I have my temperature alarm set at 300F, in 5 years I got one alarm, this was while performing a Chandelle during a scale contest where the ambient temp was 95F. I normally don't fly when it is that hot, but in my mind adding a little fuel to hot engine can't hurt.
Right now, I cannot remember how I did that... But I do remember, that I made a programming set-up that increased mixture "proportionally". I later also used that same programming line to have a temperature sensor affect the mixture over telemetry. That was in the time Dave for the first time suggested a pressure/temp sensor in the plane for "atmospheric compensation". I did that as a kinda/sorta prototyping/proof of concept and to see whether Dave's idea would be practical or not.
If I remember correctly, that programming worked by means of running the fuel channel with its associated curve through an extra imput and having the measured value (or the knob/slider position) influence the "weight" function of that imput. but it is a bit hazy right now (long time ago, and this weekend I had a mishap that forced me to take quite a bit of morphine so my brain is not too bright today and probably for one or two days coming).
