Since March of this year we’ve quietly rolled out numerous minute improvements in the V3 Cycle Analyst firmware. Now the latest CA3P13 code includes support for Proportional Regenerative Braking with any Grinfineon or Phaserunner motor controller. Simply squeeze the ebrakes for a base regen and use your throttle to dial it in! Have a read of the cumulative release notes for all the details or see the video below for a quick summary.

There’s no need to upgrade if you are happy with how everything is running. But if you use the auxiliary input potentiometer, torque or PAS control, or have a system that supports proportional regen via a 0.0-0.8V throttle signal, then an update for these new features could be worthwhile.
