So, I just finished some initial testing of my latest modification to the yellow P85 (the one that has retrofitted autopilot hardware). Haven't gotten a lot of pics or videos together yet (roads have been wet from melting snow, so not great conditions for testing), but I can't resist sharing some initial details.
So far the car is a ~570HP RWD monster that desperately needs wider rear tires. It doesn't even have the staggered rims, so I'm putting this all through 245's at the moment and traction control stays on up to like 45 MPH. lol.
The car and everything in it are now running P85D firmware. The battery has been upgraded to a P85D Ludicrous pack. The car does not actually have a front motor, however. The front motor is being emulated by custom hardware and software that essentially tricks the car into thinking there is a front motor and that all of the power needs to go to the rear... and it does exactly that.
The performance rear drive units appear to have a max current of around 1400A. Ludicrous allows ~1520A, so even with HVAC on and such the motor can still max out.
In my testing at around 90% SoC and battery at about 32C the power maxed out at about 426kW. I plan on trying Max Battery Power @ 100% charge. Oh, and launch mode works too.
I finished up some code to make the car happy enough to not display any errors at all finally, but by then the pack was down to about 50% SoC. Did a few more test runs and snapped some photos of the dev readouts screen.
(Even at 50% SoC was still getting ~380kW/508 HP)
Hopefully roads dry up and I can grab the VBOX tomorrow for some testing at 100% SoC and a warm pack.
More soon.
(Yes, it's technically the wife's car.... although she uses the X mostly now)

Edit: Oh, and um... I may plan on offering this modification as a service at some point to P85/P85+ folks.
