The adaptations you refer to are short and long term fuel trims,and transmission algorithm based off of you're driving style. These will change over the life of your car depending on how you drive. some adaptations such as the TCU for an DCT for instance may need to be redone after sufficient parts wear , i.e clutch surface , has taken place. You're car is always attempting to reach a certain target AFR these adaptations are how the car does this in varying climates , temps, driving styles while optimizing the emission status. When you add a significant amount of aftermarket parts , i.e. a new down pipe , the car must relearn how much fuel it needs to add to achieve its target AFR. Thus you initially don't make maximum power. In some older "slow ecu's" like the MS54 it was beneficial to reset adaptations during these times. With an ECU as powerful as in the Siemens in the S63Tu thats just not necessary. It can literally make millions of computations per second and within as little as full tank of gas will adapt to whatever you have thrown at it.
