Reason two why it doesn't take a couple of weeks. One, the ECU has no bearing on the time. If it did, other functions of the car would be tied into. Two, define a couple of weeks in terms of distance. A couple of weeks for someone that drives 50 miles one way to work five days a week is very different then someone that only drives it on the weekends when the weather is nice. Three, if the engine started to knock, it would take a couple of weeks for the timing to retard.
The ECU is always "learning' and uses current data to adjust the various parameters.

It depends on what learning you are talking about. I have found that it takes around 4 driving cycles for the idle quality to improve, but it takes many driving cycles for it to tune out the fuel corrections of a V-AFC that has the throttle settings too low or is programmed for narrow throttle fuel corrections.

Just as Gernby said, and there are many topics on this, it takes time for the fuel maps to adjust. That is why resetting the ECU can show noticeable gains on the dyno.
Do a search on it, and you'll find that it can take a while for it to "tune out" the gains of a CAI.

It doesn't take a couple of weeks though. The ECU has an algorithm it uses. It doesn't constantly use old information and then finally accepts it a few weeks later. It can and will use past information to determine if there is a problem. The ECU adapts quicker then you think.
