Launch control - any risks?

Tomorrow I'm picking up my newly purchased 2012 GT-R. It has just under 20,000km, is newly serviced and fully stock. I was wondering if there are any risks with using the launch control? I know they've improved it over the troubled 2009 version but thought to check here in case there should be any concerns with using it. Thanks for your comments!

Good man! I pick up mine tomorrow as well, don't think I will be sleeping much tonight!

I had a 2011 a few years back and although I didn't launch that much, it's known to not be an issue like it was on the 09 cars.

I'm sure more qualified members will give better info, but if the car thinks it shouldn't do any more it will not let let you, drive a bit and you can go again ***55357;***56846;

Haha, first time I did it I waited till a Sunday and drove out to a big industrial estate, you need a nice quiet big bit if road to pop your cherry!

And don't be afraid to do it in auto! It's super quick gear changing!

Let me know how it goes

Launching it does put a serious amount of stress on the drivetrain and gearbox.. You also need to make sure that your tempratures on trans oil + engine oil are in the safe zones

The stock LC system is very aggressive at 4.5k rpm

I didnt launch mine until i got a stage 1 tune with new gearbox software which allows you to set launch rpm lower and also gives rolling launch which is a lot less stressful on the car

Have done quite a few 3.5k launches now after owning it for a while but 4.5k is too aggressive for me..

At the risk of sounding like a muppet, can you explain what rolling launch is?

lol, it basically allows you to launch the car while moving at a steady rate

You just put it in cruise control, pick what speed, what rpm using shift paddles and then floor it.. Car will build boost then you press cancel and launch !

Ok got it, but what is the advantage of this mode over coasting along being in the correct gear and flooring it? just seems to be adding complication? what would be the real world scenario where this mode is useful ?

Cheers

Well i guess its designed to help with roll racing..

The difference is that when you use rolling launch the car builds boost prior to accelerating.. So when you press that cancel button you get an instant surge of power that you would not experience by just flooring it in the correct gear..

Its like saying whats the difference between launching the car and just WOT from a standstill..

The main advantage is that you can use rolling launch on lower gears at lower speeds and get a similar rush to using the normal launch control except without putting such extreme stress on the gearbox + drivetrain

Ah ok, so basically once the mode is engaged, you have your foot flat on the throttle coasting at the speed selected and the launch is initiated from the "cancel" button.

Yea, you just need to be on cruise control, and floor it, then press cancel to launch.. Although i read somewhere that its not good to hold down accelerate more than 5-10 seconds.. You should just bed the throttle, let it build boost (you can view on the MFD) then shoot

Dont try this in your car though lol.. You need to be running Ecutek V4 that has the feature..
