I'm wondering the same thing. On the GT4/Spyder, the water temp goes straight to 105C as I'm negotiating the town, and then when I get away from town and start to drive more for real it will come back down to ~90C. My understanding is that when it's not under much load, they go to the higher temp for emissions reasons. And I don't think there is a way to change that behavior (since I don't have a "sport" mode).So, I've wondered this... for those of us with only sport mode option (manual transmission here too), is there an advantage to the cooling feature that comes with the functionality? I do not press Sport until I've reached 205 F under normal and did not use sport for the majority of my break-in period... and I actually enjoyed the normal driving mode then too.
But I wonder what the tradeoffs are, besides emissions?
