I turned off max cooling mode simply bc I didn't want to hear the fan blaring at random times. It's so loud I feel like people will think my car is overheating. So it's a self conscious thing for me.
Engine wear increases RAPIDLY as temperatures drop. And it's not even close to linear. (Wear doubles with engine coolant temps at 160F vs. 185F, engine wear is roughly 40x as much at 100F vs. 160F.) You'll also find the oil temps (in the sump) have a coorelation with the coolant temps and if you run the coolant temps too low it's hard to get the moisture out of the oil -moisture left in your oil causes varnish and acid production in the oil, which eventually creates engine sludge and deposits, especially with really long oil change intervals like in a BMW... Running your fans and electric water pump at full blast will also wear them out faster. People shouldn't be constantly using max cooling mode on their cars in the summer. This is best used between drag racing style runs to cool the engine back down to keep the runs consistent.
It looks like theres a few options for the max cooling mode. Off (oem), on, and original. Whats the difference between them? Also I'm looking for a licence for a n63t2 bm3.
Off means it is completely off, on means it’s completely on all the time and original means whatever the OTS map comes with pre made so it’s usually also off. I’ve tried original for a couple other options such as cold start and it didn’t turn it off
Absolutely can be 230 degrees F and that's the AVERAGE coolant temp. Near the hotspots just above the heads exhaust ports it will be locally higher still. A 50% Propylene or Ethylene glycol / 50% water blend's boiling point at atmospheric pressure is somewhere around 223F, but cooling systems are under PRESSURE and the boiling point increases about 3 degrees F for ever 1 psi of cooling system pressure. If you've got a 16 lb radiator cap the boiling point of that 50% glycol / 50% water blend increases to something like 244 degrees F.

The engine only lowers the temps in sport plus. In regular comfort it still goes up above 210 degrees both oil and coolant

Can’t be 230 degrees
Boiling point of water or blend is 212 degrees
