Hey!
I guess you are here to find out more about me... so here goes

I drive a G37 Sport Sedan (rear wheel drive, 6 speed manual) and have a background in electronics, auto mechanics, vehicle networks (CAN bus), C/C++ programming and micro controllers.

Most of my time is spent on automotive research (Nissan/Infiniti) and trying to help others.

Thanks for dropping by!

The latest documentation I have is for a 2016 370z, and I don't think Nissan would have changed anything since. Based on the ROM you posted, your 370 is from 2017 and I would expect it to be the...

Is the cranking speed the same in each example? As for fuel pressure, her is what I have measured from my 2011 G37 last month: • When the engine is turned off it drops to about 46 PSI from 51 PSI...

Good news! However, the reason the ECM showed a high temp, was because of bad wiring. The engine oil temperature sensor (and the coolant temp sensor) decrease in resistance as warms up, and...

Those fuel trims look good. There is no harm in doing a idle air volume learning and it would be interesting to see if that changes anything. I don't know if turning off the O2 sensor codes...

Overall, it really isn't anything to worry about. I suspect the cause is your test pipes. Starting in about 2011, a "Rear Fuel Trim Monitor" was implemented in the ECM software. As the...

If the oil temp is showing a high temperature with the sensor unplugged, I suspect the oil temp signal wire is shorted to ground. To verify the wiring: With the sensor unplugged and ignition on...

Thank you for sharing the raw ECU dump! This will be VERY useful.

If you want to troubleshoot this yourself, get a cheap OBD scanner ($15) and a good OBD app like OBD Fusion.($15) Then you can find out your fuel trims which will tell you if your engine is...

There are two ways: (1) - Free and a little difficult (2) - Easy and ~$50 for an OBD scanner, OBD Fusion and the $15 enhanced diagnostic add-on (1) The free method is from the factory shop...

Generally VQ engines don't have cooling issues and work well for a long time. ^^^ Too bad you missed that red flag. Also, it is a little odd that only one head gasket was replaced.... or...

By the way, you new motor (B58) has incredible specs: • 11:1 compression • up to 26 PSI boost • variable valve timing • variable valve lift • variable oil pump volume • 2 high pressure fuel...
