nice reply :)

he will learn fast like all of us putting your foot down out of a junction and it kicks in.just take car not to put too much power down.

what were toyota thinking of with that system,surley they must know

YES!

 

:D

 

Infact I disabled mine so I couldn't forget to turn it off.

 

You can get TRAC removal kits from companies like HKS.

 

If you must have some Electronic TC then get Racelogic's system and we have the configuration info to get it setup better than standard.

The stock traction control isn't really much good, you certainly can't rely on it. As John says it's a matter of knowing when the 2nd turbo comes on line and easying off before squeezing the throttle back on again. Some people will tell you that the stock TC should be disabled all the time due to it being dangerous, but to be honest if you are driving in a manner that causes the TC to kick in and cause you an accident you've nobody to blame but yourself.

Yeah cause hitting diesel or ice is your fault!!! :rolleyes:

 

Its not about driving at the limit its about driving out of trouble...if you kill all the power to the wheels you have no way of controlling a slide.

hmm, I have owned a mkiv for about 4 years now and I still keep the stock TC on at all times. I work on the basis that if I can get the stock tc to light up then the conditions are too poor to push the car and so I keep off the power until I can be sure I can try again. I will be fitting RLTC at some point in the future as it was on my old mkiv and was quite frankly a god send in all conditions.

 

If you push your mkiv in the wet then you have to expect it to kill you, I learnt very quicky on my dads rover 827 that you never apply power until you are in a straight line (fwd, 2.7 litre engine, torque steer all over the place in the wet). I apply the same principle to the supra in the wet. And as soon as that trac light comes up its time to stop playing about.

 

I say keep it on, as the chances of most people being able to control an unexpected slide through use of the acelerator are slim. But do respect the conditions and do fit RLTC at the next possible opportunity.

Mine is on all the time as well. As JB says, when the light starts flashing, then it's time to realise that condtions aren't ideal for throwing your pride and joy around. I've never driven ( or been a passenger in) a car with RLTC, but the consensus on here is that it is the business.

Peter, if you are thinking of turning it off, may I suggest that you take your car to a wide open space (like an airfield) and try driving your car with the TC both on and off, and see what suits you best. :)

Well said JB and Gordon.....

 

All I ever hear on here 'turn the stock TC off' it is shite, it will kill you, blah blah blah......

Toyota designed feeking cars and all the nice things about the Supra, do you really think if it was dangerous to have the factory TC on the car would pass it's final inspection(testing) to be on the road!

 

Learn to drive properly thats what I say!

It's there for a reason...... use it wisely......

:eek:

 

If you can't judge the conditions and need the slip to kick in to tell you then...well, that's you're choice.

 

But personally I think its a cr@p TC which only serves to irritate or destroy.

 

If I'd had it on the other day when gently accelerating (20% throttle) in first, up hill, away from a set of lights it would have cut in cause the tyres started to spin. This would have killed the engine power and probably stalled the engine or bogged immensly 'cause it was only pulling 1,500 rpm up a hill - this would have resulted in a) embarracement b) someone behind ploughing into me. As it was I noticed the slip changed to 2nd got some grip and carried on up the hill. Lets face it TC is only good at stopping your acceleraton its NOT ASC or ESP (Anti-spin) it doesn't control the brakes just the throttle.

 

My way out of that little situation was far faster and effective than that waste 10kilo's in the engine bay!

 

I drive my Supra in every condition that hits these shores 'cause I have to. 20months 30,000+miles and no hiccups - touch wood - probably due to the fact I don't drive like a d!ckhead.

 

And also the stock TC cuts in too slow...you've already recovered sometimes by the time it kicks in, which is really annoying!

 

If you must have TC - and one day I would - get RLTC....end of - really can't believe you're defending the stock system. I've never had it on and had a moment where I've thought "wow I'm so glad I had it on"...have you???? REALLY? Have you honestly been in a situation where its been better on than off :eek: ? It can be a wake up call to the driver that's asleep but not one who's alert and on the ball.

 

Book yourselves in for some skidpan training then turn it OFF!!!! Bunch of Girls!!! :sly: :D

I don't think the stock system (UK spec) was that bad but it definitely comes in early which can be a problem when trying to overtake in damp conditions. I prefer the traction off and to feed the power (full throttle in the wet is asking for trouble) whilst expecting some slip and being prepared to ease off instantly.I had the traction on when I first got mine but have now removed the TRC fuse. I just prefer the chance every now and again to get sideways on my favorite wide roundabout. I would say try all the settings, find somewhere you can experiment safely and see what you prefer.

Yep, in both my mkivs I have found situations where it has helped. I have also found plenty of situations where I have been powersliding down the road and it didnt cut in so I learnt not to trust it to save me, only to warn me that road conditions were worse than I expected (never misjudged the conditions Alex?).

 

I do wonder at what point Toyota decided to fit traction control, I would have expected them to fit a really good system, and it does seem to be a last minute addition to the build. But I suppose it was 10 years ago now and traction control systems have come on a long way since then.

 

In order of how 'good' the stock TC is

1) import with no LSD - works well, senses single wheel slip, cuts the power, no chance of powersliding down the road

2) UK spec - applys some level of rear wheel braking to regain traction

3) import with LSD - quite happily powerslide down the road

4) import or UK spec modified - it will powerslide as soon as the 2nd turbo comes on line, just be ready for it, or dont use full throttle in the wet.

I'm with you there Branners, i keep it firmly on in the wet, if you turn it off and the 2nd turbo comes in before you know it you can be facing the wrong way down the road, it comes on in mine quite alot, dont want to find out what would happen all the time if it were turned off.

Settle down Alex.....

 

I have been driving 'legally' for almost 15 years now m8, drag, circuit, been there done that!

 

Read carefully what has been said my friend, No motor company would put something on the car that will be a danger to you.

That is my point, this is what everyone keeps saying, 'Stock Tc will Kill you etc etc it's 'dangerous'.

 

The Tc will only kick in for a reason, and the reason is because the car has lost traction and is unstable and uncontrollable.."which IS DANGEROUS".. not the TC.

 

The way the stock one works may not be as effective as the RLTC, but in some cases it does help..... remember not everyone may have the skill to correct a skid etc naturally, backing on and off the trottle as required etc, some panic, don't know what to do and in these cases the Tc can help these instances and people.

 

I am not singing the stock TC praises, I just don't think it's as shite as everyone claims....because in some circumstances it could well save someones life!

 

And as Jb pointed out AGAIN, if the TC has to kick in when you are driving..... controlablity is in question and it's time to go easy or be brave!

 

In summary, it's down to how you want to drive your beautifull car.....you may be the next Mario Andretti, but many are not, and these are the lives the TC may save!

So it is not dangerous and shite for everyone.....

 

Thats my opinion!

I agree to some extent with the pro use of stock Jap TC but it appears to have two levels of effect on the car. At the lower level you get a green flashing light and some reduction in power, which could be helpful in many situations. At the second level when the light comes on and stays on, the power is cut dramatically, leaving you with out any throttle response for what seems like ages. If you are in a situation where you need power but don’t have it then that is dangerous IMHO.

 

A good TC system shoiuld leave you in control of your car.
