First potential problem?

This indeed is a problem. I was talking about it in the other thread. MCR is working on a solution for this. I hope they come out with a reliable solution. Namir posted in his other post that STILLEN is also working on it.

I think it limits revs to 5-6k or something. I can't remember details but I remember some people complaining about it on MyG37.

It looks like an oil cooler will be a necessary upgrade for any one interested in tracking?

"TORQUE CUT CONTROL (AT HIGH ENGINE OIL TEMPERATURE)
ECM receives engine oil temperature signal from engine oil temperature sensor.
To avoid VVEL performance, ECM performs the engine torque cut control at high engine oil temperature.
If engine oil temperature is too high, engine oil viscosity will change. As a result, engine oil pressure is
decreased. This control is to control the VVEL operating angle by operating the VVEL actuator sub assembly.
If this control is operated, engine performance will decrease, then maximum engine speed is reduced a little,
for example.
NOTE:
If the engine oil temperature sensor is deteriorated, its characteristic will change.
In this case, the operating temperature for engine torque cut control might be decrease.
Perform Component Inspection of the engine oil temperature sensor to check for the deterioration.
Refer to EC-248, "Component Inspection". "
