Use Normal mode for faster warmup (and in frigid cold), and Sport mode for operation when warm.

I just posted something about this on one of the FB 991 groups and someone replied with this photo (not my photo) showing the water temp at 221F. Just trying to understand why it appears higher in some cars than 194F?

Yesour old and "slow" 991.1 cars..
You want your temps to drop, add the center radiator. According to friends with the radiator added, expect a 15 degree drop in fluid temperatures. If the center radiator is good enough for the 991.1 GTS, it's good enough for me. My local shop is installing it for about 3 hours of labor, sweet! Install date is September 8th!!!!!

On my 981 cayman, whichs uses the same setup, it would show 194F on the water until I hit oil temps of 275F or so, it which case I got water temp in the 221 to 224F range).
On my 991, I also have the center radiator, so I have never gotten my oil temp high enough to force the water temp out of the deadband.
