When I drive in any condition, there is no noticeable difference between having the DSC/TC completely off or just turning off the DSC. When both are on, everything works fine, TC light blinks and computer kicks in. But when I just turn the DSC off I never feel the TC kick in nor does the light blink. At first I thought it was the super shitty stock Potenza's, but just bought Goodyear Eagle F1 all-seasons and it's the same. I've tested this in light snow, rain, and frozen asphalt streets.

Can someone detail what specifically happens with only the DSC off.

By the way my car info: 2005 GT/purchased Dec. 05. 6 speed. 27k miles. No problems whatsoever except squeaky clutch, I know about the TSB but there are no dealers on the North side of Chicago(not driving to the 'burbs).

Thanks in advance.

 

You got to be kidding . Read the manual.

When you shut it off you won't get any IDIOT lights.

 

I can care less about the idiot light!

My point is that when I press the DSC button once to disable it only, I don't think my traction control is working but it should be. I haven't driven any other RXs so I don't know how good the TC works.

My question is what are the differences when only DSC is off vs DSC/TC off, same noises(ABS)? Up to what speed does it kick in or only in first?

 

turn off the dsc..

in first gear rev motor to 5 k and drop the clutch.. see what happens.. it will be obvious what traction control does..

beers

 

^when traction control is off, it is most noticeable when you launch at high engine revs >> you get rear wheel spin.
this translates to poor acceleration.TC detects wheel spin and applies breaking power to keep tires planted to the ground.

DSC works with traction control but also monitors steering angle and yaw rate. it applies both breaking power to the wheels
and reduces engine output to maintain ideal handling.

Traction control is restricted in most drag racing events because officials consider it as unfair technological advantage.
DSC is turned off in auto-x because it becomes a burden as it reduces engine output and slows your time.

During wet and slippery road conditions however, DSC/TC will prevent your car from fishtailing/spinning.

 

If the traction is supposse to bug down on power when loosing grip on backtires (with the dsc OFF) its fucked up in my car.

I notice no difference between the dsc-off and the "7sek button hold" ****.. =>

Excuse me if I totaly off now..

 

you are not an experienced enough driver to notice the difference.

 

I can't tell the diff either . One push and I can light up the tyres all day long - push for 10 sec and same thing ......

 

i don't think kersh4w means it as a low blow

But, the Dynamic Stability Controller (DSC) works in tandem with ABS & Traction Control unit. Both utilize the ABS system.

1 push -DSC off, so you can drift it without having the the DSC engage the rear abs.

2. 7 second hold. DSC & TCS light (Squigly tire tracks). DSC is already off, TCS will let you spin wheels all day long, not taking into account to over ride the electronic throttle position sensor. So it's at this point just man and machine, that being you, fly by wire gas pedal, and rear lsd.

for me i'm not sure if it's psuodo awareness, but i notice a slighlty better response time with throttle reaction with dsc & tcs off, oh and if your on snow or in a drift. the TCS light doesn't blink at you

Short version, yes go into a wide open area.. (Race Track Preferably)... max out 2nd gear, initiate a drift, and balance the throttle with just DSC off, you'll see the TCS blinking at you...... provided you are looking down... donutz can yield the same effect.. the TCS is there to moderate speed differences between the rear tires.

I haven't found a way to validate this, but i think the threshold is increased with DSC off, allowing a wider range for wheel spin, as long as rear wheels are spinning at the same or near the same rate, which is were the LSd does it job.

If you get heavy rain, you can also test this by hydroplaining your car, the TCS will kick in once one tire starts spinning faster, the LSD will shift torque the the slower tire, since by design it's suppose to be the one that has the most traction, while the hydro'd wheel will spin freely. So TCS will kick in on the the rear tires to manage the difference in wheel spin. So here is were it can get messed up, If you have DSC off while testing this, you can potentially go into a fish tale situation.... So how you wish to manage that is up to you.


end summery: The ABS, DSC, TCS go through a calibration on startup. and failed calibration on startup will trigger a CEL. And if it's not recoverable, the effected system will go solid and become innactive. ie: SOLID ABS, DSC, or TCS... DSC & TCS are reliant on the ABS, so if calibration on startup fails it will stay on. Not experiencing this myself, it would be safe to guess a blinking CEL light would occur.

Alot of this info is in the Manual. but for a peace of mind, if you have no CEL or any of the 3 system lights stay on after startup, they are functioning as expected.

later!

 

you should be able to spin your wheels with both.

no push - wheel spin, TCS light blinking.

1push - wheel spin, tcs blinking.

7sec push - both DSC/tcs off (light for both is on). wheel spin, lights are solid, no abs activity.


Really if you plan on spinning the wheels for drift or faster quarter miles, you should just have both off, your rear pads will thank you, and your ABS system will not mediate with the throttle position sensor.

Unlike the older systems, abs will engage the brakes if it cannot be remediated by throttle control. .... Z owners had a big fit about this (350z), when they thought they had it WOT, it was really only allowing 90% throttle engagement. Until somebody data logged there drive .

you WILL create premature brake pad wear spinning wheels with the TCS on.

 

with no push you can't get much wheelspin at all .
I have tried it several times .....

 

with no push u can get a bit off wheelspin and quite a bit of playroom when it comes to sliding the back out. I think it works quite well =>

 

I can tell you that I lost a drag race once because of it - just as I was changing into 2nd the back slipped sideways a fraction and one of the wheels locked up to bring me straight - other car got a full car length on me straight away

 

lol, Brettus i hope you didn't have $ down.

Yeah - the DSC is nice when your in lazy mode. i typically drive with the DSC off unless i'm driving on the cell or texting.... hey hey now! i've seen people try to take a nap while they're driving... i don't think texting and driving is any worse :P
