I was out doing some fairly aggressive acceleration runs tonight. Without the VDC you can do as big of a burnout as you want!! With VDC on the car felt real slow. Even shifting from first to second where it is really easy to chirp the rear tires, the VDC cuts power very aggressively. I think I'll be keeping the VDC off and need to figure out what I need to do to make sure it stays off unless I want it on and not the other way around.

 

Yup, every time. How can I wire it to be the opposite?

 

i actually like it that way...daily driving VDC is need dont wanna wreck....when i wanna race ..i hit the button and go...

 

You can turn of VDC and Traction with buttons, hit and gone.

 

i posted this a while back.

This switch is a normally open switch. Buy a normally closed switch and swap that for the normally open switch.

i dont have my car yet, so i dont know how many wires it has and which are which...

i will assume it has 4.... 2 for lighting it up, 2 for closing the circuit.(this is how my IS300 was). someone (i will when i get it) will have to figure out which wires are which. simple multi-tester would do.

here is a reference:

True, the switch is a normally open type... but there's a lil more to it.

It's more like a push button.
If you can hold the TCS OFF button when turning on the ignition, and manage to get it to turn off... you can wire a "normally closed" switch.

So by doing that... TCS will always be off when you turn on your car. However, if you want to use it, you need to turn off your car... hold the new switch when you turn on your car.

 

Now wait a minute! I'm confused. First we were talking VDC now were talking TCS. Which one is it. I would think that the TCS is what would slow you down (i.e. not let you chirp the tires) not the VDC. I thought that VDC (vehicle dynamic control) was only for steering and braking NOT acceleration. Raceboy, did you mean to say TCS (traction control)?

Don't get me wrong, I certainly defer to your expertise here. I just want to make sure I understand these things.

 

bonz:

i believe track (and touring?) only has 1 button (which is labeled VDC). the tcs is included in the functions of VDC on so equipped cars.

basically all vdc cars only have 1 button, which is VDC. non-vdc cars also only have 1 button, which is TCS.

am i wrong?

edit: i also think non-vdc / non-tcs cars (base model) have no buttons .... i could be wrong, though

 

There is one button to control both VDC and TCS. And I doubt it's as simple as using a NC or NO switch; it's probably just a momentary contact button that's an input to the computer. But I'm just guessing here. Who is the first soul brave enought to start taking apart their new 350Z?

I have mixed feelings about it: I like having it on for those times I goose it a bit too hard in a corner and it stops the tail from swinging out. But sometime on a hard launch, I feel it cut back the power and wish it would just let me spin the wheels and learn the limits for myself. I think I could program my brain to perform TCS better than the system, if only it would let me!

 

I don't understand, I have TC, and when I press the button it turns it off. Isn't it that easy to turn it off?

 

Yeah, you just have to press the button to turn it off, but it's on by default (when you start the engine), and raceboy wants it to be off unless he turns it on.

I wish you could turn off TCS and VDC independently, but I guess it's a tightly integrated system. Still, there could be different software profiles, one that allows tire-spinning as long as you're going in a straight line (which would be the same asVDC on, TCS off).

 

i never got around to doing it myself, but my friend's IS did not require you to restart car to turn it back on. you just pushed the button button. it is a momentary button like the stock one. i will get the radio shack part number.

and i dont know about that hold-turn on, release junk... where did you hear that?
