Temperature and limp mode question, may be silly

[2012Boss302]

I've seen S550's at the track enter limp mode because of excess temperature, either oil, coolant, or both. I've also read post here about S550 limp mode.

I have never experienced it or heard of S197's doing this. I personally have seen 260-270*F oil temp measured at the pan and 220+* F coolant temp using OBD data. No I am not concerned with my temps.

Is this limp mode phenomenon a S550 exclusive problem???

S197 will go limp mode at about 237 degrees Cylinder head temp. There are also subtle reduced power modes along the way, timing reduction and fuel enrichment. I believe tuners can modify these values in custom tunes.

I think the S550s have more sensors than the S197s in general, and Ford made use of the ability to go into limp mode if any of those monitored temps go too high. There were lots of examples when the first base 350s hit the track.
