My problem was more than a low speed issue. I would pull out from a stop quickly, but not like in a crazy man, and the bike would hit 7K rpm (1st gear) then suddenly drop to 3k rpm and then suddenly race back up to 7k rpm. This all happened within 2 seconds. It would almost throw you off the bike. The first time I took it to the dealer, they could find nothing wrong. *&*&^&^&(*(&*&+^YIUYIT%*& I took it back and told them again how to repeat the problem and then they got it. I had to talk to BMWNA about the safety of the bike. Anyway, I got it back with the new ECU and it was fine.
Since then, I had a PCIII installed and the bike has not had any problems.
