I think the PTM (Performance Traction Management) with it's different track modes are not available on the base car. It is mated to the Mag Ride, which is available only on Z51, if memory serves.
Without first hand knowledge, the 2014 Corvette brochure says launch control is available in track mode (which all Corvettes have the track mode available with the 5 mode selector).
They all have the same 5 driving modes. The differences are based on Z51 or not and on what options you do/don't have. In the chart below, the Trans Shift Mode only applies to the automatic tranny, the exhaust mode (other than Eco) only applies if you have the NPP Performance Exhaust, Electronic Limited Slip Differential is only on the Z51, Magnetic Selective Ride Control and Performance Traction Management only apply to Z51 with MSRC.
For an automatic, do I hold the brake and press throttle until about 4500-5000 rpm then let off the brake for the launch control? Thanks in advance for the advice.

No, you put the throttle to the floor (page 9-45 of the Owners Manual):
Automatic Transmissions
. The brake pedal must be firmly
pressed to the floor, equivalent
to a panic brake event.
. 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 to stabilize.
A smooth, quick release of the
brake pedal, while maintaining the
fully pressed accelerator pedal, will
manage wheel slip.
The important thing is to let the RPM stabilize. There is no exact RPM number. Snap your foot off the break. Do not slowly relates the break. The computer is looking for a quick release. Same with a clutch operated car. If you try and slip the clutch launch control will not work. The computer sees the quick release of the clutch.
1. Stabilize the RPM
Pop your foot off the break or clutch pedal depending on standard shift or automatic. I had a talk with a certified C7 Corvette tech. He was adamant about the break or clutch operation ...

Honestly that looked like a terrible launch. Very slow. The system needs to allow a minor amount of wheelspin (minor) and it will be much faster than that. This is why guys are able to launch much faster without this system.

I was actually just noticing that after a rematch.
Ok I tried this tonight and something didn't work?
In track Mode:
Pressed traction control button twice, turning off everything?
Put it in Drive.
Stood on the Brake.
Quickly Floored the gas and it about dies?
Lett off the brake, it bogs and then takes off?
Tried again, this time in Manual Mode 1st gear.
Stood on Brake.
Floored it and it about dies again?
Quickly release the brake and it bogs slightly and then takes off?
Any ideas?
This is a non Z51 2LT automatic, does that matter?

what rpm is it at when you feel like it about dies? 0-500 would be close to dying. running rough at 4000 means it is working properly.
No. It revs up to where the computer thinks it would be appropriate to launch. You have to let it stay at that higher RPM a second or two before you activate. Let go of the brake or pop the clutch..
I have the same issue.
As I attempt the launch, the car doesn't rev up.
Instead it stays low, almost to a point where it will stall out.
I have a 3lt Automatic without the Z51 pkg.
I am in track mode and then I put it in competitive driving mode. Hold the brake down all the way and stop on the gas
