Default 2005+ Traction Control- How Does It Work?

I read that the 07 Shelby can be run at the drags with the traction control on.(Hot Rod) I've also read that the 05 shouldn't be run with the traction control on because it changes the timing and air/fuel ratio to reduce power. It would seem to me that since the throttle is computer controlled, the traction control would just back off the throttle. I know the older Mustangs when the traction control kicked in it cut the fuel and spark so it acted like half the plug wires came off.
Anyway my point is, I am going to test and tune tonight and they don't prep the track on Tuesdays and I don't have my drag radials yet. On the street since I have put on my KB s\c I have no traction from a dead stop. Does anyone know for sure if the 05 traction control messes with the timing and A\F or does it control the throttle?

PUMPDOC is right. It actuates your brakes to equalize the spin of the wheels. If I were you I would turn it off though. With a S/C, unless you are really good at keeping wheel spin to a minimum, the TC is going to slow you down quite a bit. I have gotten to the point where I can launch with the TC on and it wont activate, buy im not S/C.

It does both. When activated, it uses the ABS system to stop the tire(s) from spinning as well as repositions the throttle body to decrease RPM's. Good information is in your owners manual. :smilie

I've spun my wheels for a second or so without TCS light coming on. I wouldnt think the computer would do anything until TCS was activated and means the light came on. So it doesn't seem like it would make a diff if I left TCS on or not when I'm taking off. Spinning your wheels = bad take-off anyway. So I think as long as a take-off only a little wheel spin with no TCS light, why not just leave TCS on?

I know for a fact it does more than apply the brakes.

With the traction control off I smoke the tires. Would be great for a freestyle burnout contest.

On the stock Mustangs, the traction control is programmed to allow a little bit of wheelspin on dry pavement for a straight line launch. It does not allow unlimited wheelspin though.

The traction control works both the brakes and the throttle as others have said. Every "all-speed" traction control system works that way because a brake-based system really only works at under about 25mph.

I made 11 runs in the 90+ degree heat. The slowest run was when I left the traction control on.
First run off the trailer 12.54 @110
After everything was hot it settled into the 13.20s spinning thru 1st gear.
Turned on the traction control ran a 13.41
Cooled everything down, the supercharger was so hot you couldn't touch it.
ran a 13.09 @ 111.39mph ,spun so hard the car got sideways.

Man I need some drag tires.

My guess is you probably lost a little traction.

First thing I do when I start the car (if it's not raining) is turn off the TCS
