85 d here. Have seen 110+ kW once for less than a minute recently. Usually no more than 60W quickly ratchets down to 45, 35 kW. Even in cold weather this didn’t use to be the case. The way I see it, if they want to play this takeback game, they need to give owners an option: with your degraded charge rate, choose to have your battery warranty extended further, or uncap the charge rate and keep the current 8 year unlimited mile battery/drivetrain warranty. In reality, if the charge rate takes 2x as long as what was advertised for the car, this should already trigger the warranty action.

Brought my car in for service. Hoping they can install the latest FW to fix some nuances and quirks. Also, experience very long start ups and black screens when first getting in car.
I just got
“Oh slow supercharging is probably cause of cold weather” LOL. Yes but should be this way when battery is plenty warm and low.
hey, does anyone battery cooling fans kick on anymore during supercharging? I cited that too but service tech just shrugged his shoulder haha

Mine doesn't kick in since they throttled my speeds. I've been calling them daily to see if the updates were available for my car yet and they keep saying no.

So I just got the notification my car is ready.
My car is MCU1 and still on 2020.48.12.
They didn't even check or push 2020.48.30... not sure why. I asked via the msg if they checked the FW. Waiting for reply.
In regards to Supercharging diagnosis "performning normal"

i wouldn't call it throttled since i hit 120 when i'm low, but the damn angle in which it drops is my annoyance. I used to be at 72kW at 50%, now i hit 72kW around like 38% so they have changed the *sugar* out of the curve and it takes forever to charge, i have to add 50% time to whatever the car says, (it says 20 min its actually 30).
My graph is SC speeds since aug 2019, i take the stats at beginning, (when it equalizes for 5 or more seconds at one speed) and right before i unplug.
Dec 2014 P85D 107k miles, 17,900 kWh of Supercharger, and 20,700 kWh AC charge as of 26 Jan 2021.

They are you going to hit you with their standard "Software updates are released to vehicles based on their VINs and their regions. They are not released all at once to ensure that our fleet vehicles can successfully install and implement these updates. You will be getting an update in the near future"
I've gotten this from 4 different reps over the last two weeks

that should be stored on your EMMC chip ( leading 4 digits of a certain filename I believe), so you would need to read the directory of the file system of the EMMC chip board with an appropriate interface ,e.g. a spare MCU connected via Fakra cable to your laptop

So I finally received an update that did increase my sc speeds. I am convinced tesla is trying to fool us though. I am attaching photos of my car charging prior to and after the update. With the new update my new max seems to be around 132kw but the mi/hr is off. You'll see at the same kw speeds the mi/hr are not even close. I feel as though they have us the illusion of our cars charging faster than they really are. The photo with 72kw 254mi/hr is from today on software 2020.48.37 the other is from 2020.48.12 or the one just before it. I aware that one is shown in energy and the other is rated but that shouldn't make a difference right?

Have you changed your display from Rated to Ideal or vice versa? That might throw the "mi/hr" charge rate off but not the kW rate.
I'm not really confident this actually what happened, but it seems in a related area, so maybe. Tesla has sometimes accidentally undone changes in a later update that were fixed or changed in a previous one. For a very long time, the kW versus the mi/hr were not the same type of measurement. The kW was always an instantaneous rate, showing what the power was right then in that second. The mi/hr display was an average over the entire charging session. So you used to have some weird mismatching like that, where the slow ramp up during the first minute or two would make the mi/hr look slow for a while, while the instantaneous was high, etc. Or the car was far into tapering down in a Supercharger session, so kW was low, but the average still looked high. No clue why they used to do that, and it confused a lot of people.
Now supposedly they synced those up about a year(?) ago, so they were both instantaneous measurements, but I wonder if some kind of code rollback intended to address something else accidentally set that portion back to the old method.
So I have the same, built Dec 2014 P85D, with seemingly the exact same nerfed charging curve, and 108k miles. But 40k kw AC, 20k Regen, and only 3k DC, really low fast charging usage, so I have hit 125kw also when really low, for a minute.
So it seems they let the P85Ds keep some upper limits, even though they're the same 85kw packs, whereas other 85s, 90s, etc. got reduced upper limits, especially with higher DC usage, but similar nerfed charging curves, regardless of DC usage.
With the new 2020.48.37 (MCU1), will be interesting to see if the curve has changed at all. Will run the battery down, make sure heat is up in the cells, and see how it goes.

Model/Year/Battery? I have a 2016 90D. 142500 miles and probably 80% supercharged. If I had known then what I know now...
Pretty sure at one time my charging ramped up to about 120kW Somewhere along the line I started reading about reduced charging speeds and wrote it off to unfamiliarity on someone's part about state of charge, temperature, etc ( could have been me
). But as I paid more action I realized that no matter what my initial state of charge or battery temp the car never ramped above 90kW. Someone recently pointed out a bump so today I supercharged after replacing MCU1 with MCU2 and a software update (48.35.5) through the service center.Initial state of charge today: 40%, outside are 88, and battery fully warmed up after a 20mile + plus drive for errands. Surprisingly, the car immediately ramped up to 115kW. I will continue to monitor.
To your point about charging to 84%. Even at 90kW cap on my car it never took that long that I remember. But I also don't charge that high on road trips unless absolutely necessary (and there are few places anymore that I require that much charge).

I'm confused. You joined in 2017 and you have a ton of posts. This situation has happened to me on occasion. Did you not consider trying another spot? It was most likely just that pedestal. Maybe I'm just too impatient buy I would never accept 33kW without moving to a different pedestal (number). Try it if it happens again.

Yes. I have north of 32000kWh of DC fast. 2016 90D. Max had dropped from 120kW to 90kw and stayed that way the last few years until recently. Update 48.12.1 or 48.35.5 appears to have changed that (I did not receive 48.26). I just saw 115kw but have only supercharged once since I heard rumors of faster charging due to some update.
