No, I don't. Thanks for clarification!

 

uh...where did I say that he had 203 miles on his car?....and I said the PLURAL...GENIUSES (kinda hard for two people to have the exact same mileage no?)

 

Wrong. If you have a Z51 with MSRC (mag shocks), you will have PTM. No Z51 or Z51 without MSCR will have Competitive Driving Mode.

 

Damn that's confusing. Okay so page 192 of the manual. OP it seems you may need to be in sport mode. Maybe you didn't push the button twice fast enough?

 

I never said I was a genius but no where in the manual does it say that the car must be beyond 500 miles to use Competitive Drive Mode. Page 162 says to avoid full throttle starts until 500 miles. It does not say that any feature will be unavailable until 500 miles. I'll let everyone know if that was the problem.

 

What’s all this talk about a manual? No manual for C8. DCT only.

 

Found this from an old Autoweek article (suggesting Launch control is available on both MR equipped and non-MR equipped Z51s)

Can someone confirm this?

Here's the link: https://www.autoweek.com/news/sports...supercar-fast/

and here's the important part (discussing the Z51):

"It’s a fairly extensive upgrade over the base car, but we’d bet it’s ultimately a combination of the different final drive and sticky summer performance tires that gives the Z51 that slight edge. Either time is impressive.

To consistently nail those sprints, you’ll want to use the Corvette’s performance-launch feature. Turn it on by switching the car to track mode, then press the traction-control button twice -- the double-press is to ensure that you really meant it -- to enter either Competitive mode (on non-Magnetic Ride Control-equipped cars) or Performance Traction Management (on cars with the fancy suspension).

From there, it’s a fairly standard launch-mode procedure: Depress the brake, then mat the accelerator until the revs build and stabilize at about 3,500 rpm. Then, quickly release the brake pedal and off you go at terrific speed."

 

 

How does that video answer the question? It seems that the ONLY person speaking on this video (instructor) states "PTM" usage. Am I mistaken that PTM is only available on MR C8s? Still looking for a definitive FACT about whether launch control is accessible on non-MR equipped Z51s.

 

ALL C8's have Launch Control. Non-Z51 and Z51 without MSRC have Launch Control in Competitive Mode. Z51 with MSRC have Launch Control in PTM modes.

 

Yes, launch control is available on non-MSRC cars without PTM (both base and Z51), but you enable launch control in a different way as described in several posts above. All C8s have launch control standard.

[Edit: I started writing this while Zymurgy was posting]

 

lol...my launch control consists of holding the brake down, applying boost via RPM up to about 2K and then letting off the brake and pushing the go pedal...2.5 secs 0-60 until the cows come home....4WD is a beautiful thing.

 

My personal opinion is that the launch control on the C8 is one of the better ones. It doesn't require a launch sequence of pressing buttons, etc. once the car is put into PTM. It's always on. Hold the brake and throttle and release the brake, woop. there it is.

 

90% of the people don't read. They "scan" printed material. Most people's attention span is measured in milliseconds.

 

On the C7 it’s a timing thing also. Don’t press the button too fast or slow. Take a video and show us. Because if it’s not there maybe you have a problem with your C8.

 

This is on page 194 of the manual that tells you exactly how to use the launch control.

 

No. in fact I don’t even know where to find it!🤔

 

Friends, Zymurgy is absolutely correct. For those unable to find a copy of the owners manual, here's what you need to know....


LAUNCH CONTROL

Launch Control (Sport and Track Mode Only)
A Launch Control feature is available, within Competitive Driving Mode or PTM, on all vehicles to allow the driver to achieve high levels of vehicle acceleration in a straight line. Launch Control is a form of TCS that manages tire spin, and transmissions clutch, while launching the vehicle. This feature is intended for use during closed course race events where consistent zero to 60 and quarter mile times are desirable.

Launch Control is only available when the following criteria are met:
. Competitive Driving Mode or any of the PTM Modes are selected (if equipped).
. The vehicle is not moving.
. The wheels and steering wheel are pointing straight.

Launching the Vehicle
. Ensure the vehicle is in Competitive Driving Mode or any of the PTM modes.
. The brake pedal must be firmly pressed to the floor, equivalent to a panic brake event.
. While maintaining the brake pedal, the accelerator pedal is rapidly applied to wide open throttle. (If the vehicle rolls due to wide open throttle, release the throttle, press the brake pedal more firmly, and re-apply the accelerator to wide open throttle.)

The Launch Control feature will initially limit engine speed as the driver rapidly applies the accelerator pedal to wide open throttle. Allow the engine rpm’s to stabilize. A smooth, quick release of the
brake pedal, while maintaining the fully pressed accelerator pedal, will manage tire slip and transmissions clutch. After the vehicle is launched, the system continues in Competitive Driving Mode or PTM.
Competitive Driving Mode, PTM, and Launch Control are systems designed for a closed course race track and not intended for use on public roads. The systems are not intended to compensate for lack of driver experience or familiarity with the race track.


COMPETITIVE DRIVING MODE

Competitive Driving Mode allows full engine power while StabiliTrak/ESC helps maintain directional control of the vehicle by selective brake application. In this mode, the TCS is off and Launch Control is available. Adjust your driving style to account for the available engine power. See “Launch Control” later in this section. These lights are on when the vehicle is in the Competitive Driving Mode.

In order to select this optional handling mode, the vehicle mode must be Sport or Track (if equipped with Performance Traction Management (PTM), then Competitive Driving Mode is only available in Sport). Then quickly press g on the center console two times. ESC COMPETITIVE MODE displays in the Driver Information Center (DIC). When g is pressed again, the traction off light i and StabiliTrak/ ESC OFF light g will go out.

 

It took several seconds to get to the 9 and I gave up and then went to the end and deciphered milliseconds in nearly an hour or so.
Pictures are more fun - IKEA Corvette.

 

Zymurgy & jagamajajaran thank you for your answers & help!

LouFarinola, thank you for your post as I was also struggling since the manual is not that clear.

Then there are those of you who feel compelled to post sarcastic & uneducated responses or make stupid assumption about mileage or if one has read he owner’s manual. It’s clear that those with dumb comments don’t have a C8 and probably never even sat in one.
