Incidentally, we won't provide motor firmware (certainly in the foreseeable future) over the air for a variety of reasons - but TCU firmware will be updateable for most bikes, and that typically improves things like fault detection, bluetooth connectivity, component management etc. Hence Specialized motor firmware uses our own custom-tune and needs to be updated at a retailer. Why? Standard Brose firmware supplied on service motors limited the current demand to the battery in order to preserve range - whereas we've always wanted our riders to be able to use the maximum available torque/power if they chose, with the capability to dial in tuning using Mission Control/support modes. In every case retailers had forgotten to update the bike firmware after the motor replacement, once the bike was fully updated the fun-factor always returned - see Power smashed through the roof - EMTB Forums In case you were still struggling with an issue here Rider - some riders did experience issues with reduced power when they had motors replaced during service.
