VDC off???

VancouverZ34 · 08-21-2010, 11:35 PM

Today, I was trying to drift my Z and I noticed even when VDC was off, VDC light blinked as my car was losing grip.
is there a way to completely turn it off??

Do what they mention in this thread and i believe you should be able to drift the z.
tested ms confirmed - "stop lamp" fuse pulled = stand still burnouts allowed

That just prevents power cut while braking. I'm not sure it will accomplish disabling the ABLS function that the OP is experiencing.

ABLS is part of the ABS system, and I believe you pull the ABS fuse to get it to deactivate completely.

You need to disconnect the module located under the e-brake cover. As mentioned this will also disable ABS.

I hope this wasn't on a public road...

I don't think anyone got firm answer. With the VDC off, does the car still apply brakes to limit the wheel spin in the rear? (as indicated by the slip light going off).

I have been doing okay with the annoying light flashing, but is it actually robbing power off the turns?

It only blinks, there is no control once you turn it off, hence people doing doughnuts and whatnot.

Also, a better option for disabling it permanently is to buy a reverse module someone on the board sells. So, when you start up the car, it's off, and you have to push the button to turn it on. Much safer than pulling fuses that kill your airbag.

Yes, but the ABLS (not ABS) is suppose to act as a LSD even though the VDC is off. Is that the case (which means it is robbing some power)

.

If it is blinking it is active. If VDC is turned off the slip light will only blink and activate when there is a large differential wheel spin. It doesn't cut power but it does pulse the brake on the corner with the highest wheel spin. Most people don't notice it because the slow down is slight, i.e. if your wheel is really spinning that bad it really isn't propelling you forwards any.

It happens to me on track with cold race tires coming out of medium speed corners (70-80 mph). It doesn't really bother my situation but I could see it being a problem in a competitive style drift scenario.

Does the "stop lamp fuse" mentioned in the other thread prevent the the VDC from kicking in when you brake while drifting? With the VDC off, I noticed that if you push the brake pedal (even the slightest) while the car is drifting to slow down, it feels as if VDC kicks in and adjusts the car's position and reduces power/applies brakes to the rear.

The stop lamp thing limits power output regardless of traction. ABLS is a semi traction control. I guess it makes sense why this car doesn't do the single wheel burn out off fast corners

There are 2 issues at play in your above description.

1st is the brake/throttle interlock. This car cuts throttle input if you touch the brake. The stop lamp fuse should address this.

2nd is the ABS itself that works in conjunction with the stability control. Touching the brake has a tendency to "straighten" the car out. I think you would have to pull the ABS fuse to correct this.

Yup that's exactly the issue here. Even with my foot off the throttle, mid way through a drift if I wanted to slow down, pressing the brakes even lightly would straighten the car out, as if the VDC was switched on again.

Does removing the ABS fuse disable the Bosch yaw sensor? I really don't wanna take off the center console all the time.

It does, but the car has a natural rear bias in the braking system so without ABS you will easily lock up the rear brakes. You would have to find super wimpy pads to put in the rear.

are you sure the car will straighten itself out with the vdc off? with vdc off, only the abs and abls work. abls doesnt really stop your drift, it just limit wheel spins. no?
