this is a complete kit to disable your vdc completely when you need it off

Interesting.

 

I did the exact same thing with $5 worth of parts from radio shack.

 

Write up a DIY than.

 

I have one of these, best ever that off.on.off.on blows!

 

I don't understand? Their is the button over the left side of my knee when I turn it off. I know their is the way to turn it off completely but what difference does it make? Can some one explain?

+1 on the DIY from Taurran!

 

Xx SIFaKa the difference is that the factory one wil eventually kick back on if
the vechile is under extreme condition. this will totally disable it under any condition until to reactive it

 

+1 on DIY... I'm an EE so I'm sure I'll have no problems doing it, but I dont know enough about the car to do it my self without doing alot of research...

I.E. How do you fully shut the VDC off and keep it from comming back on? Does the ECU turn it back on under extream conditions, and if so, how would you circumvent that? Is the switch that is pressed in the dash a simple pulse, so the ECU turns the VDC off, or is it a switch that actually stays connected when pushed once, and then disconects when pushed again, etc... I guess I could pull my dash apart with a volt meter and osciloscope to try to figure it out, but if you already figured it out, it would be awesome to know what you know already!

 

i read this on another thread recently:

Completely Disable all computer assistance:

1. Open the hood ("bonnet" for our Aussie/Brit friends)
2. Open the battery compartment cover
3. In front of the battery is a fuse box. Look at the top of the fuse box and you'll notice the fuse positions are labled, with one labled "VDC". Note the fuse layout and the position of that fuse.
4. Open the fuse box.
5. If your fuses are the same as mine, the one in the VDC position should be a red fuse with the number "50" (meaning a 50 ampere fuse) on top. Remove it.
6. PUT THE FUSE IN A SAFE AND EASILY REMEMBERED SPOT!
7. Close the fuse box.
8. Close the battery compartment
9. Close the hood
10. Drive the tires off the car without any interference from a computer.....but BE CAREFUL!!


BTW, I ran this buy David M (editor of nissan sport magazine) at a recent track day and he didn't seem to think it was necessary.

I haven't tried it, but if you give it a shot and see a major dif over VDC off switch, let us know.

Thanks!

"It will turn off VDC every time you start your car, while retaining the functionality of the VDC button".

 

I don't know if we are all on the same page?
The little unit that I have only rememberer's if the VDC is "off or "on". If the key is shut off it will return to that off or on setting...I leave mine off all the time, before the module every time I got in the car I would have to reach down and turn the VDC OFF. Now If I Turn the car off with the VDC off, re-start the car the VDC will still be off. If I want it on press VDC SW.
This does nothing more then remembering the last setting of the VDC.

Actually, what I said was that totally disabling VDC might not be the best idea for the majority of Z owners. Turning off VDC (with the cockpit button) disables some of its functions, but not all. Even with years of racing experience (and with plenty of laps in my Z at track events), turning off VDC gives me the ability to rotate the Z slightly and go faster at the track. But that is purely dependant on your driving skills! If you overcommit, VDC (on or off) will not save you from a spin, crash or any other act governed by the laws of physics.

Maybe the question should be: what is it that you're doing that you need VDC totally disabled for? If it's truly meant for speed, I would bet VDC would save your a$$, rather than be a hinderance.

I remember testing this theory at La Junta!

 

Thanks for clearing that up David; sorry I took your comment wrong.

The impression I came away with was, 'don't bother, the VDC on/off switch is plenty raw', which I agree with. I grew up driving rear wheel cars that pre-date any sort of driver assistance so having the VDC off really isn't a big deal to me. I am curious how much more 'raw' the Z gets with the fuse pulled. Definitely something I will try on the track next year (I've only had my Z for half a year and I'm still getting use to having a rwd car again).

Anyway, I just offered up that fuse pull info so those interested can decide on their own. I’m sure more than a few other Z owners out there are like I am grew up driving rwd cars in snowy states and actually ENJOY getting a car sideways. I love looking out my driver or passenger window as I slide sideways through a turn...

 

I like that analogy made in the previous SportsZMagazine article.

Turning off your VDC is like not wearing your seatbelt. There is no point of trying to throw your seatbelt on right before the accident happens.

 

Meh, I don't think those are the same.

Seatbelts are fine, everyone should wear them.

VDC is optional. If you have experience getting sideways, enjoy, if not, keep your skirt on.

 

I think skirt comment depends on the situation. IE: On the track and no hazards... I'm letting out my false D1 skills. On the road to work...

 

True true

 

Here's a quick DIY:

- Pull out your center console

- Look for the square bosch unit with a bunch of wires plugged into it, it is near the are where the coin holder would normally be located.

- Find the orange wire going into it, cut it and wire in a switch.

- Mount switch in coin holder or wherever you want.

- Put it all back together.

- When you flip the switch you will see the SLIP and VDC lights go on. This means it's working. VDC won't be reenabled until you disengage the switch and restart the car.


PM me if you have any other questions.

 

I tried to do the pull the fuse thing, and when I didn the SLIP, VCD OFF, BRAKE, and ABS lights all came on, and I no longer had ABS.... so I'm starting to think that's not really a good way to do things...

did that happen to any of you when you tried it?
