Diff between "Comp Mode" vs. Trac Cntrl "Off"?
What is the difference between hitting the console button ONE time (= Traction Control "Off") versus "Competitive Driving Mode" (per the owner's manual = "pressing the Active Handling button on the console TWO times within a five second time period")?
They both seem to accomplish the same thing = "allows the driver to have full control of the rear wheels" (while the Active Handling System remains ON in both cases).
So what's the difference between Traction Control "Off" vs. "Competitive Driving Mode" (one button press versus two button presses)?
Any explanation would be most appreciated!

I have wondered this, as it does seem to run a different map to me

Comp will let you slide it fair respectable. I would be careful about turning everything completly off on a backroad flogging. It wont hold you back on comp and can save your hind end. It has mine and several others have reported the same thing. This was the design goal with the setting and it works.

After my g/f lost control of our '99 after turning off the TC, I would be very wary of turning off the TC. The competition mode allows for a lot of spirited driving, but will save your butt should you let the cat out of the bag completely.

I make my passes in Traction System Off, that's one push of the button.
Allows wheel spin, but keep aggressive AH available should the rear get loose on the launch or shifts.
TS-Off has no adverse effect on straight line acceleration.

TC is off while in the Competition Mode, when you manually turn off TC, and when you disengage AH completely.

I believe he is saying " TC is off in Comp, mode. TC is off when turned off. TC is off when all is off. At least that is my take and the way I understand it. For normal "Sunday afternoon driving" I leave all on. When "out with the boys", I run in the Comp mode.

2nd press and release; DIC says COMP MODE = (TC OFF, AH REDUCED).
3rd press and HOLD; DIC says TC & AH OFF = (BOTH OFF).
There's no need to go thru the sequence above if you want to end up with TC & AH OFF; Start the car, press and hold the button until the DIC says TC & AH OFF.

I don't think TC is completely off in COMP MODE. I saw a 'traction control active' or similar message on my dic coming out of a tight turn at rockingham. It wasn't the 'active handling' message that comes on if you go into a drift coming out of a turn.

Traction control (TC) from the owner's manual: "operates only if it senses that the rear wheels are spinning too much or are
beginning to lose traction. When this happens, the
system works the rear brakes and reduces engine power
(by closing the throttle and managing engine spark) to
limit wheel spin."
Active Handling (AH) from the owner's manual: "The Active Handling System is a computer controlled system that helps the driver maintain directional control of the vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes."
TC is always on unless you push the AH button on the console. Any time you push the AH button to change a function TC will be disengaged. If you push one time, TC is off and AH is on (fully engaged). If you push twice in 5 seconds TC is off and Competitive Mode (AH partially engaged) is on. If you push and hold down for 5 seconds TC is off and AH is off. As I said, it's confusing!

"Competitive Driving Mode allows the driver to have full control of the rear wheels while the Active Handling System helps steer the vehicle by selective brake application. The instrument cluster light will not be on. The Traction Control System will not be operating. Adjust your driving accordingly."
