Hi everyone! It was suggested to me to make a post and thread regarding firmware issues where we can hopefully amass information and experiences to find a permanent resolution.
My experiences are as follows:
November 2016 - firmware updated at Hollywood Electrics, LA. No issues
May/June 2017 - recieved letter from Zero corporate suggesting that a firmware update should be considered part of regular maintenance.
August 2017 - firmware updated at Dayton Motorsports, Vancouver. Soc and range estimates become unreliable.
June 8, 2018 - firmware update at Daytona Motorsports, Vancouver. Odometer stops counting. Minor improvements noticed but it looks like underlying issues are still present.
I have not noticed any operational problems. I am told from the logs there are no errors in the battery or any codes generated.
I am also told that Zero cannot roll back to previous versions by tech. I wonder how they will problem solve this ODO problem without being able roll back.vOv
So some of the INFO that matters:
These problems are observed in BMS firmware REV 39+ for 2014-2016
REV 17+ for 2017-2018
I could have reworded this more accurately as , the last stable BMS firmware observed are REV 38 for 2014-2016 and REV 16 for 2017-2018
MBB is unaffected or irrelevant. SOURCE: DIGINOW
Primarily posted to provide information for the community.
Input, experiences, tips or corrections welcome!
Current resolution for myself would be a BMS firmware rollback to REV 38. *I hope*[emoji16]. It is possible ODO is not firmware related... Taking the bike to the dealer in an hour. Will update as more information becomes available.
