Thanks. I checked that thread and any others I could find. My car has the console, so access to the connector should be behind the hockey stick shaped trim panel on the passenger side. I can't see it, so I just wondered if anyone else has been able to locate it.

You're talking about this thread maybe with Front/Rear Torque numbers vs Total Power...one of these graphs even includes Rear RPM/Rear Torque!

The CAN bus connectors are behind the cubby (center dash). Older are white while newer are blueish colored.
If you don't have a console that's true. With a console in place you can't lower the cubby enough to get your hand above it to grab the cable.
The fix for that was routing the cable over to the passenger foot well, and you gained access by removing the hockey stick shaped trim panel along the side of the console. I've removed that trim, but the cable is not there. Thanks for responding though.
I'm in the process now of removing more trim to see if I can locate the blue connector.

Found it. After removing the passenger side dash trim, I could see the blue connector sitting on top of the cubby. Hmm. They've changed the way the cubby is installed on newer cars. The older cubby had four metal spring clips, two at the front and two at the rear. To gain access you would release only the front spring clips and let the front of the cubby swing down to expose the cable. If you inadvertently released the back clips, it was difficult to get the cubby back in place. On the new cars the cubby has clips only at the front, and there are two tabs at the rear that fit into slots. After pulling the front of the cubby down to release the front clips, it slides out completely toward the rear of the car, exposing the cable.
The new front clips are much harder to release than the older ones. I thought I was going to break something.

TM-spy can bus analyzer:
July 2016 P90DL in ludicrous, max battery ready at 112 degrees, 94% soc.
Max power at 1615.4 amps, 310.2 volts, 501.1kw, 672 hp

Obviously, everyone is at TMC + Gigafactory event as no one is commenting...
We've been waiting for so long for this number!!!
1600A at the battery!!!!!!!!!!...with significant less voltage sag.
When I pull 1500A, the voltage of my P85DL drops to 294V.
So this is not 'only' new chemistry and reduced voltage sag, they are allowing an extra 100A to go through that programmable fuse!! :-D

I think you're on the right track but I'll bet it's closer to 1600 amps
Finally some real confirmation. Very nice Tippy!!!
Anyone care to start a pool on P100D battery current
That's 441KW which is a bit lower than a P85DL at 90% with max battery ready (305 volts).
At 1490 amps, the battery is at 322.5 volts. That's the closest sample I have to 1500 amps.
305 x 90 / 85 = 322.9
1500 x 90 / 85 = 1588, so they're not pushing it that much harder.

P100D:
1600 x 100 / 90 = 1777, so maybe they'll push it to 1800.
Looks like the higher capacity batteries more or less maintain the same voltage but at higher current,maybe a little more.
Lets call it 315 volts at 1800 amps, so 567 Kw or 760 hp. Hmm, that's pretty close to the combined hp of the two motors, before conversion losses. Do they quote power at the output shaft?

The thing is, that power and capacity stand in no correlation, when it comes to batteries. Tesla could come up with a 150kWh pack that can only supply 300kW, or with a 95kWh pack, that has 1MW. Both unlikely, but possible. To just assume, that a 100kWh pack has 11.11% more power, is as valid as assuming that it has 11.11% less power.

If you were comparing apples and oranges, I would agree there would be no (guaranteed) correlation. However, when dealing with the same or similar chemistry and construction, it is not unreasonable to see an increase in power sourcing accompany an increase in capacity.

Tesla, not TSLA!
Has tesla ever reconfigured the pack for the Model S? I remember in the past that the smaller packs had blanks in place to drop the capacity to whatever they were selling.
If they don't reconfigure the pack then logically they would have to change the battery chemistry.

All of tesla's packs to date have increased in power with increased capacity. And in going from 85kwh to 90kwh the increased current ratio was pretty close to the increase in capacity ratio.
The 85kwh battery is configured as 96 cells in series with 74 of these series connections in parallel. Each of those 74 provide 1/74th of the power out of the battery. Since the voltage has remained the same in going to 90kwh the capacity could be increased by using 78 in parallel. That would increase the packs power delivery by 78/74ths, the same as the capacity ratio. In any case since the voltage remains the same the only way to increase capacity is to increase amp-hrs. Typically, you can pull more amps as the amp-hr rating goes up, using similar chemisty.

Tesla has been talking about using new 2170 format batteries instead of the current 18650. They're only a little bigger in height and diameter so they might be able to pack them into the same foot print.
