Agreed... so far most of the riders are having problems after the update... no need to do it. Thanks.

Can you undo an update? if it is... might be worth it.. to have it working the way it was before the update.

Hi,

First of all, thanks for this forum : Plenty of usefull informations here. That's great !

I searched for informations on this thread (and others), and I'm still not sure how to charge correctly my zero sr 2015 (stock firmware)... The informations are cristal clear for long term storage  but I'm not certain that pluging the charger every day (i use 5-10 % a day) is good for the battery. Maybe I missed something, what would be you advice ? (I send a message to zero a few days ago, but no answer yet...)

Thank you !

I leave my Zero plugged it until it is fully charged and the batteries have balanced (indicated by a steady green charging light) then pull the plug. I ride my Zero several times a week.

My '16 SR is back to having rock solid SoC and range estimates after firmware downgrade/revert. Electric Cowboy has more info about this process.

Hi All, new to the forum and fairly new owner of a 14 Zero SR. I got it for what seemed like a steal from a dealer (non zero). When i received it was 100% charged however every time i have charged it since it constantly stops charging anywhere from 89% to 94%. I plan on taking it to a Zero dealer soon (need state inspection done anyway) and was hoping the firmware update the app keeps reminding me about may help.

Anyone else have this issue?

Overall it does not affect me much. I still get to work with about 65% left with mixed highway and backroad riding.

Here's something you can try if you want it fully charged: If it is stuck around 90% remove the cord from the outlet and after some time(half an hour, 4 cups of coffee, something like that?) plug it back in. It should kickstart the charging to 100%.

[phillypilot]

Thanks! Since i charge at work I'll go unplug before lunch then plug it back after lunch to give that a try.

Updated firmware in June 2018. 
No issues with update.  Two years old and still best bike I have ever owned.
 

Updated July

after update odometer frozen at last firmware update.  everyday range gets worse.  Uses 40% more battery charge to do same trip as before.  I didn't notice this right away but after a few rides noticed it was worse after update.

Update end of July 2018 again:
Dealer had wrong type of motorcycle selected in firmware update.  Fixed the update and now bike is better than ever.  Total cost was two trips to the dealer to fix it.   Lesson learned for me was make sure that your odometer works before you leave the dealer after the update.

Still love this bike.

Unpinning this topic of new charging recommendations, seems the information is well-known by now.

thank for information

I finally decided to update the firmware on my 2016 DSR, I was hesitant for a while... a lot of members were/are having issues after the update... but rolled the dice and did it. The good news.. it feels the same... it was working great IMO before... so for me no change is good... but with a newer version... I think is 53 now.

I download the logs to confirm the update, before and after the dealer update. I had 40 now 53.

What is the other thing that I need to check if it was updated? BMS?

Thanks.

And what a spectacular firmware update failure it was for my 2014 DS, completely trashed the bike as reported under separate thread! Embarrassing for Aaron cheatham, I wonder if he still works there!?

[Richard230]

My old 2014 S is still running fine with the original firmware installed by the factory in early 2014.  The estimated battery power percentage is particularly stable and will run right down to 0% before shutting off (no hidden reserve).  I think many of these firmware updates by Zero are an attempt to increase the operating life of their battery pack and sometimes they just don't work out as they expected.
