@ days ago after 1750 miles I swapped in a new bosch performance line cx motor in my bike( yes, I scored a new motor) and I was happy to discover it fired right up BUT it does not seem to have any noticable power when you start pedaling at first but hen works perfect. I also have a chip in my motor from epic to allow it to go over 20 mph. What i want to know is can I do a firmware update on this motor myself somehow without goingto a dealer? i dont like dealing with dealers. thanks
