I just wanted to drop in to say that I discovered a neat quirk in the new firmware:
Up to now it was not possible to set up a mode less than 10/10 support. But with the new firmware it’s possible to set a mode to 0/0. This results in an average output 65W. As far as I can tell this is undocumented and it may be a bug.
This can only be done on the TCU. If you open the app it will show 0/0 on the motor tune graph, but the app will stop you from setting that value directly. If you touch the graph it goes back to 10/10.
I
love this 0/0 mode, it feels really great when group riding with analog bikes. On flat gravel (I know, not the target for the bike) I’m projected to get over 100 miles on a charge, and I weigh north of 240Lb! At 65W, the 840Wh pack should last ~13 hours, if your average speed was just 10mph you can see how the range could get that large.
This also allows you to set up a 0/30 Trail mode for hill climbs. You’ll still have to work hard for it but the bike won’t be a brick.
I really hope that Specialized doesn’t take this away in the next patch.
Other stuff:
Dynamic Micro Tune mode
is documented as giving you 0/100 as the minimum support mode. But the firmware has a bug where the motor shows 0 watts when it’s clearly drawing power. The battery graph goes down but the power graph is 0.
Micro Tune has a 0/0 mode but the table in the
documentation doesn’t have an entry for it. So the motor output for 0/0 isn’t officially defined anywhere.
In the old app/ firmware it was possible to hack lower power levels by configuring a long ride using the “Smart Control” feature to get sub-10 increments of power. But in the latest app they took away the ability to set up rides longer than 100 miles. Now the lowest it will suggest is 10/10.
