The G37S is a great track car

Mazda does the same thing, using the ECU to drive the coolant temp and oil pressure gauges. You need data logging to know real temps. Oil temp gauge kit should be easy to acquire and install.
Us 7AT owners are screwed again. The three-pass(!) CSF radiator isn't available for the auto. We have to suffer with the two-row single-pass exchanger.

I went with the Z1 diff cover with cooling fins and more capacity and I upgraded to Redline fluid. Hopefully, that is enough to keep it cool. Last year it got so hot it actually melted the ABS sensors?!? The diff cover has plugs for a cooler, but I no one makes one specific to our cars yet that I know of. No idea where I would find room to mount it either.

Yup, confirmed that it reads VVT Oil temp. See screenshot below. You DO need to purchase the Infiniti plugin as the default "Oil temp" metric does not work with the Infiniti ECU.
Unfortunately no indication of an oil pressure reading.
If anyone is curious, the readings below were after a cold start, 10 min city drive (ambient temp 56F), and idling still for a few min.
Oil temps seem to consistently rise as the engine is used. Coolant and intake temps will rise when idling and fall when moving, which makes sense. Accelerometer is off because you need to calibrate it to the phone's current position - this also means that if I want an accurate accelerometer reading at the event, I will need to strap down my phone somewhere :P

Thanks. So I assume it is Torque Pro and not Torque Lite? I see the Advanced EX for Infiniti plugin for the ap, but how does it communicate with the car to get coolant and oil temps? I cannot imagine it can do that via bluetooth. Do you need something else to plug into the OBDII?

Correct, Torque Pro is required to get the extra features.
The plug-in tells the app how to map the PID to read the ECU correctly.
You need an OBD2 scanner to talk to your phone, there are plenty that connect via bluetooth and I use and like this one:
It has a higher scan rate than the cheap ones and it has lasted several times longer than the last cheaper one I bought. There is an iPhone version of the scanner too if you swing that way.

So is the ap accurate for oil temps? I noticed bsanalyst mentioned he was hitting 282 degrees at an autocross which seems crazy high. I believe someone else mentioned earlier that the car usually goes into limp mode around 240-260 degrees.

Yeah, but you have to get the fluid into the cooler and back to the diff. I imagine their setup has a pump of some sort and possibly thermostatic control.
