the DSC tap- off vs the DSC hold- off theory.
 

im still trying to understand how the whole dsc turn off thing works ?

becuz when i tap off dsc i can burnout and drift and do donuts all day... ?

and when i do the hold off thing i can do the same thing also.. both lights light up tho.

u know what, i think the tap off method lets u do anything u want in the car UNTIL U MASH THE BRAKES.. then it steps in to get u back in shape.

becuz from what i remember trying to drift.. with the dsc tapped off, i would slam on the brakes anytime i would think i was about to lose it, and the car would quickly come back together and stop.

and with the dsc hold off, i would slam on the brakes when i think i was gonna lose it, and it would kinda do a "slide/ screech to a stop" not really a controlled kind of stop, just a apply all brakes and slide to a stop.

never actually tried to compare and test the 2 methods... but im starting to think that is whats happening.. what yall think ?

i doubt some of what you are saying, but here is the answer..

it you tap it once.. the

DSC light comes on. that means the dsc is turned off....

if you hold it down the DSC light and the tires slipping light comes on... that means the traction control is off...

i would try a track day.. mad sliding aint fast..

beers :beer:

Traction Control is not the same as Dynamic Stability Control.

You have a lot to learn there buddy.

I agreed, but sadly most 16 yr olds dont ...

okay... u didnt explain much....

from my understanding, traction control deals with wheel spin.. and dynamic stability control deals with handling manuevering of the car.. ?

so tell me whyyy... when i tap the button to turn just the dsc off, i can still burnout with nothing interfering whatsoever.. ? (traction control is still on, shouldnt that cut the power to the wheels ?)

i really dont see a difference between tapping it off and holding the button... unless like i said.. you apply the brakes.

thats my theory for now.... so someone please enlighten me and tell me whats really going on.

Try reading here. I had the same question... After pages and pages of thread, nobody showed me data on the difference.
I do experience the same thing that you do. To me both methods are very similar.

TCS = Traction Control System
DSC = Dynamic Stability Control

Grab your owner's manual and read pages 20 through 23.

TCS concerns itself with wheel slippage.
DSC is yaw control.
TCS uses differential data from the wheel sensors and tach.
DSC uses the above data and adds info from an accelerometer located just aft of your rear passenger cup holders (inside the console). The accelerometer measures yaw - the rotation of the chassis about a vertical axis.
TCS will modulate the throttle and, to some degree, the brakes to mitigate wheel spin.
DSC will also do the above, but has the ability to do so differentially (wheel-independent braking) to attempt to control spin of the entire vehicle.

If that doesn't explain the difference adequately, than you are not equipped to understand the use of the two systems to begin with.

okay.. taking from what u have above. and this is with the dsc off, what u have left is this becuz the tcs is still on:

TCS concerns itself with wheel slippage.
TCS uses differential data from the wheel sensors and tach.
TCS will modulate the throttle and, to some degree, the brakes to mitigate wheel spin.

now this sounds to me that since the tcs is still on... i should not be able to rev the car up to 5k, and leave marks on the ground... but i STILL CAN. so somebody explain to me while i still can ?

im not stupid.. so no need for the smart ass responses.. just trying to understand the differences.

OK OK OK ! thanks puch96 for the link ! that perfectly explains it right there in the first post of the thread.

so there is no actual difference between the 2 methods.. the hold method just tricks the system into thinken theres a fault, and the only way to reset it is restarting the car.

and actually, the button SHOULD be labeled "DSC/TCS off" :)

Quote:
Leaving the TCS/DSC on will provide the best stability. When the TCS/DSC is off, the TCS/DSC does not activate but the brake LSD function remains.

When you just press the button once, the brake LSD function (brakes still activate to steady the car somewhat) STILL HAPPENS. So technically, the TCS/DSC is off. Technically.

When you press and hold the button until you see the TCS/DSC light illuminate (car with squiggly lines) it shuts off the brake LSD so there's no intrusion at all in sprited driving.

Hopefully, that clears up your confusion.

-------------------------

THERE IT IS i knew i was on to something... the hold off method turns off the "brake lsd" causing absolutely no intrusion into the driving experience. yessss, i feel relieved

and they are both crap, the only time I've ever had trouble with this car was with the damn traction control "stabilzing me" backwards once. A competant driver can easily handle the read end stepping out, i do not need the car to 180 itself by braking for me and decide that driving backwards is accepable.

try it on a wet track with & without DSC then get back to us ;)

Hmm ... I'm thinking:

1) Drifting is driving out of control
2) DSC is designed to keep you in control
3) Ergo "tap off" might be good enough.

FYI, the antilock brake system has NOTHING to do with DSC other than DSC borrows its functions when needed to operate the brakes, and the antilock brakes cannot be shut off.

Also I think:

I'd be a lot more interested in conversing with you if you used punctuation, spelling and capitolization. I have an intense desire to ignore posters who talk in "IM talk".

I agree with Stew, your not pushing the car that far. I started with just the DSC off and still felt slugish in a corner, I couldn't push the extra bit if I wanted and do in my 7 often. When I read about the push and hold method I tried it and found that if your not expecting the raw feel it can catch you a little off guard as you can wurrr your tires more often around corners and such.

As for ABS I wouldn't recommend shutting it off without first have a great braking technique and a good feel for slippage since it can be very easy to lock the wheels up. I personally don't like it and the 8 is the only car I have ever had with it working, others I have pulled the nice ABS fuse and tossed it in the glove box.

If you just tap dsc off you will still have some assist when excessive body roll occurs. Has nothing to do with wheelspin. Noticed this autocrossing. Holding the button shuts off all assist. Holding it is the way to go. Anytime dsc interferes it slows you down.

It also saves your ass. I never shut mine off.

Only if your ass is asleep at the wheel.

Or you:

- Cross an unseen patch of oily concrete in the rain on an off-ramp
- catch a little black ice where you think there is only water
- Get caught out in the snow with your summer "shoes" on
- take a corner a bit hotter than you should

etc.

Totally, totally disagree with you. For everyday driving - on the street, in the real world, the man with his DSC shut off is a foolish man indeed. On the track, a different story, although for a novice driver it's a good thing while you explore the limits of the car.

If you are a well trained driver and not talking on your phone, eating a burger or blasting the radio, all of the above situations are better handled by the driver.
If you think you DSC does a better job of extracting you from trouble when you hit black ice or oil, gimme a call to warn me when you are going to be driving in the same state as I am.

In other words - if you believe what you said, you suck.

Dsc isnt gonna save you from black ice, especially if you're goin downhill. My point is, I think dsc should always be used except for track and agressive street driving.

Its an RX-8. All street driving is aggressive.
If spinning the car is a problem for the driver, using DSC to arrest it is just as bad as all these wealthy posers in their Ferraris smashing into parked cars.

DSC and TCS is an insurance policy. Of course I keep mine on most of the time. If it is ever active, its because I suck, not because it is needed.

I agree, for the lazy it is sometimes a get out of jail free card, but if you know how to drive the car, and paying attention it will be a hindrance.

I've said it a few times on this board, the BEST mod you can get is driving lessons.
