You always have ABS no matter what mode your in ... The full ABS system cannot be turned off

Here is what these various modes will do for you:

No. Just increases the magnetic attraction between a corvette and ditches.

No it just increases your chances of having a wreck since the active handling system can apply individual wheel brakes to stabilize a car that has gone out of control. Turning off the traction control also won't increase the power but it does limit the wheel spin by throttling back the engine if it senses wheel spin. Turn them both off and you could have an accident looking for a place to happen as many have discovered.

For those of us who grew up driving “Nannyless” cars it puts the whole load of controlling the car on the driver.

Push the button twice and COMPETITIVE DRIVING MODE displays on your instrument cluster. You still have ABS.

Good info as I was told from a guy who worked at GM for a long time that taking it off helps give you more juice!! But Safety wise it does not really seem worth it!!

Well yeah! A local guy was 1/4 mile in the low 16s turned it off and dropped into the 10s.

I guess that 4th mode would be used for drifting.

Yup ... very true

In fact, that is the same guy that filled his tires with hydrogen gas, because hydrogen gas is much lighter than air ....

Since the hydrogen gas is so light, it creates lift, and actually reduced the weight of his car by 150 Lbs. This loss of weight on the tires reduced his 1/4 ET by 3 tenths !

I believe you meant turning ON the traction control...

Hydrogen is a dangerous gas to play around with. Helium should be used as it is an inert gas and not flamable. Although you will not get as much lift with Helium as Hydrogen it will be alot safer to work with.

Changing for all nannies on, to TC off, then comp mode, or all off, does not increase the HP,

But if you look in the different settings under throttle mapping, what happens is as you change from all nannies on, through the steps to all off, it desensitizes the throttle response instead.

To see this with HP tuner, go to electronic throttle, desired throttle area, and look at your A -B -C, XYZ tables.

Also, even if your engine does dyno at a specific number, TM may be holding a lot of power back from reaching the tires instantly instead.
This is the reason that during an after market tune the TM is dehobbled, and it alone of not longer holding back a great deal of instant HP from reaching the tires, is why the car feels so much more powerful from that alone.

So...it does increase horsepower. I knew it!

No, the HP remains the same. It's availability, especially in the low end of the mph range, increases dramatically when TM is turned off.

OK...so does it maybe make the car twice as fast then?? I’m getting slightly overly majorly confused.

NO, your still at 100% with the pedal pushed all the way down, but what changes is the percentage at less the pedal pushed all the way down, which decreases HP the more nanies you turn off with the same amount of pedal push (short of all the way to the floor)..

If we take the AX table, at 59.4% throttle, your at 23 and 84.4%= 65..
in the Cx table, at 59.4% throttle, your at 15 and 84.4% =50
Hence less power per the same amount of pedal push the more nanies are turned off (short of all the way down)

So you still get 100% (minus what every TM is holding back from instant power) with the pedal pushed down, but at less than full pedal to the floor, your getting less TB opening for the same pedal amount of push the more nannies you turn off isntead.

Simply, the pedal to TB opening rate is not linear, and the more nannies you turn off the, less linear the the pedal to TB opening rate becomes; short of the pedal all the way down, which you get all the HP the engine has to offer (short of what TM is holding back as well).

So think this (purple and green), with the more nannies you turn off, the less sensitive the pedal becomes at less than WOT to make the power more manageable coming out of the corners for novice drivers since the nannies are not going to save you instead.

Dano this is all tongue and cheek stuff. Lately we’ve been bombarded by rediculous topics and this can’t possibly be a legit topic.

I use mode 4 about half the time I am driving, otherwise, I am in mode 2, from the diagram.

Once you pile up some miles in these cars, including parking lot burnouts and other "learning" experiences, you find that these cars don't just jump out from under you when you hit the throttle with all nannies off. You can still drive the car fully under control, as long as you don't actually try to create the scenario for disaster (and, are mindful of any wet road conditions).

I bought my CE from a guy my age (68) in TX. He said he had never burned rubber, or turned off the nannies....did not really even know what the button did. From our lengthy conversation before the purchase, I fully believed him. Of course, you can all guess what I did as soon as I was out from his driveway, and he was waving goodbye....
