Vdc slow to react on wet and snow

Pharmacist

The vdc reaction time seems to be a bit slow under low traction conditions. If i drive on rain or snow and i accelerate a bit hard i noticed the back can drift a bit before vdc kicks in and brings it back in line. Has anyone else noticed that?

I turned mine off and it's still there... that's my problem with VDC.

Pharmacist , VDC hates you because of your old Avatar.

i thought pharmacists were suppose to be smart?

I don't think they study vehicle dynamics in pharmacy school.

Pharmacist -- The reaction times of the VDC system are the same in the wet as they are on dry pavement. What's happening is it's just taking longer for it to reign in control of the car due to the low traction conditions. It's a lot easier to regain traction on a dry road than it is on a wet one.

oh ok... i thought smart people knew everything.

No, the internet knows everything, smart people just read the internet.

Also, the rate at which you lose traction is a lot quicker in the wet than it is in the dry. Since there is less resistance on wet pavement, your wheels will spin more (or your car will slide more) before the VDC kicks in in the wet vs. dry pavement.

I do know about car physics. Maybe i didnt explain my point clearly. What i was trying to say was that vdc seems to have been tuned on dry roads and not on wet roads. So vdc response is fast enough on dry road but it underperforms on wet roads, which makes no sense because vdc is far more useful on wet than on dry roads and should have been programmed to respond faster. I found that sometimes the car goes sideways to the point i have to countersteer before the vdc lights even begins to blink

It does not underperform on wet roads. No matter how it is calibrated, you will always feel like it reacts quicker on dry pavement. That's simple physics as I explained above.

In any case, if you are forcing a situation where VDC has to kick in on wet roads you're driving too fast anyways. That's just common sense.

pharmacist - which tires are you running and size? hope not the RE050A sport tires... not in your sub-freezing weather in toronto.

then it's not the car, it's you that is reacting too slow to driving conditions... like forgetting to swap to snow tires.
