New member and reformed "lurker" here.

It doesn't look like there is a specific place for cooling system questions so I'm posting it here. If this is not the appropriate place to do so, please redirect me.

I know that as far as OEM goes that getting the 2nd compressor (Max Tow option) is the best way to ensure maximum cooling of the electrical/propulsion system. These questions are meant to be for either 1 compressor or 2 compressor systems.

As a current non-owner, and future purchaser, of a Lightning I'm wondering:
What temperatures can you monitor onboard? Batteries? Motors? Coolant/refrigerant in the compressor system? Coolant/H2O in the "radiator" system?
Has anyone made any mods (or looked into them) to improve the cooling efficiency? Larger refrigerant/H2O chiller? Larger radiator? Other methods to cool the radiator more quickly? For example, in the "old days" as an offroader in southern AZ we would direct the windshield sprayer to the radiator for extra cooling as needed. (Very redneck/low-tech for a Lightning I know...) Maybe there is a computer hack to have the system cool down more than usual in anticipation of a high-heat event?

My main reason for asking is towing heavy loads on mountainous terrain in a hot climate, but I wonder if increasing the cooling could help with rapid charging as well?

You can monitor a bunch of temps with CarScanner and an OBD adapter.

Best to see if there is an actual need first, I've towed in 100deg+ temps in NE OK in the base of the Ozark mountains and never had an issue with my standard XLT without tow package. Get CarScanner and you can keep a close eye on all the metrics that are key:

This was recent, as you see it's 10deg outside and my battery is also cold, I can tell coolant isn't flowing b/c notice the battery coolant input temp is colder than the battery. During the summer when coolant is flowing all the temps better synchronize. I don't have a heat pump, but I'm interested to know if they are pulling heat from the inverters and motors, the battery sure doesn't generate any heat from normal driving.
