Any device available that will allow me to switch off stability control and keep traction control on?

 

called comp mode.

 

Actually, "comp mode" keeps the traction control off, with active handling on.

 

I have comp mode on my c6, but not on my c5 as far as I know.

 

C5 does. Hold the tc button 5 sec or so. The dic will display comp mode.

 

Well, actually no. Here's a GM press release on the subject:

"The Corvette Active Handling system will be the first of its type to offer dual mode operation. In addition to an "OFF" mode, in which Active Handling is disabled, the system also allows the driver to select a "COMPETITIVE DRIVING" mode for autocross or gymkhana competitions. In this mode, the Active Handling system remains fully-functional -- measuring steering, yaw rate and lateral acceleration inputs as well as applying individual wheel brakes as required -- but the traction control system is disabled, allowing for some wheelspin and oversteer that skilled drivers often find beneficial in competitive driving."

But my question was HOW DO I TURN OFF ACTIVE HANDLING AND KEEP TRACTION CONTROL ON?

 

You don't.

 

So you want to be able to slide and spin around, but not lose traction?

 

Like the commercial says, "makes sense if you don't THINK about it"

 

You two guys probably wouldn't understand, but I've been building and racing cars, bikes, and boats for fifty five years. I appreciate traction. I do NOT appreciate a nanny telling me I'm not steering, accelerating, or braking properly. If I want to throw the tail out in a hairpin, I DON'T want a computer tucking it back in.

 

Just push the TC button once and have fun thrashing the car around any way you want to.

 

That's what I've been doing, but I was hoping to get my traction control working with the nanny off. Kinda like posi-traction - I want both rear tires biting when I'm trashing!

 

A co-worker of mine with a '99 Coupe doesn't like the car driving for him,either-I told him he should have bought an early '98 like mine-no AH,just TC

 

The car has positraction without the nannies. Active handling will let you hang the tail out a fair amount and if you use it correctly it will let you do things with the car that you can't do otherwise. For instance, if you are coming off a sharp corner at about 20 mph and want to nail the throttle to accelerate down a straight it will allow you to put the pedal all the way to the floor, keep the backend from sliding sideways while the rear tires are spinning and just launch off the corner. Have done it and know it works. It keeps the back end in line by applying the front brakes back and forth to counteract the power oversteer as the tail moves back and forth. Doing it without the AH the backend would slide out and I would have to back out of the throttle. Everybody kept asking how I was launching off that turn so well. Got me FTD in 6 events.

Not saying it improves things all of the time but if you learn how to use it you may be better off. By the way TC will not allow you to hang the tail out in a hair pin either. It is going to cut throttle as soon as the rear wheels start spinning. All AH does is apply one brake. It does not cut throttle. Other than for show hanging the tail out in a hair pin is the slow way around the hair pin.

I suggest you go some place where you can put the car in comp mode and actually play with the AH to see how and when it activates and how it actually affects the car. Feel how it handles an understeer situation where you enter a turn too fast and then see how it handles the oversteer situation that can occur when powering out. It is a tool and is useful if you want to take advantage of it instead of thinking you are too good for it.

There isn't a situation where having traction control on but A/H off would actually help you if I read your request right - it doesn't modulate power between wheels like an ediff- it simply cuts power from the engine, something it sounds like you're not wanting.

 

I turn the nannies off

 

Thanks, Bill. Haven't done it with the Vette, but I cut nearly a second off my autocross times back in the seventies and went from fifth place to the championship by learning to do 180's in the hairpins. I HAVE found that I'm much more comfortable driving the Vette with the nannies off, but that doesn't neccessarily translate into better times!

 

That's what I'm doing for now. makes it feel more like my old 70 454, and I LIKE it that way!

 

Why not put a set of bias ply tires on as well...

 

I've had radials on all of my cars since I put them on my 327-375 fuelie powered MG-TF in 1965.
