LAUNCH CONTROL PROBLEMS

I'm not sure how one achieves a "bad launch" with the PDK-S gearbox, but that aside, whether using LC gives any benefit or not depends entirely on the layout of the course; for example whether the entry to the starting line or the first turn is a straight shot and/or fairly lengthy or not. Using LC for autocross is definitely a "brainer", IMHO.

Last week I had tuition at the Poresche Experience Centre Silverstone. The Porsche Instructor said to launch you need to
- Press Sport Plus
- Press Brake Hard
- Press Throttle all the way
Slip foot off Brake
Someone said you don t have a sport button, so might this be the problem?

Gentle warm up and cool down is always the key. Much more important than the BS keep it under 4000 RPM break in period. Never seen a race motor getting broken in...
I putter out to the pit lane / to work until oil up to temp and coming off the track, I cruise straight to a fuel station for a few miles before stopping and turning the engine off. Good for everything.

Clubs around here seem to give plenty of lead in room before the timing gear and usually keep the speeds near the start / finish lines slow by having the more technical parts of the course closely associated with the start and finish timing gear positions.

Pretty fast autocross course that let's you get to 75+ mph before lifting for the first turn....sounds like a fun one. I'd try LC in that situation too!

No buttons are required for LC in the GT3. It's available at any time, in any mode, in auto or manual. Hold the brake, floor the throttle, watch for the light in the display, release the brake, go....
Race motors don't have to last for extended miles without a rebuild. But I guess given the way some folks swap cars around here, that doesn't apply anyway.

Moving off with Launch Control
Launch Control allows you to achieve maximum
acceleration from standstill.
Launch Control is designed to be used in a
controlled environment on closed circuit driving
courses where no vehicle cross traffic or
pedestrian traffic is present. Use Launch Control only if conditions permit it
to be applied in a safe manner.
Do not use Launch Control if there is a
possibility it could endanger other persons.
Such a possibility exists if you cannot see that
you have a clear road with no possibility of
cross traffic in your intended direction of
driving.
Information
Stress on components increases dramatically
when starting with maximum acceleration in
comparison with normal driving off.
Preconditions:
– Launch Control should only be used when the
engine has reached operating temperature.
1. Press the brake with your left foot.
2. Quickly press down the accelerator fully and
hold it down.
The engine speed will level off at around
6,500 rpm.
“Launch Control activated” is displayed on
the on-board computer.
3. Release the brake within a few seconds.
Remaining stationary for a long time with LAUNCH
CONTROL can lead to overloading of the
transmission.
To protect the transmission, the engine power is
then reduced and the LAUNCH CONTROL process
is canceled.
In order to drive off, the accelerator must
first be fully released.

Sport button on the GT3 has nothing to do with LC. Mike in CA is correct. I did not have the sport button on. Just don't let up at all on the accelerator as the car will stutter...

Not necessary at all. Brake to the floor, accelerator to the floor. Once the "warning" comes up that launch control is active then let go of the brake and you just go.

Are we sure this isn't a 2014 vs 2015 thing? I have a 15, and I needed the PDK Sport button depressed for LC.
