No Launch Control on US Models
:confused3
This has been discused so many times since 2005, bottom line: there is no Launch Control on US modelsI was wondering if anyone has knowledge about launch control with SMG, if you could share your experience. Any help is appreciated :1zhelp:

That is not correct. U.S. models have a "crippled" version of launch control. it operates the same way, but at lower RPMs. And the car does not have run flats!This has been discused so many times since 2005, bottom line: there is no Launch Control on US models

Might I suggest reading of of those discussions, 6G Schnell. As andrewsherman said, the US version has a crippled version, which limits the RPMs you're allowed to rev to before lettin her rip.
Procedure: Put the car in DSC off (will not work in MDM mode), S6 mode on the tranny (S6 is not usually displayed on the dash, but will become available when you turn DSC off). Not sure if you have to be in P500, but I can't imagine why you wouldn't be when doing this stunt. So, I'd say put her in P500S. When in D1 at a stop, push the SMG shifter forward and hold it forward. Push the gas pedal down and when you're ready to take off, let the shifter go backwards to the centered position, but be ready to pull back to shift into 2nd gear.
BTW, this has been discussed before, so be sure to use the search function in the future.
One more thing to note is that it's been said that the car keeps track of how many times you've ever used launch control. I can't see BMW ever being able to void a warranty based on too many usages since the car limits RPMs, but it's something to note.
Haha, wow. If you're going to imply someone to search at least know what you're saying first so that misinformation doesn't get distributed.This has been discused so many times since 2005, bottom line: there is no Launch Control on US models

I've said it many times before the M5 launched slower at the track using LC than just rolling into the gas.
Crippled LC
This subject has been beaten to death - owners were talking about starting a class action; Check late 2005/early 2006 postings about the lack of launch Control on US M5.
The simple fact that car does not upshift (a), and revs at much lower RPM (ROW M5s have adjustable RPMs for Launch Control) to me is not the launch control. To burn some tire it's ok, or you could use emergency takeoff instead.

dave and andrewsherman - yes, I read it all......

But it IS launch control and is referred to as such in the manual. That fact that it is not a good launch control and not the same launch control as the ROW, does not change the fact that there is launch control. It uses the same procedure as the system in ROW, it just does not have all the features, hence having earned the name "crippled launch control".
To respond that there is no launch control is misleading and of no infomrative value.
The raisson d'etre of launch control is to provide an optimized launch, i.e., one that is faster than simply pressing/modulating the throttle. If it fails at this core function regardless of what it is called and how superficially similar it is to a real system that does this, then it is still not launch control in any meaningful sense. The simple fact is that following the ROW launch control procedure on a US car results in a launch that is slower than simply pressing the throttle. As a reductio ad absurdum, had BMW labelled the seat heater button "launch control," the car would still not have launch control in any meaningful sense because it fails to perform its core function. In the case of the US M5, the terms "crippled launch control" and "no launch control" are basically synonymous and interchangable.That fact that it is not a good launch control and not the same launch control as the ROW, does not change the fact that there is launch control.

"Crippled LC" is NOT LC

Thank you for a concise summary. Looks like some folks never read posts on LC Class Action and should use the "search function" first, before jumping to the conclusion.The raisson d'etre of launch control is to provide an optimized launch, i.e., one that is faster than simply pressing/modulating the throttle.

Anyone have experience using the launch control on their 2008 M5?
Just so you know, There is no mention in my 2008 manual about launch control.
Being the eternal optimist, I found a thread I think on E60.com where someone said they just got back from S.C. BMW driver training and BMW was demonstrating the launch control and the poster said it was bouncing off of 4,000-rpm (all 2008's). As usual the thread ends there and I can't find where anyone has tried with the 2008.
At a light I put it into S6 and held the stick forward and rev'd the car slightly and the car free rev'd and didn't roll forward! This wasn't the place or the weather to test this so I just let back off the gas and then let the stick back and drove off as normal. There was something going on which got my hopes up.
Weather has been lousy so I wanted to see if it would rev a little higher the second time or above 2,000 (then I planned to not launch again) I tried this and it sounded like it was being limited immediately when I pushed further on the gas (kind of sputtered). I understand that you are supposed to floor it to the point where you engage the kickdown button below the throttle, so maybe that was why as I was just reving it up a little.

Is it still the crippled version or even more crippled?
What is burnout assistance?
Now as a result of this thread I have to ask...
What is "you could use emergency takeoff instead"???
This led me to think they should have just made it so when you are in first you can push forward and engage the clutch and that when you bring the stick back the clutch would disengage or let-out at whatever RPM you rev'd up to. You would have this control in a manual transmission and same worry for abuse on the clutch, etc...

Let me try a short answer:
1. Crippled LC: You did the right sequence, i.e. S6, DSC Off, push and hold the shifter forward and press the gas all the way. Car idles at about 1600 rpm. As soon as you release the shifter car accelerates, will hit the redline quickly and slow down if you don't shift to 2nd on time. Computer will optimize clutch slip vs wheel slip = clutch abuse. Glad you did not try this in bad weather.
2. Emergency takeoff: S6, DSC Off, car in 1st and don't touch the shifter, press the gas quickly and hold (kickdown). Car accelerates, need to shift same as above. No clutch slip and no abuse, but all power goes directly to the wheels = tire abuse. Will burn tires for about 80 yards (while in 1st and 2nd), again only on dry road, no traffic, etc....
Hope this helps.
Thanks for your reply,
I was really just wondering if it is still crippled on the 2008's from anyone who has first hand experience with the 2008.
Guess I'll just try and find out for myself (when it is dry). Although can't imagine wanting to use that feature very much until I get it to the track, maybe...
I have probably done the emergency start without knowing it, although not to the point where I hit the kickdown. Seems like it will break loose with a quick 1/2 tap of the throttle in S6 without doing an 80 yard burnout or does it rev up first when you hit the kickdown. I thought I read that burnout mode will cause the RPM to rise to 3,500 then drop the clutch or maybe that also had to be in D1. Not that I would want to do that or even test that.
Just starting to play around now that it has just recently turned over 3K... I guess I'll just get out and drive it instead of posting question that I can't answer with a simple search, but I can answer with a little time behind the wheel...:blabla

I think I got to stop thinking and reading posts and start driving. Just so much to discover on this car much of which is not covered in the manual...
Thanks to all memebers for any insight you may have and already have provided on so many topics through your posts. This is one of the few forums I have visisted where every thread doesn't turn into a bashing of some sort. Very classy people here...

Well then, by your logic launch control simply does not exist anywhere for the M5 as almost everybody unilaterally agress that it is not the optimum method of "launching" the car -- even in its purer ROW form.The raisson d'etre of launch control is to provide an optimized launch, i.e., one that is faster than simply pressing/modulating the throttle. If it fails at this core function regardless of what it is called and how superficially similar it is to a real system that does this, then it is still not launch control in any meaningful sense. The simple fact is that following the ROW launch control procedure on a US car results in a launch that is slower than simply pressing the throttle.

In the case of the US M5, the terms "crippled launch control" and "no launch control" are basically synonymous and interchangable.
If someone posted a question about the CIA, would you resond, "there is no CIA in the U.S.", based on your belief that they fail at their core function?
The post I responded to was:
"This has been discused so many times since 2005, bottom line: there is no Launch Control on US models"
Kind of amazing that there has been so much discussion on something that does not exist.
You can play with semanitcs all day, but when someone asks about launch control, it is simply uninformative, incomplete and competely unhelpul to respond, "there is no launch control".
Sympathy from across the pond
Have to say that I feel for you guys across the pond.
I've used the LC down a 2 mile runway = wild ride:1: ('08 UK model). Grab the steering wheel in a death grip and hold on baby:sprint00:
Great fun. But I will say that almost as much fun can be had dropping the throttle and modulating to get a quick get-away.

What is the LC Class Action about? Having the US launch control or no launch control? Are you going to join in on the class action?
And instead of folks discussing/hoping/holding their breath for the class action to happen in order "to get euro launch control or simply launch control" , I think it would be easier for folks just to send their M5s to TMS.....
Here's why.....
