MASTER THREAD: 2019.36.1 update released with 5% power increase

[Zcd1]

Sure. 2019.8.4 and up was 7.861 s 0-100 mph. Again, all with 1 ft roll out.

So 7.527 s on the latest software vs. 7.861 s with the previous update, or a 4.2% improvement.

I'll take it!

 

[sduck]

Can you back that up with facts ? Or is that the almighty internet opinion there ?

That's a joke son.

 

[WilliamG]

Now we need to see some quarter mile times!

 

[Ben D]

So, it's a largely an "after 40 mph" 5% bump...

This is only because these cars are becoming traction limited. My guess would be if people did their testing on a sticky drag strip, they would see the +5% from the get go. On normal roads, however, its clear from scan my tesla power data etc. that the software limits power on the initial launch up to around 40-50 mph to maintain traction, only then is the full 400+ kw put down.. The 0-100 mph time difference shows the horsepower increase is real, which means it will also be picked up through a 2-3 mph increase (maybe more) in terminal speed on the quarter mile . Great stuff Tesla and thanks Elon. Now all we need is the promised ludicrous option to dip into the 2.9s for 0-60 and 11.2's-11.3's for the quarter .......

Elon promised Ludicrous mode for Performance model 3's?

 

[MarcG]

Elon promised Ludicrous mode for Performance model 3's?

If a tweet counts as a promise, then yes:

Twitter

My guess is that he’s holding off on releasing Ludicrous for Model 3 until Plaid is released for Model S.

 

[r1200gs4ok]

Did your rated range go up?

no...went down by 7miles

 

[r1200gs4ok]

My range was exactly the same after the update as it was before. Might take a charging cycle to show. I usually charge to 90% and it's anywhere from 279-281. I'll charge tonight and see what it is tomorrow.

thats what I was getting before the update...now down to 277

 

[hmmwv]

The release note never mentioned range increase, correct? If the alleged efficiency gain is true then range increases will be more obvious in highway driving, so maybe someone can do a before and after highway only range test.

Anyone else seeing media related oddities? Connection drops (Spotify hangs up entirely quite often), radio stations unable to change, (and sometimes the stations change but the display does not reflect it), song name display stopped working, etc.

Stability definitely seems to be an issue for me with this release. Even had EAP complaining about blind spot camera issues randomly.

Reboots end the current issue but I’m seeing it happen again after a short while.

I plan on measuring battery power to motor after the update. I just measured it before and am working on refining the data by getting more data points: Model 3 Performance Power vs. Speed per SOC (FW 2019.32.12.2) : teslamotors

Well, from my data, I went from an ET of 7.36 s @ 97.08 mph on 2019.8.4 to an ET of 7.334 s @ 98.78 mph ion 2019.36.1 in the 1/8 mile. I don't have enough runway to do a 1/4. It was 7.513 s @ 95.32 mph before the first power bump (2019.5.15).

If you convert accelerometer data to implied torque and power data using the mass of the car and driver (~1925 kg), the radius of the wheels (~.33 m), and the final drive ratio (9.04, AFAIK), then it looks like I got a boost of ~3.5% peak power, but the area under the curve for power is quite a bit better, which is reflected in the 0-100 and trap speeds at the 1/8 mile mark:

Any LR RWD got this update? What kind of range are you guys seeing ?

Interesting data. Do you have a P3? That looks like a P3 curve (power on the AWD seems to flatline). Torque is the derivative/slope of power and is ultimately the driving force behind acceleration, what's the difference in torque? It looks like 10-15 units.

 

[TestPilot]

Couple of 0-60 runs (only 1 valid) and a 1/4 mile in my SR+ pre-update on 2019.32.12.2.
This was at around 60-65% SoC.

 

[neezer]

0-100 mph went from 8.324 s on 2019.5.15 to 7.527 s on 2019.36.1. That's pretty massive.

WHOA! Can't wait

 

[ChunkAhoy]

Cant wait to see the difference on a SR+

Spotify has been doing that for me since V10 rolled out.

Still waiting on the update out here
