Q about mixture menue: Hot PE vs Normal PE table

[2000ssnb]

It is not clear to me when, in the fuel mixture menu, the hot PE table is used. Clicking around it looks like it would be used only above
ECT = 255 F, a condition which never exists unless the engine is way too hot, fans aren't working etc. WHo would be driving above 255 F engine coolant temp in PE mode????

Is this a mistake - it seems to me that the hot PE mode should kick in
maybe around 180-200 F, or even lower.

Anybody have a clue?

Thanks

Like some other stuff like it's there cause some models use it.I use it on the s/c cars that I do.
I also use piston protection mode.
Basically its to add more fuel as hot engines have a tendency to detonate more easily.
