+1 if you were on advans then there was your problem.

 

i bet if you'd a stayed on the gas or let up easier, she'd a held just fine.... you came off the gas to quick which made you steer to hard and you lost her butt... i dont acd was the culprit, listen to warrtalon

 

I don't think the ACD had anything to do with it. You sure there wasn't any diesel on the road or something like that? If there wasn't any, it's just lifting off the throttle. Most you can do is very slightly modulate it or keep it constant. If you were on a motorbike, you would have high-sided...

 

sounds like throttle oversteer to me, i doubt the acd was an issue, the cold environment probably didnt help much either, im guessing your tires were probably hard as a rock and werent biting the floor, anyway, why on earth did you have it on gravel?

 

If you keep your Advans on past Halloween in Chicago then you're taking your life (and your car's life) in your own hands! A set of AVS Winter tires is probably cheaper than your deductible.

 

1. classic lift throttle oversteer.
2. stock Advans get hockey puck hard in low temps.

 

Life off oversteer ... happens to a lot of new AWD drivers who lift off instead of keeping a steady foot on the gas ... If you go to a performance driving class with someone experienced in AWD you'd probably hear the instructor yell that to you a few .. hundred times .. "DONT LIFT DONT LIFT DONT LIFT" ..

I learned the hardway back in 02 in my wrx spun out in teh canyons .... Nothing damaged - but understand what that feeling is completly now ... Sicne then no issues! And yeah I don think its ACD related !

 

ok, first of all, under NO circumstances would i have used my stock advans...i have michelin pilot sport A/S which work really well in the snow for me, and do good in cold dry temps as well.

so wartalon was wrong about the ACD? i dont think that happens often...i know he really knows his stuff.

i understand that i should have not lifted the throttle, but my ACD point was this: if you are turning with either gravel or snow mode activated, at a certain point during that turn, the ACD does SOMETHING, whether it is lock or unlock the diff...in my opinion, that could disrupt the car at that time. mind you it would have to be a pretty long turn, but that is all.

 

It will open immediately upon wheel turn but will also start to lock the differential when it starts to realize that the front wheels are rotating faster than the rear, it will start to lock so that it can match the front wheel speed to the rear wheel speed. I think I explained that correctly but if i didnt let me know.

This thread by Terry S. explains it all and in part C. How the ACD works is where I got this Im just not 100% sure if I explained it correctly from the way Im reading it.

 

Thats the same thread I pulled the quote from as well. What I gathered from reading it is that in Tarmac mode the diff opens upon steering wheel input to allow the front and rear wheels to spin independantly so you dont get the skipping effect going around the corner. The wheels in the front have to travel a greater distance than in the rear so you wouldnt want them to be locked. The two other modes, gravel and snow, the ACD delays the time that it frees the center diff...

I think it only locks when your going in a straight line, if it locked the wheels while turning, things wouldn't turn out good. The acd can sense when your going straight or if your turning.
