It's good to get some correlation from others. I've been seeing 240 F coolant and oil temps with regular driving, while in my RX-8, 220 F (no oil temp) was considered pushing your luck. I have to recalibrate my brain.

This morning, I did find a few years old N55 reference (pre N55B30o0) that listed temps for system protection:

Component protection
-coolant temp between 117C and 124C (243F to 255F)
-engine oil temp between 150C and 157C (302F to 315F)
-result: output of the air conditioning system (up to 100%) and of the engine is reduced.

Emergency
-coolant temp between 125C and 129C (257F and 264F)
-engine oil temp between 158C and 163C (316F and 325F)
-result: the power output of the engine is reduced (up to approx 90%)

I'm trying get Torque's display to match the car's somewhat. I'm going on a compromise between day and night modes. The cabling tucks under the front tray mat without popping it up, but I couldn't run it through the ashtray hole on the passenger side because there's some plastic under it. A smaller right angle cable would be less intrusive, but this one's thickness keeps the phone from sliding. The oil gauge is blinking due to "low temp" so it looks like the needle or reading is missing in some pics. The 240 "red zone" for coolant will probably get tweaked some as well.
