VSA and winter

If you're stuck in a snow bank, will the VSA keep the car from spinning one wheel only (a bit like a viscous coupling)?

I don't know much about the VSA, but my salesman told me in a snowbank or going up hill in the snow, shut it off. You will continue to spin the tire that is slipping.

I cant say for sure..but based on what I know about VSA this is what I think would happen...

tires spinning is a traction control issue...and all the VSA will do is cut power. So it wont matter whethere its 1 tire..or 2 tires spinning..all traction control will do is take off some power.

Not quite. What you're describing is a limited-slip differential. As I understand it, in the scenario you describe, VSA will brake the spinning wheel and perhaps close the throttle a bit. The throttle modulation only happens if you're moving I think (understeer detected). If you're stuck in a snow bank or trying to start from a stop on ice, turn the VSA off.

I could be wrong about this ...but i dont think VSA will apply brakes in a traction control situation..that is..tires spinning. It will only cut back the throttle, so it wont do much if you are stuck.

So you mean our acuras dont have a traction control? Only systems to turn around over and understeer?

from Acura
The Traction Control System (TCS) component of VSA uses sensors that monitor the front wheels and computer-controlled modulation of engine power and front brakes to help prevent wheel spin when starting out or accelerating. If the sensors detect excessive front-wheel spin during acceleration, TCS automatically closes a secondary throttle valve until wheel spin stops. This helps the TSX maintain traction during acceleration and helps the driver retain steering control, even when accelerating on slippery surfaces.
C'mon guys. Have some faith (or just RTFM ).
