I can provide you with an IXXAT dump of an AWD if you want something to play with.
Mike, do you have the data files/excel sheets on your google drive? i think if you matched up the BatI currents as the start point then you would see how the torques peak and then the L jumps ahead on speed from the benefit of the extra 200 Amps. i might play with the data some if available, although i like your charts better than mine.
For the shorter burns from say 30-70, the current doesn't seem to ramp down at the tail end like it does with 0-90 acceleration runs, maybe less thermal load?
Look at the extremely steep slope of the current during the first 30msec after you release the brake in LauchMode--that is an insanely steep ramp up for a short time, and the Rtorque nearly instantly increases from 350 to 450 ft-lbs. That slope and the torque response are nearly identical in the before and after L charts for run after run, and one car to the next. i agree with Bill that it is programmed into the system and they are pushing it to the bleeding edge.
Probably something in the system (mechanical drivetrain?) is causing it to be limited at that 450 peak torque level, but the motor could easily produce more since it only takes 200 Amps for both motors to hit that peak.
Note that speed (right axis) is in KPH, not MPH. 77kph to 159kph, 100% TPS, on a private road, which is also kind of narrow : this was a bit scary.
SOC was 88%, outside temp was pretty cold (-10C)
Max amp draw is 1164A
Max Power is 356kW
edit : woops, forgot to add : green is voltage, red is power and blue is speed.
kudos to wk057 for helping me with the stupid 15bit signed integer this morning!

Same graph, with Current instead

Nice graphs. Don't suppose you have the torque plots for the front and rear motors? (This is where I'd expect the biggest difference between the 85D and the P85D)
(I have the C# source for those messages if that's what you are using)
Yup. Looks like it.@llavalle - There are some odd jumps and gaps in your data by the looks of it. Is that the CANtact having trouble keeping up with the high data rates?
GUI_dragStripModeRequest,true
VAPI_dragStripStatus,Heating
VAPI_dragStripTimeEst,39
*waits patiently...*
Perk of having a rooted car: can do everything remotely.
Wait, what? wk, you took yours into a Tesla service center for the ludicrous upgrade? And they didn't give crap about having a rooted Model S?
When are you starting your reservation list? I'll take one. Do you want any data from a P85 Sig still on 6.2 (or just the P85D that has a Lud upgrade pending)?Cool!
Although, for production runs like that I go to a friend who works for a company that has a turn-key setup. I give them the PCB design and BOM, they source it all (either from me or whoever), bill me at cost for the BOM items, and build however many I want, from 1 to 1,000,000. Generally only cost effective for 100 or more though.
Holy crap. Says 475kW max available.........
If some of the logic is shared with P85D, then it makes sense that the front motor is designated as the more efficient go-to motor for range optimization.Rangemode = front motor only on a 85D too (odd...).
I'm looking at the first graph at the 1.5s mark. It appears that the front torque is dropping while the rear torque is rising.Updated/better 50-75 graph (I snuck in a capture this morning). I feel a lot happier with these, re. SoC, BatTemp, etc. etc.
