Bear in mind that normally, "smoother" gear changes mean more clutch wear, and "harsher" gear changes mean less clutch wear.

If you want to have smoother shifts:

1) Get the DBW.

2) Follow this procedure:
a) Open the trunk, turn off the battery, wait 10 minutes.​
b) Turn the battery back on, put the key at the MAR position, wait one minute.​
c) Turn the car on, drive very flaccidly.​

Congratulations, every shift you make will feel like an automatic transmission :p

What if?

Following your 2nd recommendation...Instead of driving flacidly, you drove aggressively. Would your car 'learn' the more aggressive driving? In other words, does the 2nd recommendation effectively clear the computer's memory?

Yup. Think of it this way:

A computer is not as smart as a person's foot. When you control the clutch yourself, its much easier... you know exactly what you want to do. You know if you want to drive soft, aggressively, etc.

The TCU has no clue, it guesses based on previous driving patterns (ie, ok, this driver is always flooring it... he must be doing the same thing now!)

Resetting the ECU/TCU gets that done :)
