Unlikely the buffer has changed, but if you have an OBD reader, you can see if the upper end has been capped like many cars, plus you can see many variables affecting performance to a greater degree than Teslafi.

Using the canbus reader, and Scan My Tesla app, confirmed that both battery pumps run at 100% whenever the batt SOC is over 78-80%, and when you have V10.
This even happens at cool temps when driving at slow speeds down hill.

What does this do? Keep warmer batteries cooler and colder batteries warmer during higher SOC? Would it be advantages to set my charge limit to 78% to avoid wear and tear and slightly higher consumption to run the pumps?

When the pump-running-at-80% issue first started, I dropped my daily charge from 80% to 75%.
These days it's 50% and I only have to charge weekly.

Probably evens out the temperatures to improve performance and prevent damage.
I guess could stay below 80% to avoid this running. Might be good to charge to 90% occasionally so the BMS can balance the batteries.

Early on it required charging to 93%+ but for the last few years, from what I understand, balancing happens continuously at all charge levels.

No, I find my car calibrates all the time, and stays in pretty good balance although it has never been to 100% AFAIK.
A long time ago, it was reported the balancing occurs at 93% or above. After many updates and battery capping on some cars, doubt if that is still true.
I store it at 55%, sometimes for weeks. After a while, the range dropped a few miles. The last drive I did, went right back up to 266 RM after I charged to 82%.
I have seen similar behavior with any charge at or above 70%.
Since I got SMT and can see the batt balancing and history of charges, quite happy. Now I wish there was something I could do about the MCU1 besides wait for it to fail under warranty.

I've read different numbers over the years. Latest was 85% on the Model 3 forum.
I think Tesla's recommendation to daily charge to 90% should cover it.

Received firmware 2020.12.5 update on our 2015 Tesla S 85 car yesterday. Release note indicates that now it will now show what stalls are not working in SC and few minor fixes.

But, what did it break? Some newer cars have reported suspension problems.
Most every update requires a MCU1 reboot, perhaps several. Thus can't be good for our ageing MMC chips

I have never done this, and never needed to.
And speak for yourself, mine is just getting broken in

It won't say *which* stalls are unavailable or reduced, only the count of stalls with decreased functionality.

I assume this is speculation rather than official information from Tesla.
