DVC really turns off??

I have no problem spinning the tires until the cows come home or making the back end overtake the front with VDC off. However, last weekend I was coming into

I have no problem spinning the tires until the cows come home or making the back end overtake the front with VDC off. However, last weekend I was coming into a corner during AutoX really hot with VDC off, and stopping the brakes got the back end loose and VDC straightened the car out. Also, when I did my 180 on track, brake application again immediately rectified the situation which was otherwise not really improving all that quickly (I was sideways until I hit the brakes and then I got the left-right-left-right-while-slowing-VDC-sensation).

Hmmm I don't follow you. If you hit the button, the VDC is off. The slip light might still flash due to the ABLS, which is a computer controlled LSD. It doesn't limit engine output directly, it just apply brakes to the wheel that is spinning. Nissan has a safety bypass that doesn't allow left foot braking, is that what you mean? The VDC doesn't turn itself back on.

No, ABLS remains on.

I dont know what to think.....but I can tell you I never hit the brakes when this happened to me yesterday. Anyway, tonight I made a u turn and got on it some and caught a nice fish tail and no VDC engaged at all! I was a little less agressive tonight with my girl in the car though, but still got sideways a bit and no net!!

Read your owner's manual

The VDC OFF switch is used to turn off the VDC
system. The VDC off indicator illuminates
to indicate the VDC system is off. When the
VDC switch is used to turn off the system, the
VDC system still operates to prevent one drive
wheel from slipping by transferring power to a
non slipping drive wheel.The VDC warning light
flashes if this occurs. All other VDC
functions are off, and the VDC warning light
will not flash.
The VDC system is automatically
reset to on when the ignition switch is
placed in the off position then back

You were doing a one wheel retarded burnout

What Cossie says or if you accidentally brushed the brake pedal and switch is not properly aligned. You may have triggered brake sensor switch that will put car in limp mode.

You triggered ABLS. Excessive inside wheelspin or even excessive rear wheelspin relative to the front wheels will active it and pulse the rear brakes momentarily. It can be disabled by unplugging the module under the center console near the e-brake.

I leave it alone, it almost never interferes with what I am doing and to trigger it on the street you have to drive like a maniac.

There are plenty of other threads about this. I can spin the tires at will in a straight line, doing doughnuts, drifting corners, ect., with the VDC off. With VDC off you can do what you want with the rear tires as far as throttle goes.

To clarify my point, the ABS system will reengage some form of VDC if you're out of control and apply the brakes. I was sliding 90deg sideways on the track at 70mph and had full opposite lock dialed in. The car wasn't doing what I wanted, but as soon as I applied the brakes she did the VDC shimmy and went right where I was trying to point her.

A second instance happened at my autocross last week. The fastest part of the course was a fast 'straight' that was actually a slight arc. I'd touch 60mph and then be hard on the brakes while still turning through the arc to then enter a hairpin. On one run, the car was very unsettled as I rolled hard into the brakes and the VDC did the stabilizing shimmy despite being turned off.
