Default Question about active handling?

I'm pretty new in the world of corvette's but I just wanted to know is it possible to change the parameters of active handling? Is it possible to go into the computer and change the amount of time it takes for active handling to kick in? Reason being, I recently purchased a 2001 coupe and the active handling doesn't seem to kick in too quick. The former owner had done work to the car, long tubes, h-pipe, hi-flow cats, cam, and a few other little things, could this change it? I know that there is a competive mode ffor the active handling, but I have it in just regular and while racing my brother last night, just going threw second gear the tires lit up, the car came pretty sideways, and there was almost a couple of very unhappy people, if the two vehicles had touched. Luckily it was a near miss and I learned that obvioulsy second gear I have to roll on and not slam threw, but I would have thought that the active handling would have kicked in way before the tires ignited. Any help would be apreciated! Thanks, Dan

Normally TC kicks in very quickly. Remember, TC is only active in normal mode, and not active in the other two modes. If your sure the TC was on then it sounds like you have a problem. Check your codes and see if your getting anything related to the AH.

I'm not sure it's as simple as you're hoping, it's not a x ms and I'll do y, thing, it's related to the rate of change and the expected or anticipated behaviour versus observed.

In your case, perhaps your tyres are bald, perhaps they are mismatched to the car, perhaps the road was slippery, perhaps you made such a violent manouver that inertia won, perhaps, too, AH didn't work as it should have, but I'm not sure you've really said enough for anyone to know.

Certainly, if I try, I can put the car sideways but, then, as it says in all the blurb, AH can't overcome the laws of physics. Sir Isaac Newton still has it right, even in today's world.

Tires are newer, 80% tread, stock equipment run flats, road was bear tar, dry, flat with a very minor right bend, basically straight, traction control was on, ran threw first, tires broke, let off hooked back up, shifted second, hooked in second, gassed going threw second, tires rebroke into a hard spin bringing the car to a pretty good sideways. I understand what you're saying that the AH can't overcome all, but in a situation like this I would think it should kick in a little bit earier, but like I said, I'm new to the Corvette world and don't know how touchy these systems are, any help would be greatly apreciated.

There is a delay prior to the system kicking in, I can and have gotten my car all sideways with TC fully on and in competive mode.

Run flats explain it all. You're driving with no grip.

Hmmmm..... I sure would think the TC or Active Handling would catch that. I can see where you could do things such as turning a sharp corner at high speed that no computer could save you. But spinning tires, that's pretty simple. It almost sounds like it's not working at all. Have you tried just simply peeling out and see if it catches that?

I just got my vette and punched it to get back on the freeway quick after a desperate roadside whiz. I could literally feel the rear wheels starting to spin, then the correction. I believe it puts the brake on the spinning wheel. Seems like a good way to wear out your brakes!

I actually tried that the other day, unfortanetly I got caught out in the rain, damn weather people!!!! I spun the tires and it did kick in, it came up on the display, but it took a little bi of time, more than I would think that it should take. I just don't know if that's somethig adjustable when people start messing wit the computers or if it's a problem!?!?! Thanks for any help, Dan
