I'm talking about OIL TEMPERATURE read by the ECU being used as a basis for limiting engine power output in some way.
I'm not talking about intake air temperature (IAT) or engine coolant temperature (ECT). Yes, lower IATs will generate more power & vice versa, and there's a range of optimum ECTs too.
I guess what I'm trying to get at, is that we have people on this site stating that when engine oil temperature rises above a certain point, that the ECU will start limiting power output in order to protect the engine. What I'm trying to find out is if there's any documented proof (such as dyno runs at different oil temperatures??) to back those claims up?
