer taking it over is not a welcome one.

 

 

 

You really need the cut the spark system. I dont know if Race Logic do that though. Email them and find out.

 

How does the progessive NOS controller work? Does it go off speed or revs? If its revs I cant see why launch will mess it up. Launch is more than just a 2nd rev limiter. It controls a progressive slip percentage to gain maximum grip.

 

Why you want NOS away? Have you already got a boost controller?

On the subject of NOS - is there anyone out there who uses it AND had declared it on their insurance for road use?

 

No I thought not ! :D :D

 

What happens if you wrap it, do you have to strip out the NOS kit before the loass adjuster pays a visit??

Know what you mean Jock - the journey back from Billing was "eventful".

 

The Racelogic system can be set up to cut the spark, but you will need the optional "Spark cut interface". Not sure about cost so probably best to ask them for details...

 

Cheerz

srrae- dont have a boost controller (didnt think it would help on an NA:)). Progresive Nos works over a time basis, it bleeds in from your chosen percentage power (30,40,50%) up to full power over your chosen time (1-10 sec).

 

If it cuts the fuel, I would imagine that I can put the power to the pulsoids in the same loop, thus cutting standard fuel, nos fuel and nos??

 

Soon find out as a kind gentleman on Ebay has just sold me his "in the box" RLTC for 295 of your best british pounds :D

 

Nigel, in the case you mention I would imagine the best thing you could do is remove the nos, or, as I plan to do, install a "hidden system in the first place. As it happens tho, when I insured my zed I was not asked about modifications to the car, and when I specifically asked about it , was told that they were "not interested if I had modded it" on the basis that if you have modded your car, and it can be proven that the mod caused the accident, they wont pay out anyway. Same was said about dark visors on crash helmets a while back, wear em if you like, but if it causes an accident or contributes to it, the insurance company wont pay for your damage and will try to recover third party damages they do pay

I'd be interested to know about hidden NOS systems - have you done the research? ie costs for install, running, performance, risks etc?????

I don't think you're going to be able to do that quite as easily as you suggest..

 

The RLTC is wired into all 6 of the injector lines (you did buy the RLTC for a 6 cylinder car, didn't you? If you bought one for a 4 cyl then.. er.. oh dear!) - i.e. there is no longer a direct connection from the ECU to the injectors, it goes through the RLTC.

 

The RLTC box doesn't kill all of the injectors simultaneously, it kills them cyclicly (actually, that's configurable, so it can cut from 1 to 6 injectors at the same time, depending on how much slip it is trying to counteract).

 

I'm trying to think how you could wire up a circuit.. I guess you'd have to wire something else into all six injector lines, that will only allow the N2O injectors to fire if any one of the fuel injectors is firing..

 

God only knows what that would do to your N2O setup, though..

 

Hmm..

 

Is your NOS wet or dry? If it's a dry setup, then I think it'll be fine (as there will be no fuel, just NOS, which is just like putting air into the cylinder - there will be no firing, lean or otherwise).. If it's wet, then you'll need to kill the supplementary injectors (not the NOS, necessarily, though you might as well kill both) otherwise you will get a lean burn (assuming the NOS fuel injector injects enough fuel to support any burn) when the RLTC kills the main fuel injector.

 

HTH,

Nige, am slowly becoming an expert on NOS :)

 

The whole hidden thing is about rather than having a 'kin great blue or silver bottle sticking out of your boot, and multi couloured tubes and wires sticking out of your engine bay, I just thought it would be more sensible to pug it away, I think a nos bottle or two smaller ones would look better in the spare wheel bay, cos who uses that yellow abortion anyway, and the piping can be done in black, tucked out of the way with the injectors going in the underneath of the TB intakes, that way you dont loose your boot space, and anyone having a look at your engine wont be able to tell what you have in there, not to mention the fact that all the anodised/ coloured bits cost a lot more. IE the difference between a polished alloy bottle (150 -200) and a steel bottle (35)

 

Admittedly there is a weight difference, but we are talking in pounds here, I personally would rather have a few more pounds in my boot (never a bad thing in a RWD) and a lot more in my wallet anyday

Aaron,

 

Am planning to build a wet system. And yes I did buy the RTLC for 6 (actually 8) cylinders.

 

The other option may be to cut the rtlc through the NOS arming switch, so that if you arm the NOS it kills the TC, not ideal I know, but I would rather that than have my engine blow up cos the two rreacted badly

One point, traction control works but cutting the power to the engine, or making the power drop to a level where traction is gained again.

 

If you use a normal TC and it cuts the injector, will there still be enough NOS injected to still cause a wheel spin. Only a little bit of NOS is injected at once, so will that small amount still be enough to keep the wheel spin going? I dont think it will.

Stuart,

 

the TC cuts the fuel to the cylinder, but not the NOS fuel supply, which is the problem. If the TC dtects slipping, and cuts the cylinder supply, there will still be a nos fuel supply, and a nos supply feeding the cylinder. These supplys will keep coming until you take your foot off the throttle (presuming your running a WOT system).

 

It is a common misconception that NOS is a single small injection, it is a constant feed, controlled by your throttle position, or a timer, depending on your system
