Hey TMC,
I'm pretty excited to show you our Cooling Party Controller that we've been working on. As you may know, we had some issues with our Long Range RWD car when we installed the rear oil cooler - the AC compressor decided the system was cool enough and stopped running! So we needed to find a way to get that "Track Mode" level cooling for AWD and RWD cars.
It took a fair bit of head-scratching but we did manage to get a Track Mode level of cooling (well, without the AC Compressor overclock) on our Model 3. It can also be used while charging and supercharging which is extremely useful for those of you that are charging at or near the track, as you can pre-cool the car for your next session and run for longer before overheating without any mechanical changes, and because the car superheats the battery while supercharging to increase the charge rate. Running the CPC 15 minutes before your supercharging session is over will bring the system down to ambient.
Here's a video with some more details:
This is one of the things that we're able to spend time developing when you guys choose MPP for your Model 3 upgrades, and we appreciate it a lot. And you'll see some appreciation of that on the product page if you read to the bottom!

Here's a quick overlay of Isaac's Model 3 (non Performance) where he ran with the CPC off on his first session of the day, and then again with it on later in the day when ambient temps had increased 10 deg C. When it was on Issac had started the session with the battery 8 degrees C warmer (you didn't precool for long enough Isaac!)
You can see that over the out-lap and two hot laps of Buttonwillow the battery temp only increased 16.5 degC versus 23 degC without the CPC. This is because the non-track mode car was not running the AC compressor the entire time, it was not running the water pumps at full speed, and as a result, the battery inlet temperatures were higher for almost the entire time - all of which can also be seen in the graph.
Thank you Isaac for testing this on the track for us while we've been covered in snow!
