I did the same thing, few days ago. I figured brake boosting did pretty much the same thing. Man, was I wrong. Launch control is unbelievable.

Can confirm. I did my first launch the day after I had the break-in service done, and first time I launched any car. Holy crap this thing is fast.

Did 3 more for good measure over a 3 hour trip. I think my car's earned some rest for a while

Are you fulfilling all the pre-launch conditions though?
I have done the exact same thing. My M2 setting fulfills all the parameters. Then you just place it in second gear, hold the break floor it and wait for the launch light to come on. What I'm trying to tell you is it doesn't always work. First off once you do it the first time there's some sort of timer I guess for it to be available to you again and from my understanding there's also temperature restrictions on the engine which are probably exceeded all the damn time because I live in Florida. It's 94° where I live. My main questions are after you meet all the parameters i.e. S1, DSC off, 2nd gear and brake hold for launching it what other unknown restrictions can prevent or delay launch control availability? Here are my only two guesses.

1. Timer- A mandatory waiting period between notches? If there is one how long is the timer?
2. Engine temperature restrictions- I believe I read somewhere that there are temperature ranges the transmission and engine must be in before launch control it is able to be activated. If this is true what are they?

Please understand when it comes to me please don't circle back to "you must have these basic settings engaged before launch control could be activated." I know this. It really is quite simple. However I'm telling you that launch control availability has been limited for me having met these basic settings and I'm trying to figure out why. By the way if you hold the break and floor it without launch control activated you lay about 20 to 30 feet of rubber. Ask me how I know.
Couple of things:
- The car needs to be driven a certain amount of time, temps in range etc.
- You should not have to put it in second before engaging launch control, it does that automatically. This could be why it's not working all the time for you.

I was trying to launch for the first time today and got it to go two times out of maybe six attempts. The four times it didn't go my tires just spun when I had the brake in.

Is there any way to check if I'm in D or S for the shifting settings?

Do you have the link?

yea if you are in D drive, there is a giant "D" next to the gear number…

Bumping this. Just tried launch control for the first time tonight on an empty rural road. I almost passed out. Got the total tunnel vision blood rushing out of my head feeling. Is that normal or am I just too sensitive? Honestly it scared the shit out of me. Insane car.

I’m just glad it worked for you. It’s a crapshoot whether it actually launches or not. Sounds like it worked well for you on your first try.

It’s been discussed a lot. And I am just repeating what I read and XHP claims. The claim is that ZF8 limited to 50 super hard luanches. After that supposedly it won’t shift as hard even though LC is active. I have no proof of any of this but if you search the topic it’s discussed a lot.

I’d bet I’m north of 100 by now. I have 79 saved in dragy, many others not recorded or deleted. Still hauling ass. Wheelspin is the bigger problem

It’s the tires. I have times earlier than these that were slower in the 3’s. Roll of the dice whether it hooks or not these days. Been waiting for my new wheels since March to put the Nittos on, now Apex is saying late June will be happy to make you a nice little clip when the day finally comes

Roger. Again I don’t claim to know about exactly how many u get. I was just replying to the person who seemed to never heard about any of that.
I sure hope it’s more then 50 now!!!

OK man how are you getting in the high 2’s???? Tuned?

Second question. Does launch control work 100% of the time you try it? Mine doesn’t. It’s been explained to me if certain temperature parameters aren’t met it won’t launch. Of course no one can tell me what those parameters are.

Yes and yes, DME tuned but not XHP. Haven’t had any issues with LC engaging, I have all the settings on M2 so it’s just double-tap and go

Could be about right. The car really hesitates when simply slamming on gas from standstill, and doesn't really launch at all.
