Hi all,
I'm an SRS french owner since last july. Did you guys have updated your bike with the new 18 version released 2 weeks ago ?
I don't know if it's related, but now I'm getting error code 37 at every charge (CAN communication error), it doesn't seem to induce any problem, I just clear them. Actually, we had also a lot of heavy rainy days at the same time.

I'm currently in the usual SR/F song and dance about getting it to take the new firmware, but there seems to be rumblings on Facebook about it causing issues with the app etc, so i'm in no hurry.
I was hoping by now they'd make this process more durable but alas, not yet. I still have to run my mobile in 24 hour clocks to get around a bug in the zero schedule charging screen, and that was there right at the begining of the Zero next gen application, still not fixed, reported twice. There is also some talk of the application been updated in the next few weeks to fix a handful of issues, so maybe we'll get lucky.
Maybe Zero should add the app code to GitHub so we can fix our own issues and send them pull requests. might speed up the development and bug fixing if they let the community take a look, but i guess that gives away too much commerical info, but a developer can dream right?
-
Zero reminds me of Apple; everything is proprietary. And you're correct about an app update. I talked with Zero customer service earlier today and an updated app is definitely on the way.
-
I can't think of a car or motorcycle company where everything isn't proprietary. Larger companies tend to have fewer issues and you notice it less.
-
Larger companies usually just seem able to hide it better

I have a 2020 SR/S and get Error code 38 after every charge. The bike runs fine, but looking at the red triangle constantly lit is not great. I can clear it, but it returns after the next charge session.
Zero requesting the logs, but for some reason their ap won't work.

I would STRONGLY urge all SR/F and SR/S owners to not update to firmware v18. It will hard cap your range to 50 miles and incite ancillary issues.

Why would such an update exist?

That seems like a heck of a bug.

Someone done fucked up

There's a bit of conflicting information in this thread. gb and trekguy reported error codes when charging, but no performance issues. Then MVetter comes out with a dire warning about a hard range cap. So who's on first?
-
On September 26th the FW update was offered me twice, the next day once, but I declined.
Few days later I accepted the offer but the update did not go through (at least at the end the app (or dashboard?) said it was v17).
Since then I haven't been offered the update anymore.
I wonder if Zero stopped the roll-out of the update.
-
Was this a REAL reduction in range, or were you guys going by the SOC?
The only way to know for sure is to run the bike until it goes dead.
Did anybody do that with the new buggy FW?
Perhaps it was only the info that was off.
I just don't see how it can effect a battery charge. A KWH is still a KWH no mater what is displayed. Motor current draw will also be the same. So the range should be the same as always, no matter what is displayed.

Incorrect. If the bike thinks, for whatever incorrect reason, that it's empty it will stop giving power. Dead. Completely no movement. Turn it off for 20 minutes and it will magically have 30% battery and full power. That is the problem people are seeing right now.

So then the range is the same? Just that you may have to turn the bike off for 20 minutes once or twice because the reporting is incorrect on the first charge?
Regardless, it's a serious bug that needs fixing.

I personally experienced this recently on an SR/F. I started with 55% according to the SoC. I then rode 9.5 miles, and I have pictures/video/map, during which time the bike dropped to 3%. I was stuck at the bottom of a hill the bike would not climb because of the power loss. I pulled off to the side of the road for 20 minutes and it recalculated up to 30% and restored full power. I then rode over the hill which should take 7%; I know that road well and what Zeros take to get over it. Instead I reached the other side with 10% remaining. I then went the rest of the distance home at 45mph, during which the bike dropped to 3% and then wavered and climbed back as high as 7%. While I was on the throttle the whole time. Once home I parked it and let it recalculate, and it ended with over 20%.
edit- you cannot ride on the highway like this. The bike may just decide to cut power. It's a major problem.

Version 18 no longer appears on their website (says 17 is the most current version https://www.zeromotorcycles.com/owner-resources/firmware/ (https://www.zeromotorcycles.com/owner-resources/firmware/)), but I was able to install it via the app yesterday. I was unaware of all the issues before installing the update, and now I'm kinda nervous that I shouldn't have done it! I did go on a pretty long ride yesterday after installing the update with no issues, so my fingers are crossed...

Hiding a failed release is not good form.

That page was never updated with the release notes for rev 18, so it's not like there's a coverup. Zero usually lags about a week updating the website. The current release for FST platform is still rev 18 according to our software.
If you haven't already, the best way to get Zero to do something is to call or email Zero support. Although they won't open until Monday. Logs and detail usually help too
-
To update to 18 or not ? Should I risk what I don’t know. Or wait a bit to see what’s up.
-
I would wait. I see no upside to getting v18 right now.

Yep. there is no gamble in doing nothing.
I even got two bad updates for my Tesla--The fix was wait until the next update. Reloading the same latest update at the dealer didn't help at all. Some updates only have bugs on some vehicles and not others. But you know what you now have.
Just because there is a newer update, it doesn't mean it's better for you.
It's almost like a gamble to get an update when everything is working fine as is.

They updated the firmware versions page format and added v18:

I didn't experience any issue regarding SoC/range behavior with release 18.
Another thing I'm not sure is new: in the app using the starcom api (not connected to the bike in bluetooth), the SoC reports correct value when the bike is charging or turned on. Then after 2 or 3 hours, it drops to 0% until the bike is powered on again.

This is annoying. I really liked being able to double-check the SOC from inside.

At least for the MBB, but not for the BMS. The BMS remains on V. 17 on the website.
My update has been done by the dealer. The app shows me BMS V. 18 now.
-
Update failed for me both on the bike and using my phone. Reading all this I'm glad it did :D. I did see an erratic state of the bike reporting SOC 0 while it really was 74 just after the failed OTA update.
The website was never updated, it's common for this to shows the latest firmware update only months after it being released to the public. This is clearly not a priority for them.
edit: it's not the first bug they introduce. About 2 releases back they had a bug for european users where the bike wouldn't release the charge pistol when you key the bike on.

Mines become self-aware and refuses to take version 18 ;) It gets through all the pre-requisites and starts but then immediatly claims the transfers failed and tells me to turn the bike off. Still on 17.
It's been a while since it's been this difficult to get the firmware to take to the bike. It's usually a few attempts, now i'm up to about eight tries. Might just leave it and get the dealer to do it at some point.
In the modern age, it can't be this hard to tranfer a file from the internet to a device and reboot it.
And i can't check the logs, because now the app crahes when i click on that button. This used to work... sigh... so much for the latest app update fixing bugs.

Interesting!
That was me, the last 3 updates, and this time (18) worked flawlessly.
When it failed before, I just keep trying, day after day and one day it would take it, except for 17, when I gave up the Android and tried with an iPAD and it took the update the first time.
One a related note, I had my charge target set to 95% for many months.
After the upgrade to 18, it is now 70%.
is that Zero's way of telling me it should be set to that value? (Default)
I have not tried to change it back to 95 with the winter just around the corner but was wondering if anybody else had the same experience or mine was a fluke.
Everything else with version 18 appears fine; this is the only difference I can see.

Version 18 was on their webiste, then it disappeared again. I've been running 18 since I posted that and I've had none of the reported SOC issues with the firmware.
-
Since the V18, I noticed, when I store my bike few day, when I turn it on, the SOC dropped a little bite, exemple, 60% to 57% weird.

Last winter I noticed I lost 1-2% SOC a week in storage (SR/F). I had to top the bike off once over the winter to keep it over 45% (I parked it at 60%).
