Faster with VCD off?

msl82 · 04-16-2009, 09:05 AM

I could be totally wrong but,

Does our 370z accelerate faster with VDC off?

I thought I saw an article somewhere that they were able to get faster 0-60 time with VDC off...

I have driven with VDC off, and it feels faster, or am I just feeling the placebo effect...

I hate the VDC it spoils my fun. When its warm and dry out I shut it off.

It's not your imagination, it cuts power way too soon and aggressively at that. It's the worst traction control I've ever had.

I must say I don't know the answer to this perennial question - and I wish I did, because it has bugged me for ages too.

One of the functions of VDC/ESC/ESP (or whatever you want to call it) is to send signals to the ECU that tell it to reduce torque when it thinks the car is accelerating in an unacceptable manner. However, I have no idea what the criteria are, or when the system actually cuts in.

However, I suppose it's a fairly academic question, because every time I get in the car I start the engine, put the seatbelt on and switch the ESP* off!

Here's an interesting website - Robert Bosch GmbH - ESC

However, I'd still like to know because I too feel it may interfere with the car's performance - and I too wonder if I'm making it up!

*It's called ESP (Electronic Stability Program) in the UK, but it's the same as VDC.

All I know is I always turn it off if it's dry outside. I can take some slip in the rear - it communicates very well and doesn't fishtail. I can tell immediately when it starts to break loose, and usually it doesn't go very far anyhow.

Letting it break loose a little and continuing to accelerate is fine, but VDC immediately nerfs the power at even modest amounts of slip, which kills the momentum of the car. Although I suppose you could argue that's the whole point of VDC...lol..

Bottom line is unless it's rainy/snowy/icy, VDC is OFF, because it just gets in the way.

ChrisSlicks · 04-16-2009, 10:34 AM

The car is the same speed either way, on or off. However you can definitely drive faster with it off. Because the VDC limits wheel spin you can't get a good launch and it will also kill you on a quick change to 2nd if you chirp the tires.

I have mine off most of the time unless it's raining out.

Of course there's no power difference, but imagine it like this, no condom=

still the same act but oh sooo much better

Your explanation is the bestest!

Have you guys had any issues turning it back on? Seems like every time I turn mine off, the only way to get it back on is to shut the car down and start over again. The owner's manual says you should be able to just hit the button again...

No problems turning it back on. I've done it many many times. You should get that checked out.
Btw, restarting the car, does always automatically turn it ON.

I'm curious, I don't race cars or been involved in a time attack, i'm just a regular driver. Does VDC is really needed for someone like me(when its dry)?

k.alexander · 04-16-2009, 10:31 AM

Funny, I turn it off when it rains. Fishtailing through turns is just too much fun.

import111 · 04-16-2009, 11:44 AM

The 1st thing I do after I start the car is turn VDC off. Like others have said, it cuts power way too soon. VDC off is definitely going to be faster if you can manage the throttle correctly, weather it be in a straight line or on a road course.

chubbs · 04-16-2009, 04:14 PM

So what actually triggers the VDC into action when you're accelerating? Does it activate when it senses rear wheel slip, or can it activate before the wheels lose traction?

Having asked the question, I'm sort of assuming it's activated by the rear wheels slipping - does anyone actually know?

It's activated when it detects slippage.
