I've now had the opportunity to ride the new update and put it through its paces. I think it's great. I like that the different aspects of the drive controller are separated and can be controlled individually.
Af first I was apprehensive about the Extended Boost. There's no way to know what the pre-set setting might have been previously, so I just set all the EB sliders to the default. Most of my time is spent in EMTB+, and I found the setting of 8 to be similar to what it was previously. Race Mode set to 10 is fine--it's Race Mode, after all. I rode it this way on some sketchy sections, and it was good. In super-sketch with high consequences, I'd still dial it back to EMTB+.
I'm not sure I could "feel" the pretension throughout the ride. It might be one of those things where you don't notice it until you ride without it. I know it was working because you can hear the motor's ratchet/clutch clicking momentarily when you stop pedaling.
I can't say if there are other improvements, but the bike felt fast and lively today. Mabye it's improved, or maybe the fresh air and sunshine were affecting my impressions.
