Ah - 'adaptive' technology. It's cool, but if you lean on it too heavily as a hardware/software designer, then the system rides shitty until it learns enough to not ride shitty.
So you go get service, it loses the 'adaptive' part and you have a shitty system again until it re-learns. I've had cars like that. "Hey, we updated your transmission's firmware, so it'll shift rough for a little while while it re-learns". That transmission was part of a class-action lawsuit.
Good initial tuning and setup is best. Adaptive learning can be helpful in limited doses and ways.
