Yes you are right the ECU does read it, but I meant it doesn't seem to have any direct correlation to pulling timing back like it would with coolant and air intake temp. Someone did mention it can change the VVTL, which is possible. Still from what I can see, ECU doesn't pull timing based on oil temp. Of course as oil temp goes up, your coolant and air temp already went up.
Remember limp mode is a rev limiter if I recall correctly, it doesn't just pull power
