What is the DCT launch control RPM for the N54?

2000-2500 range and 5000 RPMs

2000-2500 range and 5000 RPMs

What you just wrote doesn't make sense. It's between 2000 and 5000?

You can launch the car between 2000-2500 RPMs based on the preferred method you want to use, or you can launch it at 5k RPM per in the owners manual.

Did this help ?

Yes that helps.

What is the 5k method? That is all I would use, the step won't be able to match it.

Yes that helps.

I believe the 5k is the factory launch control, which just blows the tires off on a tuned n54. Unless someone grows some cojones and puts some slicks on to actually take advantage of it.

When car is at "normal operating temps" and must have more than 1500 (some 1300) miles on the odometer

1. Hold Brake firmly
2. Put car into M1 driving mode
3. One short press of the TC button
4. Press Sport Button on
5. Floor gas peddle quickly

Car will rev to 5k RPMs, and then let go of the brake to launch the car. However, this is not recommended if the car has an aftermarket tune. Its ideal only for the stock tune. You would probably need a major suspension upgrade and DRs. You also have a higher risk of eminently breaking something. There is also no feathering control, only the system TC that uses the rear brakes to regulate traction.

The other LC method is to launch it between 2k - 2.5k RPMs. Any tune will work with this but you will need super sticky DRs and possible suspension upgrade + LSD recommended

1. Hold Brake firmly
2. Put car into MS driving mode
3. Long press the TC button till DCS is turn off
4. Press Sport Button on
5. Floor gas peddle quickly and then immediately release brake

If the brake is held more than 1 second after the gas peddle is floored the launch could fail and or results in over heating the DCT leading to slippage. This is more a rookie method, and will need some serious practice to be able to coordinate the launch and then being able to feather for traction if your on street tires.

Of course all the DCT 335is in the 11s do not use any of these methods. All methods used by those guys are derived from my method of LC

both of you guys need water injection in a bad way. heck running a tiny nozzle with -20 windshield washer fluid would help.

THIS !!!

no one said you need to come out of the hole WOT... modulate the throttle with some Drag Radials and you wont break anything... mash and go is not the way to do things.. of coarse if you stayed WOT outta the whole youll spin but if you modulate youll come out in boost and hard enough to get going and quickly get to 2nd gear and be on your way

I launch at 6200 on drag radials. Go big or go home.

That isn't launch control that's the clutch drop method for a burnout. Launch control will modulate the clutch.

Why are you holding the brake at all? On the M3 you don't it won't engage with it.

True, but you were also making less torque than a sleeping N54. Interested to see how your new setup does now that you are moving some air.

Hence RPM. And more HP. Less stress, more power.

My previous setup was moving air...

@myates

Correct. I have not been brave enough to use LC like it was designed at 5k rpm and limit boost at say 8 psi in 1st and 12 psi in 2nd thru my JB4. Although that might be a hell of an idea
