Firmware v19 for FST bikes has been released to dealers and for OTA update. Since the online FW versions page usually takes a while to update, here are the release notes from our dealer tools:

Code: [Select]

January 26th, 2021
    MY20/MY21 SR/F SR/S
        * Improvements and bugfixes for the SOC algorithm
* Bugfixes for battery capacity calculations
* Improvements for charge rate tapering at high charge rate and at high pack temperatures
* Internal logging bugfixes and improvements
* Cruise control disabled if kickstand is down

    MY17/18/19/20 MBB Rev 32 BMS Rev 39
        * Various bugfixes

[Richard230]

I just installed the BMS Rev 39 onto my 2018 S and it installed within 15 minutes without any issues. However, as usual at the end of the upload you get a message that says that the firmware download failed. All you have to do is to turn the ignition off and then back on and when you check the firmware status again it will show that you are up to date.

From the release notes, this looks promising!! This one should hopefully address all the "Magic charging" issues faced by many and as shown by Brandon and Morgan in their video.
I have also seen very similar issues on my 2018 S and can't wait to try out this update (assuming it's on the fixes are on these bikes too).

From user Alessandro Caruso on Facebook just now:

"I can confirm that on my sr / f after the update made yesterday the bug of the soc is still present."

From a different user on FB
Bela Lukacs Jr
Updated SRF last night to 19 no problem. Have charge set to 95% and it actually stopped at 95 instead of 98%. Also did 80 mile round trip to work today and no ‘magic charge’ anymore. It looks as if it is showing exactly what I use now. Got to work with 61 percent, shut it off, and still 61 % when I fired it back up 8 hours later to head home. Got home with 25% left..... I like it so far

It may take some time for the algorithm to adjust, depending on how they did it. Or maybe it doesn't fix everything... Or something else is wrong with his battery.

[JaimeC]

Thanks for the update.  Updating my "S" as I type this.  Hopefully ElectricCowboy and Morgan Vetter get a chance to really shake it down.

I think that Facebook user Alessandro is reporting an issue that the SoC doesn't correctly report to his phone. Not sure he means the magic charge stuff.

[JaimeC]

Just updated my 2018 S, but with temperatures PLUNGING tonight and bitter cold predicted over the weekend followed by frozen precipitation here next week I'm not sure when I'll get a chance to ride again.  Battery is currently at 50% so it's good for some prolonged inactivity.  With luck temperatures will warm back up into the 30s (that's Fahrenheit for you non-Americans) and the roads will dry up soon...

[Auriga]

I take their release notes to mean nothing notable was released for the non-FST bikes. I could be wrong though

[MVetter]

More specifically there is no firmware update for those bikes as far as I know.

[JaimeC]

MVetter, there was an update for my 2018 S.  MBB=39 and BMS=32.

[Hans2183]

Often when installing the update from the dashboard you don't get notified when it fails. My guess is that those few people now reporting errors just had a failed update. Best to check it with BT convection to your phone then it lists the current and available version. People are way too quick drawing conclusions on FB.

I tried an update today and it seemed to go smoothly.  But when the reboot was complete I got Error Code 8, Firmware Update Failure, and the app still reported version 18 installed.  Also, I've never been able to get the app to show when an update is available.  When I select Manage Firmware from the app's Performance page it searches and searches (spinning wheel) but never shows anything (I've tried for up to 20 minutes at a time).

[Hans2183]

Are you on Android Karl? Mine will also keep spinning on Android never showing a firmware update is available. Same bike, same garage, same network, my iPhone shows the available firmware update. But everytime I attempt installation from the phone it reports an error right away. Updates from bike just seem to install but at the end nothing is updated. So far no luck.

[karlh]

Yes, I'm on Android.  I've discussed the problem with Zero several times, and provided my phone and operating system information, but I've never received a reply as to what is going on or what the fix might be.  This seems to be typical Zero customer support.
