E53 Launch control
Hello everyone!
I recently bought an E53 and I love the car. Today I was given a GPS performance meter to measure 0-60, 1/4 mile etc.. Since the E53 doesn’t have race start, I floored the brake and gas pedal but what happens is that the RPM go to 2500 and when I remove my foot from the brake the RPM go back to around 2000 before the car launches. Do you have any suggestions on what I am doing wrong because I’ve tried everything, with both ESP on sport and fully off? All test are done in Sport+ with sport suspension. Thanks guys!

Are you saying that the car won’t launch at all? Or are you just experiencing odd behavior with the tach? Any time I’ve launched my 53 from a stop, I haven't had my foot on the break. I’d just come to a stop (on a flat area where I won’t roll), wait for the engine cut, and then floor the pedal. Works fine in both automatic and manual shift modes for me.
That said I’ve definitely noticed what seems like fuel cut from traction control behavior when I’ve come to a stop, kept my foot on the brake, and then tried flooring it out of a corner. It will start to launch and then sometimes lurch, like,it’s detected slip and trying to help me (which isn’t of course helpful). I had the same thing happen in the past with my VW R32 and two gens of Golf Rs, and with them it was definitely fuel cut from (poor) traction control programming IMO.

There's no 4000rpm launches because the E53 doesn't have a MCT. It's a standard TQ converter gearbox, so it'll happily load to 2500ish rpms. Race mode, ESP off, hard on brakes, throttle. let off brakes. You'll know you've "launched" the car when you feel each shift being 2x harder than normal.

With the exception of this answer, it seems most did not read what he wrote.
OP, this is probably normal behavior from the automatic trans since when you let go of the brake, traction drags the engine speed down till the car can actually move. Typical behavior of torque converters.
A TCU and CPC tune could reduce this, since more torque will be allowed at launch to get the wheel speed catching up to the trans speed quicker.
