Wiki Sudden Loss Of Range With 2019.16.x Software

[faughtz]

TM Spy uses a CAN logging dongle, but I dont have one so not sure how to get a raw CAN log from it

I don’t think it’s fast enough to log everything, are there specific parameters you want captured?

So far, we see the owners of these models are reporting the impact:

S85D
S85
P85D
P85
S70D
S90D

September 2014 AP1 P85+ w/<50k miles - to date dropped from 253 to 222 @ 100%, 227 to 201 @ 90%. Mobile service diagnosed and told me all is fine, asked if I supercharged a lot and say it's normal degradation. Setup an appointment with service center, but suspect I'll get the same response.

 

[faughtz]

Start the app.

Do the setup stuff in the "spanner" menu, if you've not already configured it, to pick a device etc.

Long press the red "record" button at bottom right and pick "raw log"/"can dump".

So the “Recipe Group” does not filter the parameters in the log file placed in Dropbox?

Apologies - was referring to scan my tesla, not tm-spy. Deleted.

That may still be helpful, I have scan my tesla also. Will it capture all can 3 data, at speed?

The limitations are :

Your OBD2 device (elm327 will drop loads of frames, obdlink won't)
The Bluetooth connectivity with your phone (should be fine)
Phone CPU power and io bandwidth.

If the phone is reasonably modern and high-end, and you have an obdlink dongle, you should be OK.

Even if it drops a bunch of frames, if the log is long enough should have what's needed.

It's mind bugling that even after the publication of the electrek article quoting the Tesla's response, the Service Centers are still saying this is "normal"!

Will capture tonight, with battery above 95%, if recent history holds, I can’t get above 97% as the charge terminates.

Well, it kind of is, because Tesla has decided to design it so. Of course it is not acceptable, but it can be “normal”.

85D here reporting no major degradation, still 240 miles at 90% which was the same as it was when checked it around May 31st, 2016 85D pre facelift, 2/16 manufacturer date. 45k miles. 2019.16.2

 

[Chaserr]

If they really clipped off the top it's essentially the same as the software limited 70/75 battery. IIRC it was a $2000 upgrade. One could argue Tesla took $2k value away from the affected cars.

People most affected are posting 63 kwh as the new capacity and the new 3.9v maximum is the old 80% charge voltage, so one could point to their monroney sticker to argue tesla took almost the full $10k 85 package away.

Have you supercharged since 2019.16.2?

wk, uploaded two files to you in a private conversation...

 

[Fleer]

Have you supercharged since 2019.16.2?

Yes multiple times, just did it right before I posted.

edit: attached is a picture of my battery pack sticker info if its helpful at all.

I found this thread which seems to show it as a different revision which maybe is why Im not experiencing it. The other member posting about not experiencing it either was also a 2016 build date so it's probably related.

New 85 kWh battery capacity and 85D Ludicrous

 

[Lukez]

2013 85 here. Been on 16.2 for awhile. On a long road trip right now Supercharging a lot. Supercharged to 96% yesterday for a long leg.

Still have 71.8 kwh total capacity, 67.8 kwh usable via scan my Tesla.
No change since before the updates but I will never allow software updates in the future if this is what they are doing!

 

[sorka]

Is there any reason to think Tesla would not do this intentionally?

Actually, I can think of 691 reasons why they probably did what they did intentionally

 

[sorka]

No one?!

I'm half tempted to throw myself into the pit and get the update just so I can get you data

 

[sorka]

And that there are new algorithms that determine how much is left.

You need to go back there an make it clear to him that the issue isn't one of estimation of range but the fact that it's stopping short of charging the battery to full....whatever the range is.
