Made 12 half mile passes at an air strip. Down right disgustingly humid with tarmac temps reaching 119 degrees. Smacked almost everyone off the line, ran consistent 4-4.5 0-60 every run using the just above 2,500 launch method. Less humidity and cooler temps result in sub 4 runs.
(Forgot the AC on during several runs)

Tried to use it several times without any luck so gave up on it. And yes, I read the manual and 2atched several videos still could not get the dang thing to work. Whoever programmed and approved this function should have been fired. It could have been executed in one step, with a simple press of a button.

Tried mine today on my 2016 Z06. worked perfect. launched straight with little or no tire spin. I left it in auto and it shifted lightning fast. i was worried about losing control but that was not the case.

My track has poor prep on test and tune nights so I use it all the time , I get consistant 1.8 60 ft times on stock run flats with my LT1 A8 and this was with DA over 3,000 . Cant wait to see what it does in good air
Tried many times to launch without it, walking the gas pedal to the floor and pedaling it etc , just ended up blowing the tires off of it .

As many have stated & it is true, the gas pedal must stay fully to the floor or the car exits Launch Control Mode. So if you're going for 0-60 mph your tranny (A8 versus M7) may have to shift once. If going for higher, say 1/4 mile perform the NLS ( it is AWESOME!). But be warned if you NLS a Z06 & are not careful (have a poor alignment or not going dead straight) you can end up in the weeds or worse immediately. All of us C7s need to be careful doing the Launch or NLS if outside temps are below "normal" for High Performance Summer Tires. Quite the paradox, the OE tires are soft to get great traction, but become HARD & loose grip below "normal" temps. YEE-HI! & good luck!
I need to watch that video!

You have to follow Launch Control procedures. Regardless of tranny, when using Launch Control, the pedal is fully depressed & HELD DOWN. The RPM will stabilize at certain RPM (slightly different between A8/M7). If it goes above 4K you are NOT IN LAUNCH CONTROL. With the A8 & brake held FIRMLY to prevent movement, simply release brake when RPM is stable & enjoy the ride! With the M7 ('16 Z/M7 is mine), the same applies except hold clutch fully down till RPM stabilizes, then QUICKLY release (it really is dumping it), holding gas pedal to floor w/o letting it up till you are thru accelerating to desired speed which means doing a NLS (no lifting of gas during shift). Regardless of tranny, the gas MUST be all the way to floor or you aren't in Launch Control. I've done many of these in my car & learned on my '09 Nissan 370Z which was an absolute HOOT & no fear of losing control with ONLY 332-350 HP. Side note, I bought it because it was first I had heard of REV match transmission & man could you throw that thing thru the corners! You should watch videos from Spring Mountain or other EXPERTS & not RELY on anyone else (YouTube idiots), or including me! Look in the ask TADGE threads where he explains how to set up for using launch control, it is very good also. PS: When you ask for help here, play nice & try to ignore the few smart asses (you'll learn who they are in a short time of reading posts).
Thanks for the info.
PS..I've been a member for 12 years through 3 vette generations. And yes, you do learn who the smart asses are.
