What does the VDC do?

Snakes709

It detects any traction loss to any wheels. Once it detects the loss of traction it will reduce the engine power to regain the traction. Alot of people say its best to leave it on. Personally i hate the damn thing. Theres times when i liked having it on but more times i hate it, especially in the winter. I'll come around a turn, even on ice or snow i know how to take the turn. But the car will turn the VDC on and it will screw me up, causing me to go all over the place. That and when im trying to take off it cuts all the power and i cant go anywheres.

I was driving in the wet the other day and gave the car a bit of a spurt down a straight. The VDC actually gives a good degree of slip before kicking in, so it hasn't been too intrusive.

Going around corners feels a bit jiggly, but the VDC seems to let you do a bit of a slide before lowering the power output a little to bring you back on course. Relately, it's surprising how much grip the 370Z has going around corners even in the wet...

This is exactly what I have found. I see no reason to turn it off under normal driving conditions. Icy roads could be different.

If you have to ask what VDC does then you don't need to be turning it off.

I remember someone throwing up a link to an inline modual that allows you to turn VDC off and stays off even after turning off the ignition and start up again.

I tried the same spot same thing with it on.

On the 370z, when you turn VDC off, VDC is Off. There is no more traction control, at a minimum, verified by yours truly. You'll still see the orange 'slippage' light come on, but it's just warning you that you're spinning the tires.

I do straightaways with VDC Off. This lets me chirp the tires in 2nd or 3rd (and of course peel out in first), accelerate quickly and show off all speed related things my vehicle can do.

If I plan on hitting a corner at > the posted speed limit, or if it's raining, or if i dont' trust the road or the drivers around me, I turn VDC On. You'll know VDC is working by cornering hard: Your vehicle will hesitate or will be a bit sluggish to respond (talking 1/2 second or so) and when you try to spin the tires your vehicle will lurch, since VDC is removing power from the tires (read the manual for specifics).

Drive with VDC on until you get a feel for the vehicle. Then, slowly start practicing with it off. I took a hard corner on the way to work tuesday morning with VDC off, spun my tires while shifting to 3rd out of the corner and the arse end of my vehicle 'drifted' ~2 feet into the right hand lane. Thankfully, no one was there or i'd be one unhappy camper right now.

To the OP, did you know that your car came with a free novel? Yep, it's a freebie that Nissan ships with all of its cars. It's about a guy named "Manual." You should give it a read, it's quite informative.

I don't believe in reading manuals, it makes me drive too fast!

Quick doubt: Does having the VDC on affect the MPG significantly? Thanks.

With VDC OFF, you still have ABS and traction control active, just the VDC (as explained earlier in the thread) is off.

Traction control only operates at about 10% with VDC off, it will let you do donuts all day long.

You know there's a little book called the "user manual".

So I was reading Import Tuner today and they had the 370z 350z shoot out in there. During the article the one driver said with the VDC off, he had a hard time drifting the 370z around corners. So they had a 370z guru come in, he said that even though the VDC is off the traction control is still working. He also said in the article that if you want it completely off there is a little fuse you have to pull..
It is located under the center console next to the E-Brake.

Here are two pictures. One is for the Bosch Module so you can 100% turn off your VDC and the other is the fuse for the ABS. If you guys are interested in turning these two things completely off.
