A penultimate comment on Giant Firmware experiments...Continued efforts to keep rpm up above about 60 rpm AND get the Auto Assist to work properly continue to be successful. I don't quite have everything down to being 'instinctive' gear changing but, so long as keep my mind on what I am doing, the power increases and decreases are smooth. The lags continue to be absent unless I drop the rpm too low. If anyone has additional observations, they will be appreciated. A question for everyone...did Giant issue an understandable notice of the impact of the firmware changes that I missed along the way? That sure would reduce frustration. Thanks
