So I want some 245 tires so I need to speed up the wearing out process of my 225. Its raining here so after class I went to an empty parking lot with one of my friends. So I press the DSC and leave Traction on. But I am confused because while doing donuts I am deff loosing traction. So what is the diff between that and holding the button down for 7 sec and turining off traction control?

There are some who say that after one push you disable traction control but only partially disable stability control .
I have yet to experience that - one push seems to turn everything off for me ....

Can of worms time

Hey.

There are <more than> a couple of threads from the past about this.

From my reading (unless you are doing dyno runs - in which case you need to pull a fuse), there is NO difference between pushing the button and holding it down for 7-10 seconds.

However, some have reported otherwise. I've yet to see proof that there is a difference.

^^ thanks for the threads, I didnt find thoes. Maybe they have the answer

Basically I feel that one push defeats TCS, Hold for 7 seconds defeats TCS and DSC. TCS cuts power to restore traction and DSC applies independent wheel braking to bring the car back in line. Now I believe the LSD plays a roll in this as well.

I did some testing on snowy parking lot and one push definitely allows me to spin the rear tires as much as I want but when you are traveling fast enough (I did 40 mph) and drift the DSC intervenes (you can definitely feel the difference). However with the button held down for 7 seconds, doing the same maneuvers resulted in no interference whats-so-ever at least up around the 40 mph I mentioned. Now, whether the system is still running and simply sets a higher threshold before intervening after one push or the hold (like at much higher speeds), that I haven't tested.

My observation is this in reverse. In other words, push to disable DSC and possibly lower TCS threshold, and push-hold to disable both DSC and TCS.

JRichter

I think this is certainly possible as the systems are definitely intertwined but have yet to get the car to cut power to the wheels with just one push during my little parking lot experiment. It's hard to test this at slower speeds so the TCS threshold could definitely be set higher with the one push. I'm sure when the DSC is working its magic it automatically cuts power to the wheels as well as applying the abs braking.

I agree that I haven't noticed a difference whether I just push the button or whether I give it the 7-second treatment. I do know that when it's snowy out it seems like I can rev the engine and spin the wheels all I want whether the DSC button is just pressed once or whether it's held down, so that would seem to indicate that the Traction Control System is completely disabled for both methods.

I've also done a lot of controlled sliding around snowy corners (though I've never completely lost control) but it would make sense that pressing the traction button would relax the Dynamic Stability Control system and keep it slightly active in case the rear end starts swinging around dangerously (instead of kicking in any time the rear end slides a tiny bit when it's enabled), and if the button is held down then both systems are completely turned off.

Just my guess

both me and my cousin agree that holdin it down for 7+ seconds makes the car feel different...

Someone call?

My experience in winter in the snow was that no button pushing would cut out any tire spin...and it felt like more than just power cutting. One push let me spin as much as I wanted, including with snow cables on the rears up a fairly steep hill. Couldn't do it with it engaged, one push let me spin and throw snow on the cars behind me like crazy and got up fine, maybe ~10mph ground speed, ~40mph rear tire speed for about 45 seconds.

Didn't disable it completely, but I did have to keep the rear in line the entire time. It wasn't correcting it for me.

Sorry can't help myself, it just bothers the hell out of me.

Loose == loose clothing, i.e. something not tight

Lose == to lose something, i.e. having something one second, and dropping it, you lose it

Lose != Loose

Single-push disables DSC and TC until you trip ABS. Then it comes back in to keep you from killing yourself in what is obviously a dangerous situation. Single-push is really only useful for doughnuts, burn-outs and trying to get initial motion started on snow/ice.

7-second push makes the system think there's a malfunction and it won't turn back on until you cycle the ignition. This is for racing and getting yourself killed.

I've verified this on goofing off on gravel, snow, and while autocrossing.

Thanks for this.

From everything I've read (and the contradictory stuff everywhere) - This might just be "The Answer".

Brettus ---- your thoughts?

All I know is you can launch faster and go faster shifting from 2nd to 3rd gear, if you do turn off everything with the 7sec push of the dsc/tcs button and launch at 5k rpm.

Im Going To Try It!!!!!

instead of destroying the tires you have just as an excuse to buy new... buy new and save these incase you ever have a blow out or need a back-up set to replace these should something happen and you're in a pinch on $$.

just a thought.

scroll down to the dcs/tcs section. also an overall good page.

the traction control cuts fuel to keep the rear from spinning the tires due to loss of traction...

the dynamic stability control applies the brakes when the computer detects that your input and the direction the car is going is not kosher...it helps to correct normal mistakes and save your butt by bringing the car back in line...

word of advice however...in any competitive situations or HPDE's...TURN THEM BOTH OFF!! (Hold down the button till you get the lights on the dash to come on solid)

Reason being that they tend to interfere at the worst possible time and your reaction to counter the "surprise" might just send you somewhere you do not wish to go...

Funny I just turned off my TSC+DSC and the car was definitely different. Slides, breaking traction, xtra power, it was all there.

ZumnRx8

In my last post i said i was going to try it.!!!.......(never knowing how to turn of Traction control only DCS...always thougt it was a fuse to take out) so theres this corner 2 blocks from my house i say about a 85 degree turn...or so..always take it hard since i got my car....(fuel cut off ruining it..but now i know the secrect)....so i slow down to 35 ish taking it wide....downshift.....and then whip the steering wheel hard right....and full gas ......sliding ....i mean TOKYO DRIFT...for about 10-20 feeet.....with a slight left jerk to straighten out.....man....never in my car have i felt that...........but after all this i think i need to get sway. bars strut front and rear and cross braces to tighten my ride before i start warping the **** out of it by doing this **** daily....

Funny thing...i let my boss drive it and he kept going in circles trying to get them loose....DCS off but not traction and we could never figure it out....everytime he would try fuell cut off would come on.......gayl.....i aint telling him now....cuz if i would he would be buying me new tires....

definetly 7 sec hold to turn everythihng off until engine off then on again reseting everything....

There's such a thing as a comma, it's used in the place of "......................" and it makes reading a post significantly less painful

Hello everyone - new member here, 2nd RX8 (first was a manual, forced to trade for an AT after having a severe foot injury awhile back that disallowed from using left foot; AT RX8 vs NO Rx8, I chose the '10 AT :p ). So the other night, I was merging into traffic on 95 - the roads were wet from rain and I hydroplaned a bit, rear kicked out. The funny thing is that I have a Sport - no DSC. However, when it kicked out, I got beeping and a flashing dash light, and reduced throttle. I'm confused. No DSC button anywhere, supposedly not installed on my car, yet I got the beeping and the light when this happened. Has this happened to anyone else??
