Yes, I've been told the same thing about the ECU 'learning' the driver's style of driving. I think its true, because after a year of driving my 147 2.0, other owners have commented that I seem to have a revvier unit.
I guess by pushing it hard, it 'learns' the required throttle respose of the driver. The other owners did not push their cars as hard, so I guess the ECU gives them a more 'relaxed ' response. I'll try to get more feedback from the other owners, and post it for your info.
