@ Gborgan.

Have you heard anything back from Zero? As with yourself and others I have lost about 20% after the firmware update.
Took my ‘15 SR to the dealer a week ago Wednesday for tests. Haven’t heard anything yet.

I have updated firmware on a 2016 S. Had a few days of warmer weather, and got my range back during those days. Hoping your bike will do the same!

I’m in the San Diego area. We have had unseasonably warm weather until the last couple of days when the bike has been in the shop. Temperature would not be the cause of my lowered range.

JamieC —. Any idea what firmware revision you were on?

I found my 2016SR+PT now with v51 to be absolutely horrible. SOC gauge and charging are all off. It was perfect with the previous version 49.  Bike goes to 0% at only 55 miles now, used to be 120+. Sometimes it goes turtle mode while indicating 50%. Battery shows kwhr numbers that make no sense. Should hold 14kwhr, but only takes 9-10 from the wall but indicates it took 12, and I’m pretty sure the charger isn’t over unity. :)  when I talked to the dealer and they talked to Zero, the reason they told me was because I use the Zero supplied QuiQ charger in addition to the onboard and I shouldn’t do that!  Needless to say that I’m pretty upset about this version and the deferral from Zero that this is my fault for using the QuiQ that they sold me.

I’m trying to get in to the dealer again for the third time as I hear there is now a v52 for the 2016.  Otherwise this thing has become nearly useless as I don’t know if it can make the trip to work or not...

Did you get the firmware updated to a newer revision and fix the range issue?  Did you download the zero voltage app to see if the issue is just the range estimation algorithm?

Hi All !

Just got fresh news to tell you about this subject !

I had EXACTLY the same problem as mentionned in the topic !
SR 2016.  8.500 Km. No PT

Updated the firmware (Rev.53) via my Dealer 2 weeks ago.

And immediatly noticed a dramatic deacrease of the range AND of the amount of KW  displayed in the app (8.5 Kwh vs 11.5 / 12 Kwh) . 

The dealer told me a discussed with Zero and they recommend to empty the batery until the bike could not move at all. (I absolutely do not like to do this...)

But I did it this W.End  ( very stressy on highspeed road to see the counter dropping to zero and no exit in the next 4 km... ) . But it was ok, and I even had to make (a lot of)  circles in the neighbourhood tu empty it at all...

After that, I charged it.

At the beginning It was written: full charge in 7h26: Not good, that's the charging time of a 9.6Kwh Pack

6 hours later it was only 40 %

At the end, it was  100% charged in 10H. And the App shows 12,5 KwH

This morning, on ECO Mode, by a rainy day ( usual in Paris for the last 2 months), the estimated range, at the arrival, was 178 km. If  I add the 10 kilometers of my trip, the total rage range is then close to 190 km.

That's mean My lovely bike is Back !! Ah ! Ah ! too happy ! :-)

Hope this could help some of you !
