VSC

[3.1415926]

My '06 has Vehicle stability control. which is automatically on all the time unless you push the defeat button. Each time the car is restarted the stability control is on again as the default. I want to drive the car without the stability control on all the time but don't want to keep resetting the it each time I drive. I'd like some advice. Is this possible to defeat the default? Is it wise to do this? Shifting at V Tech revs gives me a little fish tail with VSC on, what will happen with it off?

Hmm...i thought it was called VSA...are you sure you own an S2000 man?

"v tech and fishtail with the "VSC" on?"
why would you want it off when you don't even know what it's going to do?

everything is wrong about this post!!!!

I thought all AP2 come with clutch delay valve that will actually delay full power to your differential (and rear wheels) for a second after vtec/red line shift, so you should not have any spinning wheels even with VSA off...

Are you sure you have AP2 S2K?

[3.1415926]

Sorry about the missed acronym. I was never much good at government work. It wasn't much of a fish tail, more of a lurch. Tried it again with VSA off but didn't experience the same effect- maybe I wasn't quite at the same rev.

OK dang it, VSC is Toyota. Subaru is VDC and Volvo DSC. When I ask a simple question I expect the person answering it will know more than I- Why else ask a question?

[kgf3076]

VSC has nothing to do with going in a straight line and everything to do with pushing the car beyond the limits of the car (and the driver). VSC (or VDC or any other of the acronyms) will detect wheel spin and either brake or transfer power to the non-spinning wheel (LSD's do the same thing so I doubt the VSC even bothers in a S2k). I doubt that the VSC had anything to do with the "fishtailing".
Just as a general question..was this fishtailing determined by a butt-dyno?

It was definitely a side motion or yaw but I guess you're asking if the car itself moved or just me. I dunno but it happened fast and that is what concerned me. I have had a lot of experience drifting way back when in my TR4- so I expect and would actually enjoy some motion on the corners.

Hey Pie I would sugest some more seat time in the car. To find its limits. If in fact you have an AP2 with the clutch delay valve and what not. I dont think the V whatever will kick in unless tires start spinning. It all depends on how hard you drive the car. Drive it smooth and Im almost willing to bet you wont even notice it.

Then again I have an AP1 as raw as you can get so. Im just used to the car.

Oh and if you have to ask if its a good idea to turn the V whatever off.... id leave it on.

[dwhale]

hmmmm. what is this clutch delay valve? I know that 04s and 05s don't have VSA... I have for certain almost spun out (on purpose of course) doing some sharp turns...

It's self-explainatory! Clutch delay value! What do you think it does according to its name? LOL

Yeah, my 03 can get as woolly as its wants. I have been sliding it around a bit here and there just to see what happens at the limit.

[desmo4]

I have nearly slick rear tires in Oregon where it rains all the time and the rear steps out occasionally which just keeps me sharp.

Its snap oversteer is pretty much determined by how good your tires are. I have crap tires right now (rear only) the Star Specs on the front. I could drift this thing if I wanted. Just when you get good rubber all the way around be careful (Least in the AP1s) cause man itll kill ya.

[3.1415926]

We'll I guess I'm old enough that I don't really give a shit if I sound stupid; I've learned a lot over the years asking stupid questions- but I don't understand why having good rubber results in "it'll kill ya". Do you mean that with old rubber the drift starts sooner and is less abrupt and that with new rubber things will happen too fast to react (this can be important when you're 63)?

I think it goes something like this, The better the car hangs on the more violent and abrupt the release will be. So if you have slick or hard compound, greasy tires that tend to let go sooner and more gradually than a good sticky performance tire would it will generate less cornering load.
While the better tires with more grip will build up a larger amount of force with an equally large release when you go over the limit. My buddy use to run on r-compound tires and he would comment on how it would bite you if you were not used to it. Harder tires tend to communicate more at the limit than the softer tires. You can feel them start to let go and back off before you wipe out but the softer ones stick and stick and stick then BAM! Hello Mr. Guardrail.

But I am not a tire engineer so I am just going off what I have experienced.

I have a new set of Pole Positions. They hold on fairly well but they wiggle enough to let me know when they are getting ready to go. Plus I have intentionally pushed the car too far to see how it reacts. Too bad we don't have the TOP GEAR test track to play on

The guy that commented right below you is quite correct.

A high performance tire would yield more grip which means more speed. Which means more G force applied. So when the tire does let go (which these tires tend not to work below 50 degrees The Star Spec Z1s) it is quite viloent and you have to counter steer quite fast.

Right now I am running a soft cheap tire and it barks and squeals like crazy before letting go and its completly predicatable. Where as the better tires give you little to no warning of whats about to happen.

Im not saying you cant drive it. Im just saying just get used to it first then turn off the V whatever. Typically with good tires you will get a hint of understeer before the oversteer kicks in.

I have logged 60k in the S in 2years. With different tires. The best so far I have driven is the Star Specs. However I do have an AP1 with a stiffer anti roll bar. They sofened the roll bars for your year model I believe which would change the oversteer reaction. Just saying know the car is all. Im sure you can drive it once ya got that.

TR4? Wow man, that was a little car fo sho. I had a Spitfire even smaller I think...
Enjoy going sideways :P

There is a way I saw somewhere. I dont recommend doing it though. Just turn it off when you want it off. I did a lot of sliding when I first got the car and I was learning it's limits.
And yes you can slide when banging second in an AP2. My first auto cross at the front straight I banged second and did the rest of the straight sideways. My instructor sitting next to me said "OK you dont have a problem with agression!"
I was hitting the far side of the short straight prepping for the left hander so actually it wasnt straight I guess.

Going back to his original question, I too am curious if there is a way to leave the VSA off instead of having to push the button every time. I wish it was the other way around, but oh well

Hey Doc, since we're on the subject, is it bad to crack your back multiple times a day? I have this crazy obsession where I have to crack my back a few times a day. I have this massage chair that I use daily and I love cracking my back afterwards. Just curious if that is going to cause major problems in the long run. I have a buddy who's also a chiropractor and he tells me I should be fine but I just want a 2nd opinion Thx!
