To add to this, info is definitely there on Legacy S/X if i go into Diagnostic mode but i'm not sure if its not a standard CAN data or SMT just didn't add it in or decoded...

I used to use KWH to Charge Complete 
on my in car display but that signal seems to be broken now in both CanServer and TesLax, don't even see it tracked in SMT. I guess no one is updating the .dbc signal list for Teslas anymore, wish *I* knew how to update it.

I'd post over on this more active thread. Doesn't seem like @amund7 is responding. @JWardell or others there could answer about the .dbc under his github.
Diagnostic Port and Data Access
Summary: updated Oct 2, 2019 This thread is our attempt to acquire and decode performance and other data from the serial networks in the Model 3. We finally gained access, recorded data, and decoded a lot of powertrain CAN data in early 2019. But there's still a lot more unknown! Additional help...

i have a CAN shield that i got for troubleshooting, maybe someday when i have time i'll record some CAN data n see if i can figure out CAC data...

u enter a code in the same field as for service mode.
i got it after i got the car rooted
as far as i know this code is unique to a car n changes over time (well not in my case due to root)

I just need to learn how to use the TesLax app better, I modified the latest 3&Y EVs preset to include the BMS_energyToChargeComplete signal and it worked correctly, so you are right, the TesLax signal list is more up to date.
I hope there is a way to update my previous presets with that signal list. Now I need to explore other signals that have been set to multiplex and complain about them, I think the 12v Amps is one that jumps around too.
Also curious how to get the CANServer to recognize these new signals, I don't see a setting for multiplex like I do in TesLax:

Do you have to UnRoot to take your car in for service? Do you have to avoid updates to keep the car rooted? What's the biggest benefit of having the root done?i got it after i got the car rooted

Theoretically yes, since Tesla's access has been removed after root, which also stops updates. App works just fine tho.
But unless u do it urself, it'll be expensive to root/unroot by someone else all the time (i'm not that smart)
Not a problem for me, i fix it myself n never take it to Tesla.
Main reason for root is to enable CCS/SC. Diagnostic mode came with it which is really nice for troubleshooting.
Keep in mind this was done before CCS was available as retrofit or even adapter itself.. I had to source parts from Korea n Ukraine..
Neither the Salvage HV inspection was available when i did it, although seems it still unavailable for X...
Additionally with root u can get P2D/glovebox codes.

Clarity around CAC imbalances, voltage imbalances, bad bricks, and battery warranty - 2015 90D
I've also had a rapid loss in range for the last months, however I just got the scanmytesla cable and app last week and I don't have much for imbalances. Can some explain the Nominal Full Pack number... Mine reads 62.7 kWh, for my 2015 P90D what should it be? Our 2016 90D reports about 75 kWh...

Didn't work for me, but only tried once... sat in car for 30min and nothing. Will try another day. Going out of town for a while tomorrow.Mystery solved regarding Android and CAC values, thanks to @BrownOuttaSpec

I am a bit confused about these numbers and can't figure out the degradation. Any help? Thanks.

95.4/99.4 gives u 4% degradation but i'm not sure if "full new pack" value SMT uses is correct
best way is to charge to 100% n look at rated value on dash vs advertised rated miles

Yeah, not buying the 4% degradation
TeslaFi shows me 0.71%.
(The drop in the picture is change from 19" to 21" and TeslaFi does not correctly show it or compare to the fleet, it is a "bug".)

Just look at rated mile loss for minimum loss percentage. It’s likely a bit higher than that, but S owners would have to let you know what a typical starting point is for a new pack. Can vary a bit and take a while to dial in.Yeah, not buying the 4% degradation

@AAKEE ’s started around 95kWh estimate but after a while the BMS figured it out and displayed 98kWh (presumably has decreased since then).
So most likely 2-3% which is normal. Will gradually go to 6-10%, depending on many factors, over the next year or two, and then slow down considerably.

Just a comment...it appears @AAKEE and others are correct, the buffer is exactly 4.5% of the NFP, at least for 2023 LR.
I recall it was reported to be much less, 1-3 KwH, at least on the early refresh.
I have 2.25% degradation as reported by Teslafi. Tessie, which I just got recently, says I have 94 KwH usable.
My degradation seems to be normal and right in the middle of the fleet per the above apps.
One day I'm going get the cable and see SMT for myself, like I did with the old 85D
Early S/X had a fixed buffer (fixed in kWh).
Smaller packs had 2.X or so and above 70-75kWh it was 4kWh.
Im sure any S refresh has/had 4.5% since new. Model 3/Y use 4.5% since the intro of these.
Tessie reports the total capacity, until recently they called it ”usable” but I thought it was adjusted to ”capacity” only
Teslafi reports degradation from the first value at joining. For my MSP, which initially showed a nominal full pack of 95.7 kWh, it showed -3% degradation (negative degradation value) as the BMS adjusted to the real capacity.
99.4kWh is the Full Pack When New for the S refresh.
My 2023 is march built, delivered in june and has 9K km.
Nominal Full Pack is around 98kWh (jumping up and down a few 1/10’s).
Todays full charge had 98.2kWh nominal remaining and 97.9 nominal full pack.

Thanks for the info!
Having an older MS before, I was used to the fixed buffer. Switching to percent makes sense.
Tessie does currently report the pack capability as "Capacity".
My car is a May 22 LR with 9.5k miles, 15.3k km.
The current report is 94.2 KwH. Correct for the 4.5% buffer gives 98.4 KwH Nominal Full Pack (NFP)
I added Teslafi on the new car a few months after purchase last year. Never saw more than 406 miles RR. Currently showing 2.25% degradation. The 7 years old car with 100k km was less than 3% degradation.
There are three things missing from Teslafi that make me want to use the other apps
Filtering out the 21" wheel fleet data.

Not sure about this, because not 100% sure what you are referencing…but…
If the report from Tessie says that, it includes the buffer. So 94.2kWh is 90kWh usable, 4.2kWh buffer.
But in the end you can just look at 100% rated range to crosscheck this (the degradation threshold and vehicle constant for Model S 2022 is provided elsewhere here, probably).
