Competitive Driving Mode
Can anyone tell me what changes take place when you hold down the active handling button and switch to Competitve Driving mode in my BBB '03 Vert

Active handling will correct some driver error should the car start to get squirley, yet allow for a good burn out at launch.

My C5 ia a A4
When I brake hard at a standstill and WOT it shudders and shakes and the tach goes to about 1200-1300 rpm then drops back to about 950 rpm and the engine bogs right down. If I let off the brake I will get nothing more than a chirp in 1st gear and another when it shifts to 2nd and that's it... nothing more. I assume the traction control prevents spinning the wheels. When I switch to Competitive driving mode the rpm will go to about 1300-1400 rpm and when I let off the brake it will do a good burn, and get a good burn when it shifts into 2nd gear... So I'm going to ask the question again
WTF changes when you switch to Competitive driving mode. How do they acomplish this Traction control.
Years ago it was in the Differential with Posi-traction now it is controlled somehere else... Anyone know how???

If you exceed a pre set Yaw rate (back end comes out headed for a spin) opposite side braking is engaged to attempt to straighten you out, that is the active handling component.
When you switch to competition mode the yaw control is still active but the throttle retard is turned off.
Actually it is a bit more complicated than that but those are the essentials.

When you are in the default mode (Traction control on) you have both throttle retard and yaw control. When the tires reach a certain amount of slip the throttle is taken away from you and the computer takes over.
If you exceed a pre set Yaw rate (back end comes out headed for a spin) opposite side braking is engaged to attempt to straighten you out, that is the active handling component.
When you switch to competition mode the yaw control is still active but the throttle retard is turned off.

Thanks for the quick response My guess is that the engine management system (Computer) controls all this?? Is this correct?

Re: Competitive Driving Mode (Richin Chicago)
It's really a great way to "idiot proof" your Vette or rather protect yourself whenever you come across a patch of sand in a corner at an inopportune moment. :thumbs:
Matter of fact, I puchased a Trac-Activ Deluxe controller that puts my Vette in competition mode every time I start it and the controller even clears the DIC message - automatically! It's a great little mod for the Vette.

If you get on the throttle just the right way in a straight line you can haze the tires very nicely with Traction Control active. It is very dependent on how much slippage there is between the rear wheels and between the front and rear wheels. If the posi is locked up so the rear tires spin equally then it will allow more rear wheel spin than if one of the rear wheels is slipping a little more. I had this happen all the time with my 97 that only had TC and I can get my 03 Z to do the same. First thing is you do not want to much power. On my first drive in a Z I hazed the rear tires in second gear with just a quick increase from 1/4 to 3/4 throttle at about 20 mph. TC Active came up on the DIC but the rear tires were spinning.

Re: Competitive Driving Mode (markcz)
Actually you have more than throttle action when traction control activates. The first action is to apply the brakes

I had always thought that the brakes came on first also, but since Mr. Mercury had a problem with that I decided to look it up. This is out of my '01 service manual on page 5-206.

Active Handling stays on........ Traction Control turns off.
When I got the Hardtop smogged, I had to go to Competitive Mode to turn off the Traction Control. The guy said if I dont do it, the car might throw in a code since the front wheels arent moving on the dyno. I dont know how this applies to RWD cars on a dyno, but I know M3s and Porsche TTs do not like being on dynos where there is a difference in speed on front and rear wheels.

Re: Competitive Driving Mode (c5chris)
Boy am I glad that is cleared up... I was beginning to lose sleep over the question.
mrgil; are you sure that your listing is for the C5 system? It doesn't mention throttle-by-wire at all (which is how the C5 traction control reduces power to the rear wheels) ?
