Launch control? Can someone explain?

I am curious as to what launch control is, is it a stock feature or aftermarket... what does it cost and what does it do? I know that numerous 5k dumps at the track with an EVO will force the life of the driveline to be short lived... does launch control prevent this? How does it work? And what cars can it be used on?

Stock my friend. Put your car in 1st at a stop. Clutch in and rev...it will limit at 6,000rpm's. Viola. Launch control.

what he said except its 5000rpm's for stock. when you get tuned it will usually be at 6k.

Except the part about it being in neutral. If it's in neutral.. it will free rev. If however, your clutch is in and you're in first gear.. it will bounce off the two step. Which is nothing more than a secondary rev limiter set lower for more ideal launches. You can still launch poorly and doing so multiple times will still shorten the life of your drivetrain.

Right, if you have a IX then its just that easy. With an VIII you have to get into the ECU to adjust it because it is set too high. You'll hit the engine rev limiter before you hit the launch limiter. Most of the tuners here adjust your launch limiter as part of their most basic tuning packages.

Evo's do not have launch control stock. They do have a launch limiter though. Launch control retards/cuts timing and sometimes adds fuel to hold the RPMs and puts more load on the motor to spool the turbo. Cost all depends on who you go with..... It can cost as much as an AEM EMS. Or you can get a MSD ignition with launch control added on. There is also another company out there that sells a tach and you can add a launch "gizmo" to it for launch control.

The evo's launch limiter is meant to protect the driveline from idiots doing 7K cluch dumps. Its purpose is not for launch control. Ironicly though.... It does produce a good amount of boost. Not as much as true launch control, but it gets the job done for most people. I should also add it is only on 05 and up evo's stock. It can be added to any 03-05 evo via ecuflash.

Launch control can be added to any car. IMO, it would be stupid for some vehicles though.

So it pretty much allows you to spool up before the tree goes green? What is it typically set on for safe launches and good 60's? Is launch control a good investment if you want to see what the car can do at the 1/4? I hear even EVO's have traction issues...

So heres a question... How long does the driveline on an EVO last if your always racing from a dig? I know I've heard that the transfercase isn't the best but that is really all hear say cause I haven't really read up on it.

these are all things that can be researched. i use my two step to launch with, it is set at 5800 and i build about 8-10psi. i cut 1.7x no problem, and 1.6x are pretty easy also. havent made it into the 1.5 yet

2005 was the first year of this. It can be added to 03-04.
