I personally don't feel it takes away power at -10. I don't trust myself enough so I asked a pro driver on the Ring if he feels that TC limits power. He said that it does something with brakes, but he believes it's just ediff works to stop wheel hops and he didn't feel any TC related power cut. Without track mode or even at 0 stability control with TM the power cut is undeniable even it releases full power much faster than on ICE. As far as I know MPP doesn't claim there is any advantage in party box vs track mode except ability to run full power cooling while finishing supercharging. And I hope that Tesla would eventually add this option to keep track mode while in charge, because you really lose a time and charge between rides or have to go with everything too hot.
Ah, right, still 2 separate boxes. This one is clearly of no value for M3P and it's not completely switching off TC.
One of our customers just unofficially broke the lap record at a track in California using our PB on a Performance Model 3. They also have the MoTeC display so when we get our hands on data we will be able to confirm whether it really is faster or not. The driver said it is faster, but that isn't quite enough for us to go on yet!
They also have the Cooling Party Controller, so Track Mode isn't really necessary for them if you are referring to the AC overclock function!
Once party box is installed, can it be disabled on MCU via software to drive normally on the street off the track?
It is just a connector that will plug-in in the place of the Partybox or Cooling Party Controller, returning everything to stock!
