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!

Code Definition as per FSM: C1109 ABS module low voltage B2562 BCM module low voltage As you can guess, low voltage can create many additional false codes. Check the connections on the...

The OBD PID for "fuel type" does not indicate what fuel is in the tank, it indicates what fuel type the ECU is programmed for. The ECU has no idea what fuel type is in use, since the car isn't...

Nice results! I'm surprised the stock fuel pump was able to provide enough volume. What was the maximum injector pulse width on E85 with the GT-R injectors?

Your rear O2 sensors need to switch between ~0.9 volts and ~0.1 volts to keep the ECU happy. If they are constantly at 0.28 - 0.29 volts they are too lean and the ECU will turn on the CEL. Since...

Track Addict supports OBD Mode $01 PIDs. There is no PID for "brake on/off" Here is a list of the more interesting items that are available: • SAE 0x0B Intake manifold absolute pressure • SAE...

The "Gear" is calculated from engine RPM and vehicle speed, so it should work on all vehicles. (Engine RPM and vehicle speeds are EPA/CARB mandatory PIDs) Harry's documentation refers to "wheel...

I don't think we are talking about the same part. To replace the valve cover gaskets, you don't need to touch the rad. You will need to remove the intake boots, upper intake plenum and ignition...

Be very carful not to over tighten the valve cover bolts. They are a stepped collar design (see link below) and can snap, leaving the threaded portion in the head. Also, tightening them a little...

If you haven't already, disconnect the ECU and the ignition coil #4. Check the resistance between #4 signal wire and ground. It should be open. I think the next step would be to temporarily run a...
