Launch Control

Sorry if this has already been talked about but I haven't seen any recent discussion on it.

1) How is it done with the ZF auto. Just set it to sport plus, hold the break, rev. to 2k RPM, then let go of the break while smashing the gas pedal till it clicks?
2) Who's actually done it. How many miles did you have on your car when you first did it?
3) If you do it too many times will it void the warranty? Does the car log how many times you utilize launch control?

(Does the car even have enough power to lose traction while launching?)

I'd like to hear your general thoughts on it....

Yeh what u said was right, theres no voiding warranty for that its just made for the tires, it doesnt record how many times u do it

Its just fun

I don't think it's talked about enough. I really want to know if other people have used it.

What is it then? Just a launching trick? The guy in motortrend (ignition ep. 5) did it.

That's a standard Power or Torque Brake launch. Basic Automatic Drag Racing. If it was launch control the car would rev much higher usually to 4k+.

Just read up on it. Launch control is reserved for BMW DCT cars.

Cannot launch with a torque converter. Proper name was break torque launch. Most people had too much wheel spin at 2,000 rpm so they suggested 1,800 rpm.

So I guess I'm asking, what have people's experiences been break launching the car?

Brake torque launch. And it's untrue that it can't be done with a torque converter automatic. Old ZF 6HP's on Audis supported launch control. TCS off, sport mode, hold brake and floor it, release brake when ready.

I doubt the F30 does it and I'm not gonna try it on my own

I'd like to hear your general thoughts on it....
Our cars don't have "launch control". There isn't a program that is designed to maximize traction and acceleration as in cars that have an actual
"launch control".

What we can do is a simply tried and true old method of 'brake torquing' an automatic for a hard and fast launch.
Because our turbo engines provide big torque at low rpm using this technique gives a really nice launch.

Sport+, sport S/D trans mode, hold the brake, give throttle.
Right around 2000rpm release the brake and modulate the throttle. If you go full on WFO on the throttle you may just end up with a smoky launch but not very fast forward progression.
YES, the 335i has more than enough power to smoke the tires even with an AT using this technique.
You'll have to play around with launch rpm and controlling the throttle.
Remember to give decent cool down time so that the torque converter doesn't get over heated.

I've not launched a 328i so I can't comment on it.
But I'll bet there is plenty of torque to break the tires loose.

Perfect, thank you, that's what I was looking for. I'll try it out.

What option do you need to have to get the sport display on the screen? Just interested in knowing what I didn't tick!

Navigation Professional, as you can see from the larger screen than Navigation Business, or standard.

Ta - much appreciated. It's amazing how much more info there's on this forum than chatting to any dealer. I'm not saying the sport display would have swayed me into investing in the Nav Professional but it's good to know!

LOL, sort of a funny thread.

Reminds me the heavy boy-racer slant to these forums. Nothing against any of you boy racers, but please note that a "Launch Control Button" is NOT included in your F30*.

*GI JOE also sold separately.

Yes, No "launch control" on Torque converted cars....you need a Dual Clutch so the computer can slip it on launch. There is something similar to launch control on much more expensive torque converted cars such as lamborghini's but it isn't the same as it is more of an auto-brake stand simulation.

my old GTI had a DSG transmission and that's what we referred to the launch as. I have not tried it with my 335 yet but I think i'm going to try it out today. 3 degrees out, nice and cool

I'll make a video and post it up here later

ummm how would u do a nice launch on the stick? i find if I'm trying to launch hard, soon as i let the clutch out fully the car lags for half a sec cuz the rpms dip. I may be launching at High rpms maybe thats why....its a 335xi if that makes a difference...

launching 6 speed

I had an E46 and this worked great. You may have to add 1 or 2,000 rpms for AWD.

Stop, turn all stability controls completely off (not recommended for safety reasons). Rev to 4,000 rpm, pop clutch.

Wheels will spin, revs will increase to 6,000 and then the car will shoot off like a rocket, leaving a nice strip of rubber.

Did it like 25 times (not in a row) on my e46 with no ill effects.
