Noob question about TC...
Can someone tell me exactly what happens when you turn TC off? I understand the principle behind what it does in regards to limiting the amouth of slip you get, but does it actually allow you to go faster? I've heard a varying degree of things like it restricting the amount of fuel being delivered to reduce horsepower, to absolutely no change in anything but how the tires grip the road.
A good example maybe would be 2 cars on a dyno, one with TC on and the other with it off. If you have it off does it increase your torque, do you get more horsepower?
I've had 2 Corvettes in the past 3 years (01 coupe and now an 04 Z06) but have never played around with the TC settings. Can someone please shed some light on this for me.
Thanks.

Turning it off will not increase your power. Turning it off will, however, put all of the available power and handling under your complete control at all times. You therefore will need to be capable of making lightening quick and very accurate inputs as this is a production road racing car. Active handling works through the EBCM (electronic brake control module) first and foremost. It applies brakes based on a table and some computations from data contributed by sensors on the vehicle. With active handling turned off you are completely in charge of what the car does. There will be absolutely no intervention provided by the computer to try and correct your actions based on it's information. The only safety feature the EBCM will supply in this mode is ABS brakes. When the EBCM cannot overcome the situation by brakes alone it gets help from the engine control by adjusting various things which in effect reduce the power during the situation it's trying to correct. Competitive Driving mode (Holding the button down 5 seconds) will tell the traction control to give you a little more room to spin the tires, and a little more yaw rate, while still leaving the over all computer the ability to jump in if it deems appropriate.

I think it gives you infinite room to spin the tires. You can do a burn out without intervention. And if you blaze the tires in a corner, I think it only stops you because doing so causes too much yaw.

TC/AH is a fantastic safety feature on our cars. If you poke around the forum a little you'll find a few threads with folks trading stories about turning off TC/AH ending with some hefty repair bills.

Indeed. This is a production road racing car - and that carries with it a lot of adjustability to get it to handle the way that best suits your driving style. It also carries with it some heavy penalties if you get in over your head. My signature line pretty much says it all. I have to give my brother credit for that though. That's a phrase he coined after someone we knew hit the bridge at the end of the old back straight at Road Atlanta and didn't make it. If you're not up to the task, no one has to tell you that, and it isn't worth your life to try and pretend.

This may be a dumb question, but I'm only 2 days into vettes and my knowledge is near 0% about these great cars. Should the tc be ON or OFF if you were about to do a 1/4 mile pass at the track? In other words, which one will help get better ET's..

You can turn it off completely, but I would suggest that you leave it or or at least run in Competitive Driving Mode for the first times out a the track. As your confidence and skill build, you can then turn it off as you see fit.

Street= on. Strip= Competitive Mode (do you know what this is?) Roadcourse =Comp mode for more safety, off for advanced drivers and learning car control.
