Maximize your launch - Better your 0-60!
I have a 335i with an auto/step with paddles and sport. In everyone's opinion, what configuration is the best way to "launch?" Being relatively new to the performace driving arena, I wanted to get thoughts so I can improve my "light to light" times vs. all the 300C Hemi's out here who like to rev their engines at me.
As of now, this is what I'm doing: 1) Shift over to sport mode 2) Paddle shift down to 'M1' (Tranny will keep you in M2 otherwise) 3) Press DTC button once (This is where a big question mark is, should I turn DSC/DTC completely off instead?) 4) When ready to go, press the throttle as far as possible, hitting that little 'maximum throttle' button when the pedal hits the floor I am fully aware that this probably isn't the best way to get the most out of my starts, which is why I started this thread. Sometimes when I do the above process, the car "dips" when it activates the DTC at low RPMs, and I lose precious power/speed. What do you suggest? If I completely take off the DTC/DSC, should I finesse the pedal a little more so that I don't press it all the way but try to ride that line of the wheels slipping and sticking? Wow, long-winded. Thanks for the suggestions. Brooks |

hold the footbrake, and rev it up to 3000 give or take 500. when the light turns green let go of the brakes and floor it.

Not sure if you can get a good launch in first. But yes, disable DSC and rev the engine while holding with the brake. Shift with the paddles. Do not use the kickdown mode since it drops the gears down, which I do not believe will work in first and second anyway. I think.

And you really do not have to shift into sport mode. Actuating the paddle shifters will automatically set it in manual, temporarily, long enough to street race.

Are you saying it's better to start in second gear?
Yes, actuating the paddles will allow you to drive in manual, but will it allow you to benefit from the "sport mode" without having your shifter to the left? |

Here is how you launch.
I beat a stock z28 at the strip. $100 race. We have a local event here call Real Street Drags. All the streetracers meet up and race at the track instead of the street for a night lol. http://videos.streetfire.net/video/2...6a0116c078.htm |

this may sound dumb, but I have a e90 325, and I like to occasionally rev it up to 2.5k or so with the brakes applied, and launch. Is this hurting anything in my tranny or anything? ( auto transmission.. obv )

That's why you want wheel spin, so your clutch won't burn.

I thought sport mode did faster shifts than non-sport mode?

I am under the same impression as well...I'd like to think a computer can shift faster and better than a human!

Sports mode does not do faster shifts. All it does is shift at a higher RPM than non sport.

holding the brake while applying throttle to raise revs is a bad idea on automatic transmissions, it will cook and fail prematurely. if you really feel the need to "drop the clutch" (i know there's no clutch in autos, but it's a catchy phrase nonetheless) you've got the wrong transmission.
