VDC engaging under acceleration?
 

I've noticed that if I'm rolling around 4000 rpm in 2nd or 3rd with the 6MT, if I quickly go WOT, I see the VDC indicator light (swerving car icon) flash for a few seconds. I don't feel or hear any wheelspin/tires breaking loose or anything of that sort. Does that seem normal? What conditions cause the VDC system to activate?

Is VDC on?

If the vdc is engaged, theres some slippage occurring that the sensor has been triggered though sometimes one doesn't think there's no slippage their might just be some. I've had this happen of idle merging onto a freeway from the light that controls traffic flow at rush hour...

Yeah VDC is on the times that I noticed the flashing. If I turn VDC off, the swerving car indicator doesn't flash. Would clutch slip trigger the VDC system?

yes its normal.

probably between shifts?

No, this is not between shifts. This is happening during WOT straight-line acceleration. A slipping clutch wouldn't cause a sensor to flash the slip indicator light would it?

Yeah its normal. Although you may not notice it, this prevents you from chirping your tires.

It will also engage in other situations such as if you accelerate quickly while overtaking another car.

I wouldn't suggest turning it off. In my experience with the VDC off, I quickly saw how the rears start to kick out a little bit when I went over a slight bump on the freeway while quickly overtaking a car. A noob problem since I came from a fwd car previously.

No, a slipping clutch won't activate the VDC. If you turn it off and do the same exact thing you will probably spin the rear tires a bit. That's the whole point of VDC; to stop you from doing that.

It's just so damn cold out at the moment that the tires don't have a lot of grip. It is very easy to activate the VDC in 2nd, 3rd and if it's near freezing even 4th. The VDC is very sensitive to wheel spin and will kill the wheel spin before you even know it happened. My light was doing a lot of blinking this past weekend, temp was around 38 degrees. In the summer I find it a little aggressive at times, but in the winter or the rain it can definitely save your ass.

So true, I have 13,000 miles on my stock tires and they are almost bald (got new ones on the way) and the VDC comes on alot now as I punch it. Between the cold and no tread it comes on real easy.

I've only had the car a few weeks, and it has been sitting in the carport for most of it due to the nearly 50" of snow the last week, so I haven't even read the manual cover to cover yet. I had (have?) no idea where the button is to turn of VDC, but it made getting out of the carport a bitch. Just enough snow had packed under the tires that ice had formed in front and in back... every time I got up almost enough momentum while rocking, the VDC kicked in and shut down the revs. The disable happened long enough that I didn't have any juice to work with by the time the car was swinging back the right way.

I ended up having to chip away at the ice with a straight hoe.

Stupid Maryland weather :(

VDC on/off is on the left of the steering wheel.

Thank you, sir :)

Though since the S2000 is the winter beater now, I'm not sure how much I'll be driving in the snow anyway... probably in the rain, though. Gotta get the TT kit ordered!

I've experienced this too. I don't feel any loss of traction but I do feel it was about to when it does kick in, I mean your are at WOT! Anyway, I trust it does its job. If it wants to kick in early its just looking out for my safety, I'd rather have the system anticipate it, instead of after the fact. Especially or a slippery surface.
