UMC updating to 10amps on 2023.26.7

[JonDarian]

So with better wifi, it has this morning downloaded 2023.38.9.

Not wanting to be bleeding edge (but I do want to get 10A from my UMC)… is that a stable release or the very latest?

I am on 2023.38.6, in the "Advanced" update mode. Hopefully you can get your UMC to update now.

I have June23 MYLR
Bought UMC last week with actual 10A tails
1st use of UMC = 8A. A couple hrs later while still charging during the first charging session it was 10A
Car software still at 2023.38.6

not when they are forced on us.

Meh, what's this got to do with this Thread?

Finally worked!

Resolving my Wifi issues allowed the car to get a car update to 2023.38.9 (was 2023.32.100). Applied the update, then charged the car an additional 1% and left it plugged in once reached limit. Next morning it was 10A.

Thanks all for the advice.

Great! It does feel good to have it working at its full capacity.

Having no luck for my update. Service mode shows error codes meaning that the update is trying, but failing;

GTW_w087_ocuInProgress,
then
GTW_w072_updateFailure

Unfortunately, there is a known characteristic with vehicle software 2023.20 or newer that is causing UMC updates to fail. From what we can see, It appears you're following the correct procedure for updating your UMC.

So seems like there are still issues with the update process for UMC.

UMC update has not worked for me. I'm on 44.30.8.

How did you determine it is a "delivery firmware"?

Delivery firmwares generally have .100 or .200 in the 3rd set of digits (after year.week).

Regular firmware that's rolling out at the moment includes 2024.2.2.1 and 2024.2.3.

Yep same here on my new model Y

MY RWD, delivered Apr 2023.

Having read the above post, I decided to try updating by connecting my MY to my mobile hotspot instead of the home wifi, and it worked! UMC now supports 10A tail as 10A.

Mine MYLR delivered Jun23. UMC purchased Sept 23. 8A initially then 10A after that no issues

You got lucky with the timing of the purchase of the UMC. I bought mine at delivery time in July, but had to wait a few months for a firmware update to update the UMC to 10 amps.

So seems like there are still issues with the update process for UMC.

Following up, seems as if this issue is only for highland vehicles. I might have to plug in and update on an older 3 / MY

Tried this this morning as well, didn't appear to work with my Highland on 2024.2.3 and UMC purchased in Feb 2024.

Did you try the tricks earlier in this thread about charging about 1% higher than your current SoC, then once charged to that, drop your charge limit to a few percent below current charge and leave for a while (overnight)? Also make sure you’ve good wifi connection and have had your first software update.
I had to do the above to get it on MY

I have multiple times, and service mode shows consistent GTW update errors for the UMC. No amount of setting charge levels will fix it.

Yes
Tried various attempts without any luck so far. Will attempt standing on one leg and whistling the tune of 'its a long way to tipperary' next and will report back.

I really don’t think it calls for that sort of violence.
