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!

Let me back up to understand the background: You had a misfire and replaced all the fuel injectors. Since then, the car will crank more than usual before starting ONLY if it has been sitting. Is...

The fuel pressure drop you have is normal. As long as you have 29 psi or more after 30 minutes with the engine off, all is good. You may want to check the fuel volume. The stock pump is around...

After doing a lot more research on ICE MODE, it isn't a brake booster issue. It seems to happen on multiple OEM ABS modules when used in track days / racing. A common tigger seems to be multiple...

For the 370, here is the location of the check valve / one way valve: (This valve only allows air to flow out of the brake booster)...

Interesting... Where did you connect the vacuum canister to and did you happen to measure/view the brake booster pressure or sensor voltage? (I assumed you didn't, but wanted to verify) I'm...

Over the years, there has been a lot of talk and worry about "ice mode". I don't know why, but I find this topic very interesting... After reading this thread...

Sounds like you are pissed at Nissan for some reason... Who going to spend $130+ for a STATIC update, when you can use you phone for "free"? They are simply wrapping up the NAV business since...

I data log EVERYTHING on my G37... In looking at the data and doing some quick math, here is an average temp increase from ambient temp: • Engine coolant temp increases about 32F/min (18C/min)...

When you post the dyno sheet, we can see what your HP/Torq is corrected for elevation (pressure), temp and humidity. Most dynos use the "STD" correction factor which adjust the conditions to sea...
