Good on you...there are ways to enjoy your Corvette besides washing and waxing....congratulations! Be careful, you may have just created a 'monster.'

Comp mode is not the same thing as TC off. While it's true TC is off in comp mode the AH tolerances are greatly reduced allowing you to drift or slide the car more before AH intervenes. If you drove your car competitively on a road course you'd learn how essential it is to use comp mode (or to shutoff all nannies). Using TC and full AH on a road course is IMO dangerous...you expect the car to handle and respond in a certain manner but it doesn't. The system intervenes aggressively at the most inopportune times. Even when using comp mode on a road course you'll see the system intervenes often, however, intervention is much more 'relaxed.' It doesn't cause the drastic, negative affects of TC and full AH...the car is much more manageable and predictable.

Even if you're just going in a straight line a good rule is to always shutoff TC when going WOT (I'd suggest using comp mode). You do not want the system fighting your efforts to accelerate. If you need to feather the throttle do so.

Note: Learn how to drive your car in a safe, legal setting. Don't experiment with going WOT or with various modes on a public street. If all you want is a straight line rush, go to a local drag strip...most have regular test and tune nights. For a more complete driving experience get your car on a road course. There are numerous HPDE courses, car club events, professional driving schools, etc. in virtually every state. I suggest you search for NASA (National Auto Sports Association) or SCCA (Sports Car Club of America). These organizations sponsor well run and safe events. Have a blast with your car...really learn how to drive it but keep it safe!

 

then read the manual.


With massive grip, I run in CDM almost exclusively. I don't care for the electronic nannies and I know how to drive a car. With the big rear end grip, CDM is the better way to launch. I don't want the nannies applying brake to my spinning tires if I'm trying to launch.

And wolf, yes, you can definitely tell the car is a beast in this mode. All the nannies off and ready to go!!!

 

My A&A supercharged MN6 07 stays in regular mode (TC and AH on) all the time unless I want to do a big smokey burnout. With 577 RWHP you can spin the tires plenty and the computer really doesn't interfere because it happens too fast for the computer to react to it.

 

The first thing I do after starting the car is put it in Competitive mode, UNLESS the roads are wet, then all the nannies stay on. (Yes I drive it in the rain and hasn't melted yet!!)

SOOO much more fun in competitive!!

 

Hold that button down for five seconds or so.... turn EVERYTHING OFF. I call it..

You're on your own mode!!

 

He Drives In the Rain !!!!!!!!!

 

We are talking about the car right!?

 

Oh - I definitely understand that !

 

I do the same thing. Its best to have the same settings when you drive each time.

Much safer with the A6 in C mode. With the TC off in C mode you get a much safer launch with a car like the Vette that has such huge power.

The A6 will not shift right if you do a regular quick launch and the TC comes on.

Yes , in the rain all nannies on full.

 

As I understand it, the simplest explanation is:

1. default - the most nanny
2. tc off - less nanny
3. cdm - even less nanny
4. everything turned off - no nanny

Those who haven't driven a car like this very much should go with mode 1.

I do sometimes wonder how we survived all these years without AH

My C5 did not have it

Most of the time, I drive in mode 2.

 

I have owned my C6 for three months and had the pleasure on driving Palm Beach International Raceway as well as Sebring. I have normal performance tires on, so far. There are people driving faster than me for sure but I would say I perform reasonably well.

From my 100 laps on the tracks I must say "the nannies" are pretty laid back. Sometimes they help out a bit but so far only in situations where I am losing time anyway due to overdriving the car. If I am doing the right line, the car nannies have not engaged once. The posts I have read where electronics have made the driving unsafe or reduced pace is not what I have experienced so far.

I will let them stay active for next activity on Daytona.

PeO.

 

Back in the day we were just scared of our hotrods (at least enough, even at 20 years of age to have never wrecked any of my 8 cylinder cars). luckily my Z-28 had the usual amount of understeer stock from the factory

 

Luckily my Z-28 only had 230 HP

 

Yep . . . no "lectronic" helpers on the hot cars I grew up with either. That'll learn you pretty fast of the do's and don't's.

 

Why would active handling off make a difference? It only comes on when you are oversteering or understeering. That means the front wheels or the rear wheels are sliding sideways. If the front wheels are sliding sideways it applies the inside rear brake to yaw the car in the direction you are turning the steering wheel. If the rear wheels are sliding sideways it applies the outside front brake to yaw the car in the direction you are turning the steering wheel. However, if you are over or under steering on the highway you are pushing to close to the limits of physics. Not a good thing to do where a misjudgement could get somebody seriously injured.

I remember reading that in Comp mode the throttle is actually LESS responsive initially (more exponential programmed into it) than when everything is turned on. For those who are not aware, the throttle body does not open in a linear ratio to how you step on the gas pedal. 1/2 pedal does not open the throttle blade 1/2 way. GM did this so it would be harder to break the rear end loose coming out of a corner when driving the car hard. At least that's what a previous post said.

 

my first hot car .........i bought brand new..with my hard earned money..just got back from Viet Nam in fact. got a 67 Camaro......327.... blew the motor... after some mods, dropped a 327/350hp vette motor in it....... from there.. a 68 Chevelle SS 396.. 375hp.. did major mods, was turning mid 12's on the street... with Mickeys... yes.. i learned how to handle the power... and it was fun and scary........LOL its been that way all my life... but as I have aged, im thankfull GM jumps in with options to keep me safe now.

 

I did a 90* and crossed the center median (very lucky nothing was coming in the other direction at the time) while in CDM. With my Vortech giving me 556RWHP I leave the TC/AH ON. Some day after getting better tires I may try out the CDM on a street launch.

 

With WolfDogs, I would expect CDM to mean "Car Dirty Mode" and understand why he doesn't use it hardly ever...

 

You want to leave AH on at all times for street driving. It's not going to slow you down in any way. I've tried it on and off when racing. When it's off you have to catch it yourself if the tail kicks out which is not easy. I've seen experienced drivers go spinning in circles out of control and you can travel quite a distance before you stop.
