Hi

Does anybody know what is "Loaded air adaption" i saw with tech 2? In my case it was the first time 2.5% and then 2%

Ladeluftadaptation = Charge air adaption = boost adaption

The adaptions, boost or fuel are not very "long term". In fact, they are adjusted all the time, constantly when you drive in the "adaption windows". The boost adaption is not really power affecting. On steady load, the PID (Proportional-Integral-Derivative control) will take care of any kind of positive or negative adaption on boost. So the power result is not affected. But on transients (short acceleration) you "feel" it: Negative adaption will cause that you never reach the target boost in the short term (it is used to prevent "overshoothing" the request).[/b]

Well ... it is there for a reason

It's just overly-conservative wastegate mapping on the stock ECU ...

It can have a huuuuge influence on power under the right (or perhaps "wrong") circumstances. It just depends on why it's adapting, and in which direction.

Is it better to have a positive or negative value, what kind of tolerance is allowed and after a certain point would we have an error code? (For my car as i wrote it was the first time 2.5% and then 2%)

As far as I know the charge air adaption limit is 100%.
