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.

That's a bummer.

About data logging, the Innovate OT-2 looks intriguing.
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.
Nice find! Hopefully, I will not have to go to that extreme. It seems a bit pricey considering it is about 3 times as much as a 25 row oil cooler for the engine.
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
Which ap is this and what plug-in did you have to get to make it work? It would be awesome to have a cheap way to get accurate coolant and oil temps at the track. Wait, was your VVT oil temp accurate? I noticed you later mentioned your oil hit 282 degrees without going into limp mode?!?
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?
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.

Ok cool, I figured it was something like that. Thanks for the link! It looks like you might also be able to read and clear CE lights too? Any other cool things you can do with the ap? It sure beats the hell out of wiring up gauges and trying to find room for them in the cabin.
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.
A "simple" oil cooler benefits from having a pre-existing pump. The diff doesn't, thus the extra part and expense. Due to the small size of the exchanger and the difficulty in getting directed air to it, the kit includes a small electric fan. $$$.
