Just for the heck of it, I did a 0-60 in Tour Mode with just launch control. To my surprise 4.00. 2017 A8 Non Z51 with MRC on Michelin Pilot Sports A/S 3+ tires (for winter). This C7 appears to be clearly faster than my 2014.
I wouldn't swear to it, but so far as I know you only need the parameters right (stopped, wheel straight, brake on full, gas on quick, release brake) and it'll work in any mode. It changed year to year, so you really need to check the owner's manual for your particular year.
There's a "special" launch control buried under Track/PTM but I don't know much about it.
According to the 2016 owners manual launch control requires you to either be in competitive driving mode with a non-MRC equipped car or in PTM mode with a MRC equipped vehicle. In either case it is only available with driver mode set to track according to my 2016 manual but maybe it was changed for 2017 to allow access in other modes.

Depends how you read it. I read it as:
Lauch control is only available when the following criteria are met:
- Competitive Driving Mode (Except Z51 and Z06 with MRC)
(Emphasis mine) So I -think- it's available in all modes for the Z06, but not morally certain.

Dave,
You may well be right because as we both know the owner's manual leaves a lot to be desired in terms of clarity. Going from a manual provided by Tektronix to one written by GM is like stepping out of a sauna and landing in the Bering sea. During Heathkit's heyday they would go through a couple of kit builds done by average people and revise the manual based upon these experiences and with the rich feature set of current vehicles the same "typical consumer" based manual revision process would save a lot of headaches and increase owner satisfaction. One of the most difficult things in the world is to efficiently, effectively, and accurately transfer information from the expert to the typical user.

Actually, that delineates the competitive mode (non- MRC equipped cars) from the PTM (MRC equipped cars). Per the manual, you have to be in those modes, which are only available in Track setting, to be able to activate Launch Control.
I was under the impression that you had to be in track mode to engage launch control
Well, in my 2017 I just had the car in tour mode and slammed the brake and floored the accelerator and RPM went to 1600 and the car did not move. I also did not hit the center button twice. The car launched in a very controlled non wheel spin matter. Pulled hard to red line in 1st and 2nd. I was very surprised and best I could do with the proper launch control mode in my 2014 was 4.12 seconds.
You were not in launch control mode, just a hard full throttle start. And you were very happy with it, and should be, which is great. Think of how much happier you'll be when you do get into launch control mode :-)

Clearly your car is an automatic. Now if your car was a manual and you did that, it'd be banging the rev limiter. Not launch control.
Just did it again, same conditions but in track and stabilitrak competitive mode (launch control). 3.80 seconds, I know this is guicker than 2014 could do it.

Were you on a level section of road and are you getting some tire slippage resulting in a measured speed greater than actual?
Level ground and could have slippage, did not feel or hear any. Cosworth Tool Box had it at 3.76. Going to the srip on the 5th and should get some super accurate 1/4 times. Just reporting what my PDR recorded.
