VDC off???

ChrisSlicks

Well if you are at a 45 degree angle I don't know what it will do but at lesser angles yes it does seem to. Perhaps not as a result of any stability program but rather stopping all wheel spin will return grip. It seems to apply the brakes intelligently in corners even with VDC off in that you can brake as hard as you want and it will never upset the car.

If I understand how the ABLS work correctly, it seems to me that it only apply brakes to the REAR to limit wheelspin under power. If you go into the corner at 80mph and jerk the wheel to one side, I am not sure if the brakes will actually kick in to slow you down or straighten it out.

When you apply brakes while the car is sideway, I think it is the EBD that steps in to apply brakes at the correct corner. It is not the actual VDC

ChrisSlicks

That may be true but regardless it is distributing the brake force intelligently using the same input data as the VDC receives.

Even if it was the EBD that is engaging the brakes, it is still helping straighten the car out. Why else would it apply brakes at a specific corner other than to stabilize the car?

That's what it is suppose to, part of drivers' aid.

I will pay more attention to it when I take it to the track this Friday. From my autox experience, I only see the light flashing from time to time. I honestly don't think it does anything for me, but then the lot we run are so pathetic that we rarely see over 55mph

Q8y_drifter

Yeah and that's why I'm trying to figure out what's needed to shut this feature off and just let it brake normally during a drift.

Disable the ABS and you should be able to take care of the issue.

Or don't drift and drive straight?

cossie1600

ABLS never kicked on at track, I think the LSD does a decent enough job to not let the car do a one leg burnout. It seems like the problem is more autox related where you are in the lower gears. You can't disable ABS by pulling a fuse, they are wired together with bunch of other stuff.

ChrisSlicks

ABS has it's own fuse but the fuse module also has the VVEL and Power Windows. You can get a replacement fuse module and then just cut the ABS fuse in the module.

I had ice mode/ABS problem at bumpy corners, but it's a lot better on smoother surfaces. I really thought about disabling the ABS at first, but I am not sure if modern cars really like that idea.

On a separate note, you can see how the VDC flash like a xmas tree no matter what I was doing at the track. The system is annoying on the Nissan, way too intrusive. My Prius has a nice stability control system

ChrisSlicks

Yeah, I did my first morning track session Saturday with VDC on. No matter how smooth I tried to be it just wouldn't let you accelerate out of a corner at all despite there being lots of available grip. VDC off and the car was great. Surprisingly the VLSD held up okay and I was able to rotate the car with the throttle.

The car didn't do a lot of one leg burnout (maybe once or twice coming out of T1), but a LSD would help quite a bit coming down the fast corner. I think that is one mod that is definitely worth the money, much better than wasting money buying stupid things like slotted rotors/calipers etc.

I lapped over 5 or 6 seconds slower with the VDC on.

1. Nissans do have the secondary traction control.
2. It will NOT prevent you to do any kind of slide unless you touch the brake pedal during a slide.
3. Why would you apply brakes during a slide unless you know your about to eat sh!t?
4. 40-50 mph 360 degree circle drift was no issue with my G35 and taking some 90 degree turns with a slide it doesn't look like the Z has an issue with it as well.
5. You do NOT need to worry about the ABS fuze unless you are trying to do a complete standing burnout where you have to apply slight braking for the car not to move and just burn tires.
6. If people are complaining about any traction control kicking in with VDC off then you should not be doing any sliding because 99.99% you are touching the brake pedal one way or the other during the slide which is pretty dumb in any car.....

i actually think our VDC isnt half bad. coming from an IS300, the Z is leaps and bounds better.

cossie1600

try a bmw porsche or even the one on my prius, the vdc on the z sucks
