How bad is launch control - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Those of you with ECUtek tunes and launch control. How often do you use it? I imagine it is very rough on the clutch and other transmission/driveline components.

I know a few F430 variants came with this option and Ferrari would not warranty it and eventually stopped shipping cars with it. Most cars with launch control now have dual clutch trans so this is no longer an issue.

It's meant for racing only, when else would u use it? Ours isn't the same as Ferrari and others because our clutch is human controlled

I would use the feature when I want to. Just curious of the damage it could cause and how people with tunes have been using it, if at all. I don't know a lot, just enough to know it couldn't be used extensively without consequence.

I definitely understand the difference. I chose the F430 because both cars are single clutch and this is something Ferrari did from the factory (at least at first) and I found that intriguing from a production car standpoint.

I have launch control and im very confused about your question. Letting the clutch out at 5,000 rpms is the same whether I have my launch control turned on or not. Its just easier to pick which rpm when using launch control.

ECUTEK launch control doesn't launch the car for you. Its just a rev limiter activated in first gear with the clutch in.

chiefshayan · 07-03-2014, 09:02 PM

Oh it's bad, real bad

Manic · 07-03-2014, 09:07 PM

Well, whether you're driving an automatic or manual, you can imagine what launching at 4k+ revs could do to the clutch. I can't imagine using that feature anywhere other than on a track to be honest.

Dipstik-sportech · 07-03-2014, 09:10 PM

I think you're confusing our launch control with those used in electronically controlled paddle shift transmissions. Whether it be single or dual clutch they work exactly the same. They rev the car up to a preset rpm then bang the clutch in when u release your foot from the brake. Ours is the same except our clutch isn't controlled by a computer so u can release it how u wish. There's also antilag which will confuse you even further lol

Rev to 2200rpm.
Release clutch.

Am I following this the right way? You don't need a stupid limiter to do that.

The question probably shouldn't be "how bad is launch control?" More like, "how much strain does hard launching put on our drivetrain?"

I used launch control today. Every molecule in my body exploded at the speed of light. By body I mean tires.

Any time you drop the clutch at high rpm's it's going to put harsh loads on the drivetrain.

I think WITH launch control though, you can set the limiter to a lower rpm, and more safely, and more consistently ( more important) launch the car.

Yeah that's probably how I should have worded it. Thanks fellas.

mine puts very little strain on my drivetrain since I have zero traction. Launch control seems to be harder on my valve train from overrevving while spinning than from drivetrain shock.

@Reaper, you will never have grip. Leave this world and go to one where the roads are made of glue.

Launch control let's you floor it and build boost and launch at ______ rpm. Can't really do that without.

Traction, however, is another story.

Mine is set to 4000rpm and it will build about 10psi
