I've searched and found the way you're supposed to turn the launch control on is by hitting the TC button 2 times, pushing the clutch pedal to the ground, pushing the gas pedal to the ground which should tap out around 4k on the ls3, dump the clutch and hang on...When this procedure is done, the RPM's just redline.

Is there something I'm missing here?

You should see Competition Mode on your screen when you cycle through the traction control button. That is when it will work. The RPMs should not redline while you're at a stop and floor it while in Comp Mode.

Your front wheels must be perfectly straight or it will not work.

Do not feather the accelerator; put it to the floor quickly.

DillingerRadio

Suspension in "competition mode" as indicated by the DIC, clutch all the way to the floor, gas pedal all the way to the floor (don't feather, don't waste time, just WOT it once the clutch is fully depressed). Once it hits rpm limits dump the clutch and don't let off the gas until it's time to shift.

I haven't had the stones to put the gas to the floor with the clutch in yet (in comp mode). Just goes against everything I ever did racing at the strip back in the day.

This one doesn't have comp mode. It only displays traction control on - off =/ build date is February of '10

Snake.Oiler

Pressing the TC button cycles the mode: traction off / competition mode / traction on

You sure you don't see comp mode?

Wampa

you're prolly not pressing the traction button quick enough...must press twice quickly to see comp driving mode displayed

Actually as I understand it, you don't let off the gas when it is time to shift. You just keep it floored while you shift from 1st to 2nd and the revs will again max out at about 4 grand during the shift. Have I tried it? Hell no. Scares the hell out of me.

I pressed them what I'd consider pretty quickly because it was either in an earlier post on this thread or another that said press quickly. I'll try again tomorrow.

Do these things have flat foot shifting as well? (not having to lift up on the gas pedal between shifts)

Wampa

I have never heard of/tried not lifting pedal for shift. as far as I know/read/experience the launch control's job is done by the time you shift. You should see "Competitive Driving Mode" displayed in DIC if you pressed button appropriate times/quickness

No Lift Shift.
Is it a 2012+ thing?

That was my understanding also, likwise scares the hell out of me too..Someday I'll try it..

Uh no. I tried power shifting for more than a few passes in my heyday of 1/4 mile drag racing, lost time on my ET each and every time. Pointless activity. If you shift quickly enough you should lose 200-500 RPMs tops and stay within the power band...The trick is to hit the clutch a few hundred RPM shy of your desired shift, then let off the gas, clutch in, shift, mash the gas. Anyone who says otherwise can't shift, can't drive, and should have their man card revoked.

All of the aforementioned should happen in less than 1/2 second.

Do you have mild to wild switch for dual mode exhaust? If so that may be the problem. In my 2011 GS with both dual mode exhaust and Mild to Wild switch we discovered that the default mode of Mild to Wild is the "quiet mode" and therefore the quiet mode must be on for Launch Control to be active.

"Professor". The point here is not whether it will improve your 1/4 mile times. The point is that, in fact, the no-lift shift feature does exist when using launch control. If you read through all of the posts that are linked in a couple of the earlier messages, I think the consensus is yes, the feature does exist.

Anyone else find the above to be true?

ProfessorDeath

You're right, I misunderstood the statement that I quoted.

However, consistently power shifting for the sake of power shifting, at least in my experience and some friends of mine as well, we all consistently lost ET. Not to mention it's pretty tough on the engine, trans, and clutch as well if you're banging up against the redline shift after aggressive shift.
