Interesting. I guess I have to poke around for the dyno data I saw; I thought it was comparative.
One I saw had the horsepower curve for both, but only showed the torque curve for the after.

Have you redone your camera method with the new software (I don’t have it yet)? I’m kind of surprised that your accelerometer data shows higher acceleration basically all the way from 5mph on, since that was not expected. And I thought the dyno plots for the P3D (for what they are worth) also showed differences only above 40mph or so.
Just thought maybe a second time with the camera analysis (which seemed very accurate) might be good to see whether it shows the same acceleration increase.
If you don't have the update yet, YOU should gather a dataset with the accelerometer in your phone to compare. It's certainly more PRECISE than the camera method. The questions are really around its accuracy. It's pretty easy to do...
I'll be interested to see that as well. I am generally ready to believe my data (on my car, as a relative measure), the conditions were as identical as possible (if you look closely at the accelerometer data, you can see the same bumps in my test area in nearly the same places), temperature, SOC, etc. The car DOES feel faster at all speeds. I wish I'd recorded a few more runs before the update, but I wasn't expecting to see something unexpected (the apparent torque bump from 5-40 mph). Oh well. Probably nerding out a bit too much about it...no matter what, this car is FAST and FUN.
Yeah I noticed the identical bumps. Just wondered whether there was some sort of scaling issue or offset issue. I finally just downloaded your spreadsheet, though, and the timing is 100% consistent with the increased torque from 5-40mph (of course...since it's derived from the acceleration as I understand it). You're calculating 160ms improvement though (3.09s 0-60 not including rollout) which is more improvement than I have seen reported elsewhere.
How was the phone mounted? As you're subtracting the initial g-vector from the subsequently measured vectors, I guess I wonder what happens if the phone rotates. In a thought experiment, let's say the phone were completely reversed (so all the "at rest" vectors were reversed from your initial datapoint in the spreadsheet (B3->D3) ) as you slammed the accelerator (obviously this magnitude of shift could not physically happen - but in this thought experiment your method would result in a 2G additional vector added to the vehicle acceleration, wouldn't it?).
So could a slight shift in position from the start of the run maybe could introduce some error in the calculated acceleration vector? I'm not thinking about this carefully or doing diagrams or anything, I'm just wondering.
I'm hopeful your data is correct, to be clear!
We have speculated that they are not updating the site for the AWD.I have the LR AWD non-P....I finally got my 8.5 update yesterday that says I get the 5% increase for power/acceleration. The tesla.com website still shows the 0-60 for an AWD non-P at 4.5 seconds. Does that mean the increase happens after the 60 mph mark or are they just not updating the site numbers like they did for other versions of model 3?

Do you remember their username? I have questions for them.Some amazing individual on a Reddit was able to measure the energy.
Do you know how much lighter the regular rotors are (inside the 18" Aeros used on all other variants of the 3)? I've been wondering how much faster the P3D- would be than the P3D+ as a result of lighter rotors and wheels.

No one has taken it to the 1/4 mlle track yet? I'm waiting for a 11.5x slip!
How hard have you pushed them for heat? I have to figure out what to do about discs, I'm not tracking again with the stock discs after beating them up to the point of needing them turned last time out.
I considered the MPP Big Brake front kit but they require you to run 19" rims, so I'm trying to find another option that'll still stand up to heat better.
Sorry I may have passed on misinformation there. If you have track mode and your original top speed was 155 and now goes to 162. Not sure that that is terribly meaningful frankly certainly the extra horsepower which looks like it's about 20 to 22 horsepower for a long stretch of motor RPM and speed is more meaningfulAre you sure? Why not an increase for the P3D-?
