: SST Launch Control
UnctrldRage 02-14-2008, 12:58 AM Hey I was at school yesterday in the library on my break reading Road & Track issue with the EVO X vs STi While the article itself was a familiar read to me the little sidebar that was not including in the online one I read stated how-to use the SST's Launch control.
Here is how its done
Put Transmission in S-Sport Mode
Turn of the Active Stability Control
Hold brake Rev to 5200
Launch Evo X MR.
If I can find and take a photo of that sidebar I'll post it on here. Unless someone can find it online.. I knew how much we were speculating on launching the SST so there it is
MEVOX 02-14-2008, 01:12 AM Here is how its done

Turn of the Active Stability Control
Hold brake Rev to 5200
And break all 4 axles at once.:-D
UnctrldRage 02-14-2008, 01:58 AM I thought that the same thing but that is what it said no lie.
saturn 02-14-2008, 02:54 AM I don't see why this is so unbelievable. The DSG on the Audi's work almost exactly the same way. Now, the first incarnations of the DSG to the US didn't have launch control, but later on they did. I've seen some videos of the DSG's in drag races and they really do make a difference.
UnctrldRage 02-14-2008, 02:59 AM I dont know what RPM The DSG launchs at....I do know the Lamborghini Gallardo launches at 4000RPMs...so another 1200rpms seems a bit much Especially with the way they say the TC-SST cant take more power mods so do you get where the assumption is that 5.2K rpms could break the axels...well atleast maybe an ACD or AYC unit....
turbo99jetta 02-14-2008, 05:32 AM <~ has a GLI with lanch control. 3000 RPM to answer that question. and still yet talk about wheel spin and hop...
Robotix Junior 02-14-2008, 09:30 AM lol, don't trust everything u read in mags dude, however, a 5200rpm launch shouldn't cause any problems, seeing as how the X has a rigid chassis!
saturn 02-14-2008, 04:58 PM <~ has a GLI with lanch control. 3000 RPM to answer that question. and still yet talk about wheel spin and hop...
GLI != Evo. The suspension, tires, differentials, etc are all completely different.
Several magazines have talked about how they launch the STi at 6k+ to get the 1/4 mi and 0-60 times they do. While 5200 may be high, it's definitely not outside the bounds of possibility.
my 06 gti(apr stage 2 93) has launch control it caps at 3200rpm but i grip nothing if i launch over 2500 but it doesnt matter cause its at full boost already so its gone.
DirectorSe7en 02-15-2008, 07:00 AM And break all 4 axles at once.:-D
LMAO! I wont be trying this either.
No thanks...

You know I just caught this goof...Dont cars only really have 2 (TWO) Axles not 4....
Robotix Junior 02-15-2008, 08:19 AM Oh yeah! Damn, and there's me thinking my car was built wrong! lol
Guys that is why it is called the "launch control." The computers control the amount of torque going to the wheels so as to not damage the SST.
You could still launch the SST without any computer aids but that would damage the tranny in the long run. This way it's foolproof.
There is a secret launch mode where you don't brake launch and more torque is used. This is the fastest launch for the X, and I don't remember how it's done.
Robotix Junior 02-15-2008, 04:15 PM Surely if you are quick enough, you can launch without computer aid and without damage to the trans?

lol no the computer will not allow you to dmg the trans it has complete control over when it shifts and how much torque it gets
in my gti if i just mash on the gas from a stop i sit there and spin out until i get traction.
if i slowly give it gas and then mash on it sometimes it spins sometimes it goes but always there is wheel hop and traction control trying to compensate unless its off then i just spin my tires
if i turn off traction control put the car in S and hold the brake and give it gas til im about 2500 rpm i can slowly let off the brake while still giving it gas and the car is gone
Robotix Junior 02-22-2008, 01:06 PM Fair point, but we can only assume the X is built the same, it might be a new design process. Just gotta wait till i can get my hands on 1
ethanhunt 03-06-2010, 01:41 AM So any ideas how the secret launch control is done?
crimson49er 03-06-2010, 01:47 AM S-Sport Mode
ASC set to off-off
Hold brake, gas peddle to the floor (it will only go to about 5G's)
release brake

That means i've been using the secret launch control all this while. All this while i thought this was how you normally use the launch control. Because pressing the ASC once doesn't really off the ASC.
NomadicMarine 03-06-2010, 02:09 AM So the difference between the two launches has to do with hitting the ASC once or twice? Am I reading this right? What's the difference?

gunzo 03-06-2010, 02:57 AM He is not totally correct .. You can totally turn off ASC ..
He's probably confused between all the A's on the car .. AYC .. ASC .. ACD
You can NEVER turn off ACD / AYC
ACD controls front rear splits .. normally in 50/50 configuration proportioned to as little as 100/0 front rear ..
AYC controls the rear wheelspeeds .. in a way .. it is an electronic LSD .. torque split can be as high as 80/20 to the grippier corner ..
ASC controls the brakes and the throttle to prevent loss of controls
with 1 press .. you disconnect the throttle portion but the brakes still work to attempt to keep th wheels in line ..
with Press and Hold .. you disconnect both the throttle and brakes so that there is NO MORE LIMITATIONS on the car .. you CAN PUT THE CAR OUT OF CONTROL..
All this info can be found on the Evo X development white paper
Tephra 03-06-2010, 09:07 AM ASC still doesn't save you if you enter a corner too fast :)
chindian 03-07-2010, 10:40 PM LMAO! I wont be trying this either.
No thanks...
You could never break any axle, the launch control is just a slow engagement of the the clutch on an SST trans @ 5200rpm
VampireSix 03-08-2010, 01:05 AM I tried doing the launch control today. Stop, car in manual, super-sport mode, hold down ASC until it beeps (off-off?). Left foot on the brake, and as soon as I start to press the gas I can feel the car trying to move forward.
I got the "Slow-Down" message before I could rev to 5k RPMs.
I thought this was the correct procedure?
bradze 03-08-2010, 01:14 AM im afraid to ever launch it again now that i have more power, but the way i always did it was hold the ASC til the arrow appears, transmission in s-sport, rev it up and let go of brake.
steelbahamut 03-08-2010, 01:20 AM On my recent tuning escapades we have limited 1st gear boost to like 17psi, apparently as long as you limit 1st gear boost to around that you can launch it as much as you want, within reason. No issues launching mine w the Green sofar.
VampireSix 03-08-2010, 01:25 AM I just saw some youtube videos about SST launch control, and it looks like they were all done in Drive, not manual. Is drive mode, not manual, necessary for launch control to work?
Yxd68 03-08-2010, 01:38 AM Is drive mode, not manual, necessary for launch control to work? No. works same in Manual but you will need to make the 1-2 shift.
gunzo 03-08-2010, 03:38 AM you can't 'ease' the throttle in :p
stomp the brakes and stomp the throttle
you creep or you ease in the throttle .. it'll say slowdown
kajida 03-08-2010, 11:23 PM Mine only allows me to rev to 3,000 and then I get the slow down message...you have to be quick or it'll go into limp mode...with that said, don't sit there holding it forever or the same thing will happen

Eeek, thats bad! Did that twice myself too before I learned my lesson :duh:
HARD brake and SLAM the throttle. If you alice it, it burns up clutch. Sort of counter-intuitive.
Spoonie 03-10-2010, 04:32 PM After reading some of the replies here you would think that you would destroy your engine the first time you did it. Some of the replies here are unfounded and just plain retarded. I've used Lauch control plenty of times without issue. Glad I didn't read this thread here and mis-inform myself.

+1 I have used it will no ill effects...
