Launch control questions
I watched video's and read what I could. I just need confirmation that I am just being a "scaredy cat"
I failed to use launch control 3x today =/ After evaluating what happened, I feel like I may have just not trusted what I read. I am in a 2016 z51, mag ride, m7.
Procedure- track mode, double tap, select any (I was using sport 1). Clutch in. Romp (not roll) gas pedal. Rpm's stabilize around 4k, smooth clutch release while keeping right foot planted. Does all this sound correct?
What would happen- rpm's would just blast to 6k+
After thinking long and hard about it... how long do you have to keep the gas romp'd before the rpm's stabilize at 4-5kish? When it would reach 6k+ I get nervous and let go. I think this because the car never "banged off the Rev limiter" like my brain is trained to think was about to happen.

Second set of questions. Let's say you are cruising in sport mode. You switch over to track, and then PTM sport one, all while on the move. Then you stop. Will launch control work? What, if any, of these steps must be done with the car at a stand still?

If it is true I need to wait longer for it to stabilize, does no one else find that a little eerie?
First my rpm's shot up with the clutch engaged (rev match) and now you are telling me that when I hold my right foot down there will be a moment that the rom's are falling!?
I really hope you guys pick up the sarcasm in this post. Both things are very easy to get used to and worth it for the performance implications. It is the most beautiful new car I have ever seen that was not a 458. It is every bit as powerful as I imagined, and about 3x more agile. However, it is not quite as pure as I thought it would be.

Track mode, clutch in, select 1st, wheel straight ahead, double tap traction control, hard application of brakes, accelerator to floor, dump clutch.
If you did it right you will get minimum wheels spin. if not it will smoke the tires.

Launch control seems hard on drive-train components, especially if the operator screws up and the engine bumps off the rev limiter. Wonder how many of the cars with blown engines and transmission trouble have used launch control. This is a function I am not comfortable with!

"smooth clutch release"
That's your problem. Just pop the clutch and keep the throttle to the floor.
Maybe this will help - it's an instructor from Spring Mountain showing you how to do it:

I too am afraid of screwing up my car trying launch control. It may be covered by warranty however I don't want to have to put my car in the shop because of this.
Two things I really, really don't understand about launch control. The first is - why not put a message up in the DIC that Launch Control is Set! This way you'll know.
Secondly, exactly why do we need to "punch it to the floor"?!? I mean couldn't it stabilize at 4000 RPM or whatever even with a gradual increase of the gas pedal?!? I mean why is it *required* to stomp it? Seems dumb.

How do you hit the brakes hard and gas at the same time in a m7? Doesn't the clutch need to be depressed? Juan, are you using your third leg down there? Would be might impressive...
I do believe you, because you got it to work and I have not. I just need to know how you hit all 3 pedals?

Thus, quickly press the gas pedal to 100% to enable launch control and hold the engine RPM at the correct speed. This is how the launch control works on my Camaro, anyway.
