I was exiting a freeway. Upon entering the offramp, I was doing about 100 mph, and there was a sharp 120 degree right hand turn. I heal-and-toed from 4th into 2nd (actually engaging each gear - have you ever heal-and-toed over multiple downshifts?) and at the apex of the turn I nailed it in second. I was doing about 50 mph at this point when I nailed it, and I got the expected over steer. Usually AH lights up a bit at this point (front outside brake) to help straighten out the turn (thank you very much AH). But this time, I seemd to get a bit of oscillation left and right - the car seemed to fish tail left and right, and AH stayed on longer than usual. Though there's no way I could tell for sure, it seemed as if the AH was alternating between the left and right front brake.

Though I was not in competitive driving mode (meaing TC was enabled), traction control did not light up, as I am pretty good at this point at not lighting up the rears as I swing through a corner.

Has anyone else experienced this kind of swinging left and right, when the rears are *not* spinning (TC did not light up), and AH is doing its thing?

C5David:

Yes, I have noticed it very briefly under hard cornering especially when I am overzealous with the throttle. There are pitch and yaw sensors which I think sense the direction of travel realative to the speed etc. Then AH engages to correct same. I acutally had AH engage on me (I think) recently, going in a streight line under WOT. The car seemed to bog between a 2nd to 3rd speed shift. Only thing I can think of is that the ass end was going to step out, so AH applied the left rear brake or something. I seldom drive on the street in the comp. mode, mostly for safety's sake.

Just as a reminder, AH only works if the tires are hooked up. With TC on, that shouldn't be a problem, but I've noticed the 2001 AH is a lot more liberal than previously. It may just be that AH is adapting to your driving style and letting the car fishtail more before it steps in to correct things.

As far as bogging under WOT, that sounds like the classic traction control throttle shutoff at work; very unnerving if you're trying to beat somebody across the street or something like that. Having said all this, I drive with both systems on all the time, unless it's an autocross or similar event.

I've noticed that on hard cornering on a sweeping turn like freeway ramps I get what feels like a "hunting" of the front end. If I didn't know any better I'd think it was tread squirm. What surprises me is when the AH comes on when I don't feel like i'm pushing it that hard.

I was going at a good clip on some back country roads, 2nd gear with an agressive upshift to third (about 65 mph) when I hit some rolling type bumps, what I noticed was that the whole car seemed to almost die for an instant, when it landed I was securely planted and simply was able to resume under complete control. I have a 2000 Camaro SS, if I had hit those bumps with the Camaro the whole car would have shuttered and bounced, the active handling is awsome from what I have seen so far.

Jwight:

That's exactly what happened. The car died for a second, then caught again. Did not know TC could cut the throttle.

Dennis,

Was that you I saw turning left from 72 onto Shoe Factory last night... 9:30ish? Just curious... don't see too many Z06s on the road....

Jim:

No, that wasn,t me. The Z was parked all day. I have seen one other QS Z06 in the Elgin area, near Sleepy Hollow however. I do get up thru LITH on Randall Road sometimes. Have had some good encounters on Randall. Take care. /phpBB/images/smiles/icon_biggrin.gif
