Is it possible that the ECU is starting to detect detonation at those elevated temps and triggering limp mode?
On the subject, there's a new contraceptive pill for men. It's quite large and you put it in your shoe.
It makes you limp.

@AZ_Ryan as well
I'm not sure the exact temperature but for sure it was 280 or above . Before you hit the limp mode the whole oil temperature gauge will turn orange since it is with in the small orange area. once you pass that - and its a matter of seconds to pass it if you are already there - the car will loose significant power with no any notification the dash (or at least I did not notice). You need to let of the gas and allow the oil to cool for some time (10-20 seconds) and then you have full power again. It has happened to me few times in spirited driving in back canyon roads
. I have noticed that in both my old and new engine (I got my engine replaced) .Also lately I have had a faulty CHT sensor, which out of the blue , with all the temperatures being normal , it completely cut power (it didn't even let me shift gears ) and threw all service messages in the dash ...I had to delete the code to be able to drive the car....
This car is amazing and trash at the same time. thats the paradox
PS. My car is a non performance pack with an oil cooler installed from Ford performance. And yes, I did not see any oil temperature differences before and after the oil cooler installation. And yes the oil overheated even after installing the oil cooler. Was the oil temperature reading real with the oil cooler real ? - probably not ...I measured the input / output of the oil cooler and it had about 30 degrees difference ,which means the cooler is working but the system/algorithm does not take it into account
PS. Now it made me think again.. When I got the new engine replaced, as far as I remember they kept some stuff from the old engine, like intake manifold ,injectors etc...and probably could have kept the CHT sensors...if that is the case then most likely what I experienced could have been the result of the faulty CHT sensors and in combination with elevated oil temperatures it gave the signal that the engine is about to explode and reduced the power.....Could be a possibility... Next time I drive it hard I will let you know

Yep. The oil is cooler than the ECU makes it appear on your display.
Maybe the market is too small for some enterprising young entrepreneur to come up with a viable solution for the aftermarket.

Wow, you are not kidding about a long road trip with a trailered track car. South Georgia to New York.

2,155 miles calculated from home to each track then back. I figure by the time we travel back and forth between the track and hotel/restaurants, the trip will be over 2,500 miles. It should be fun, though.

On my '87 Camaro, I installed oil temp and transmission temp gauges in an A-pillar gauge pod since I drove it on road-race courses and as a daily driver. The Canton oil pan had a fitting for the temp sender. I used an Autometer manifold tied into the trans cooler lines for the trans temp sender. I can't imagine not knowing the actual temperatures when out on the track...
