Hopefully it is still available on the CAN bus. Definitely not going to update now.

sorry i must have missed something, can you explain that last bit in more detail?

I saw that too! I lost 7 kW, even with launch mode. I just thought it was normal variability or aging. I wonder if they also limited launch mode? Can you post your data here?
Power limit with latest software update: Data
The deeper this goes, the more it stinks.
This is with the latest release. My max current used to be about 1620 amps without launch mode. Now it's down to about 1605 using launch mode. Normal aging would increase the battery's internal resistance and lower max power, not max current. Current is programmed via software.

Do you have a P90DL? What version battery? I'll log my max current this weekend to confirm.

Ah, ok. I have the same battery. Can you add your peak kW and amp data to Power limit with latest software update: Data

You can just add amp data. Do you have kW from the canbus as well? It's probably the same, especially if the numbers match up with mine.
I'll confirm this weekend with CANBUS logging.

Max Power for a 0 to 60 run using launch mode:
1606 amps
313.05 volts
502.8 KW
This max power occurred at 46.4 mph.
I used to get a max of about 509-510 KW

What do you get now without launch mode, but with MBR? Is it limited to 1500 amps?

Ugh. Response from my SA:
The data that customer is using is not supported by Tesla and may not be relevant. Customer cannot rely on that data. There was no FW changes that would reduce power. The vehicle log data shows no power output difference between 12/21 and 3/6. Dyno data would have showed no power changes.
Tell them to prove it by showing you the "vehicle log data" that they refer to.

It's nuts because I'm the one that sent them the data and a graph showing the difference. I could do statistics on it, if they want and prove the difference....
I interpreted their statement as discounting your log data, and saying that their log data didn't show a power difference. For instance because it was finer resolution and showed a power peak that your missed (possible?)
So ask them to show you their log data. At least at the service center if they don't want it to get out.
