I've turned My VDC off maybe 3-4 times in 5 years....pretty much for snow situations (low speed deep snow)

 

And THAT'S why I love my snow mode button

seriously wtf.

you personally must keep it on.

 

You're not pushing the car hard enough then. Even though you have an X, you should be able to get the rear end to slide a bit and VDC to engage.

and yes, turn off the VDC when autoxing.

 

Yeah, I was new and was getting a feel for the limits of grip in the corners more than anything. If I had some more runs that day I probably would have gone for some faster lap times.

 

Yes...I have one of those too.

Parallel parking in deep snow sets off the vdc too much. I turn it off because a little spin innthat situation actually helps.

 

I hope you're not doing this on the street. And especially not a busy street.

 

exactly, I dont have snow down here but thats what people need to understand, I get so annoyed hearing about people turning of VDC when they are driving in the snow...

 

My VDC was off when I went autoxing over the weekend... my slip light was on-solid at the end of each round.

I need to look at the DIY to fully disable it.

 

No offense, but you don't know what you're talking about if you don't have snow. I turn my VDC off every time I drive in the winter, and we get lots of snow up here. The VDC is just too sensitive. It kicks on with just the slightest slippage, either from a start or taking a turn. And it's not because of my tires (Nokians in winter). I've even considered getting one of KPierson's switches for it so it remembers my last setting (off). With it on, you just crawl until you get up to 15 mph or so. With it off, the car is an absolute monster in the snow. Who cares if you have a very slight fish-tail as you take off, at least you're moving. And turns are a blast, with no loss of control. In many ways, it's more fun to drive in the winter than in the summer.

If you're going to drive on all-seasons in a real winter, then you probably should use the VDC because you've already put yourself in a bad spot by not properly equipping the vehicle.

EDIT: yes, I have AWD, but my previous RWD cars acted the same, i.e. better with snows and the VDC off.

 

If you're going to dyno, burnout in a dig, or whatevers and need it to be fully off go do a few a doughnuts with VDC off and it'll shut down.. While keeping your ABS

You can pull the fuse but you'll disable ABS as well.. if you just leave it on with the sliplight on (dont cycle key) that's basically with it completely off while keeping


__________

I dont think there's any technical proof of this but this is just what I concluded from messing around with my car. When I was taking engine tuning classes I had my G35 on a roller dyno dozens of times and with the VDC disengaged it'll still cause problems either we pull the fuse or we wait until the VDC 'gives up' aka stays lit.. I guess the analogy is if it cant understand whats going on its just going to disable completely for your safety..

Hmmmm interesting... I'll have to test making it "give up"

 

It is a safety feature of the system. Basically you overload the inputs and fault the system to protect it if someone was to, say, get stuck in the mud and try to burn out of it without turning off the Traction Control. Prolonged application of the brakes, or reduction of fuel/timing to the engine can damage it.

Next key cycle resets it. Many cars have such fail safes because owners don't read the manual where it says in low traction situations it may be necessary to turn it off.


Not sure I like the idea of abusing the car to reach this point. I know guys with 03/04 cobras who permanently disable the traction control (via tune) because the vdc on those cars pulls fuel/timing. Slip a tire at wot with 600HP and pull fuel and you can do some serious damage. It's has happened. From what I understand, the g35 vdc also pulls fuel/timing as well.

 

You need to come take a ride with me.

VDC off can be VERY fun when done correctly and carefully. I turn mine off about 75% of the time, but always leave it on in inclement weather.
