Are my new stiffer sways screwing with VDC?

ProfessorDave

Does the ECU "learn" suspension mods? Just wondering.

I agree with the advice to drop to the first setting on the bar. I've always found the softest setting on an aftermarket bar to be a HUGE difference over stock.

i'd also add that vdc takes time to act, if it sense a slip it will try to prevent it this is for small slides, but for big ones it will try and try but it wont just fix everything in an instant. i mean give it time and eventually it'll save you.

Jordo!

I doubt it. VDC probably just responds to wheelspin as it happens.

Yep. Responds based on monitoring wheelspin.


OP, you can usually mash on the gas and get the rear to step out pretty easily, even with VDC on. I think it's normal.

Mt Tam I am

If you mash it, sure. As I would have expected. As opposed to my surprise.
Oversteer, coupled with light gas in a tight uphill turn was my mistake.

Apparently the Z VDC is slower to react than other stability control systems. This is a good thing. Everyone would turn it off it was in nanny mode like the Prius stability control. That is the other extreme. My Prius would never let the rear end slip an inch. It reduced the throttle instantly in situations where I know I could have turned without loss of traction.

VDC works on each brake individually and on the throttle. The math that controls this is really complex. The car maker can make the VDC as strict or lenient as it wishes. I give Nissan credit for building a VDC that will keep me out of trouble but won't nanny me and turn driving into a boring Prius experience.

Pharmacist

Um, you were actually trying to drift a prius? Other than the lack of power, isn't it also fwd? How would the rear end spin in the first place?

Stability control doesn't only prevent drifting. It also limits speed on turns. Obviously, you can't drift with a Prius. It is underpowered fwd. But the stability control is so aggressive that simply turning a corner can trigger it.
