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!

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...

The G37/370 oil temperature is an EXTENDED PID and the ECU needs to be in to diagnostic mode in order to recieive a valid response. This is very easy to do. This video show how to set up the...

Quick question: If you increase the pump volume and retain the stock fuel pressure, won't that just heat up the fuel faster, since more volume is being pumped over and over, verses being burned in...

I hope that your CEL stays off, however 100 miles is not much of a test. The newer ECU control strategy will detect the test pipes and throw a CEL of "too lean" due to the post cat o2 sensor being...

The newer ECUs have a different control strategy to check for a lean/rich bias of the air/fuel sensor, using the post cat O2 sensor. With a test pipe and the "anti-foulers", the rear O2 sensors...
