How many RPMs does it go to?

Any videos?

I would have done launch control out of the dealership parking lot if they hadn't F*cked my order up.

I'm pretty sure that everyone with a 2014 F30 right now, probably just received it recently (within the past week or two) and they haven't made it past their car's "break-in" period as of yet. Give it another couple of weeks or so, then i'm sure the feedback will begin flowing in.

I am with this guy, don't be ****ies with the 2014s. Post videos already

[Bimmerfestool]

Yeah I'm with you too, please do it while I properly break mine in

Provided your engine is at operating temperature, then there is no reason why a full bore launch wouldn't be part of a decent break in for maximum engine power. Look at the routine race engines are put through.

Get the videos up

If it's anything like my M5, you can activate launch control and have the car prepped to launch, and cancel without launching.

So you dont have to launch it really to see how many RPMs it will set to.

The procedure for launch on the ZF is different than the DCT, it doesn't do the hold forward gear selector thing. You essentially brake torque it until it gets to the max RPM allowed for LC and then the flag appears. I found it in the owners manual the other day, as I was trying to launch it similarly to the way my old E92 M3 did, and it didn't work...

You mean the race engines that are rebuilt with every 90hrs of use?

Thanks for the clarification... the M5 LC is somewhat time consuming to set up... looks like they've refined the process then.

Precisely

[Mobster1983]

I imaging it would be different than on the M5/M6. I've never tried it on my M6. There is no track around here and the one time I tried a full launch myself I almost ended up blasting into a light pole. Lol.

I had my E92 M3 for 2 years, and never got to launch it. I know the feature worked, because I followed the sequence just to get the checkered flag, but our roads have too many bends to try that. I did launch my E46 M3 one time on an old airport that is now an industrial park, it gave my friend riding with me whiplash...funny story

I just cleared 1200 miles on my 2014 335i xdrive. Haven't tried it yet. I am happy to finally apply some heavier throttle and use my paddle shifters.

I'll probably use this once or twice to show my friends. My gut feeling is BMW put it in their because the Audi S4 has launch control too.

Wonder if there's a difference 0-60?

If it just brake torques, then no not really as a skilled driver could do that anyway. But I guess the average Joe would be more able to maximise a launch.

Gotta assume there's a difference, otherwise it seems like a pointless feature. If you know how to do it right in a vehicle without laiunch control, there'd prob be no difference. For a guy like me, I think it'd help. But like most, I have nowhere to use it.

I posted a news story in the other thread 2 weeks ago where a blond with no experience and training beat experienced drivers using launch control on a Nissan GT-R.

I bet you could even probably have someone from Florida do it too...

BUMP.

Interesting that on the USA version of Top Gear this week, Tanner Foust used launch control in the McLaren against the other 2 presenters and no one call him "the average joe".

He even pointed out he was doing it because of the difference it made.

FWIW, Adam also used launch control in the Viper during the race. The Lambo did not have launch control.

Launch control makes a big difference on a DCT, which changes how the computer controls clutch slip and what RPM it does this. Pretty sure the Maclaren has a DCT, although not sure what LC does on the presumably 6MT Viper. Edit - after reading up a little on the viper, looks like launch control for a manual transmission is little more than traction control on steroids. It's a whole different animal on an automated manual or torque converter automatic.

I think NISFAN's point is that on a traditional torque converter automatic, it shouldn't really make a difference how the cars launched.

The interesting question is if this new ZF8 automatic does something fancy with the locking clutch on the torque converter. But since brake torquing gives you more than enough torque to spin the wheels, it's unclear exactly how any novel locking clutch control will change things. I suppose proof will be in the actual performance data. Would be nice to at least hear some butt dyno reports...surprised that no one has tried this.

There are plenty of meritless features on every marque.
