When does Limp mode kick in for over heating?

natedog7700 · 02-27-2017, 12:06 PM

With the 335's, at which temperature does limp mode kick in for over heating? Is it based off coolant temperature or oil temperature?

My water pump just went out a week ago. My coolant hit 250 F and went into limp mode.

I believe water temp is two stage. Yellow limp mode at about 235 and red shut down at 250ish.
Oil temp will also cause limp mode independent of water temp. I believe oil temp limp mode trigger is about 275.
I cant verify either by experience, but have read experiences from related blog entries.

If you open a stock bin in tunerpro you can view all these settings and modify them too, including coolant temp setpoints and fan dutycycle.

Not sure about water temp, but on a trackday at Le Mans last year the oil hit about 140C (285F) and it didn't go in to limp mode. So not sure what temp it would kick in.

I also have hit 280-285 on track/ canyon runs, and not gotten limp mode.

Ive hit about 250 oil temp with no limp mode a couple times. Never higher though.
