At 23.5 MPG, you can sorta see what my driving habits are. It's just casual everyday driving. Even in that scenario the ECM is cutting power which can take my by surprise while making a turn or merging and having minor trouble keeping up with traffic (i.e., not as fast as anticipated).

I'm not sure I'm buying into that story from the tech whole heartedly. Yes the engine is going to cut back power indirectly by pulling timing as the intake temperatures rise, but not as severely as your car seemed to be experiencing. I mean I can beat on the car at auto-x or at a race track and have never really encountered the problems you are experiencing, and that was with the oil temp hovering between 240 and 260.

You're right. It is a very noticeable problem, and it is pretty bad during the summer. When I give it more gas, the exhaust gets loud, but the car doesn't budge (i.e., feels like accelerating in too high of a gear).

As weird as it sounds for ambient temps averaging upper 60s to lower 70s this time of year for daily driving, I may get one. Either way, I'll be getting one once I pull the trigger on the F.I. project early next year. I've been a bit hesitant to go F.I. because of these issues. Based on your experience, if the oil cooler keeps me under 200F in daily driving conditions and resolves these power cut issues I'll be happy!

That's the weird thing. Some people get it and some people don't. Have you seen my YouTube video demonstrating the cut in power? It doesn't take hard driving to notice power being cut. However, as others may have jokingly mentioned, simply drive above 3k RPM and it'll be fine.

Yup, same here. And it's usually under 3.5K, correct? Oh, and it's really bad if you're stopped on a serious incline and try to get going.

That is still weird though how I dont feel what you are describing, meaning if it is an engine protection sorta mode, I'd have the same experience. I dont doubt you by any stretch of the imagination and I have been very vigilant and aware when Im driving, consciously looking for the problem, but I havent seen it yet.

are you gonna try an oil cooler?

Well this is not good. I have had the Stillen "race" oil cooler since it came out and I still get this gas delay problem because my oil temp still hits 220 in city driving...yea I drive aggressive. I am soooooo disappointed with Nissan. GTR had issues with tranny/launch control and now the 370Z has more issues than a 20 year old Geo Metro.

-gas pedal delay
-oil over heating
-Ice mode braking issues (this has not happened to me yet)
-ECU whine noise (this has not happened to me or my car is too loud to hear it)
-Rear hatch sticking issue
-windows rolling down on their own
-oil consumption

This is not cool at all.

WOW, how did I get so lucky... I think I have (or had) ALL of these problems (except Ice mode braking? - What's Ice?)
I didn't look into it, but my driver window goes down a little bit randomly. For the longest time, I thought it was me bumping it or something!

Anyway DIGI, thanks for the info. I'll see if my dealer concurs. I'm not going to tell him any of this since I want them to come to their own conclusion.

get ECU tuned and problem solved.

^ They should talk to Technosquare.

I know...

But my real point is that Nissan has a screwed up product. It shouldn't be this way in the first place. But since it is, they need to address it. I shouldn't have to spend an extra ~$1k out of my own pocket to fix THEIR mistake.

But you also have to remember that 90%+ of regular 370z owners would not notice the delay at all and are plenty happy with the current throttle response. Does that make it right? No, maybe not. Then again, look at the oil temperature issue which is not being addressed by Nissan because the majority of normal owners do not push the car to the point where it becomes an issue.

UPS or FedEx will get your ECU there.
