Gas Pedal Delay

6spd

maybe there are varying levels of damage control, you know, rather than just what they tell us happens at 260?

Oil temp of 220F is easy to reference and reproduce the problem, but I have notice a little bit of roughness with acceleration around 200F. Hopefully I can schedule an appointment tomorrow afternoon. If you guys can, try to schedule an appointment with your techs for test so cases can be opened with Nissan. If they get enough complaints, then they can start looking into this issue.

Awesome. Today is the warmest day of the week. I called in this morning didn't get much luck scheduling another appointment.

After reading this I paid attention to my throttle response.

I have no delay what so ever.

it's a NISMO, but don't know if that matters.

I also don't feel the clutch issue people are talking about.

Zeto

What clutch issue?

IcedZ

Clutch issue? In this thread or another?

I called my service dept. and the tech says he does not need to drive my car at the moment. Nissan does not have a fix for this issue, but he is also trying to do some more research.

To reiterate, I would like to encourge everyone who has this delay/power issue to schedule a drive with a tech so the complaint can be logged. Hopefully Nissan will issue a fix.

That's true, boost building up around 2.5K and beyond pretty much offsets that issue. How's the oil cooler treating you?

All, I just got a call back from my service department. The lead tech called Nissan Tech-Line, and the reason for "power cutting" is due to oil temperature. Suggestion to remedy this issue? Nissan offers an accessory oil cooler. They also suggest using the magical ester oil to further remedy the issue. I'm not surprised by any of this information, but I am relieved that it is nothing serious like VVEL actuator failure, sensor failure, etc.

There you have it guys, one of our primary suspicions since the beginning was: OIL TEMPERATURE.

i still think they secretly put varying levels of "engine protection" in without telling us. Like small steps in power reduction as oil temps creep past 210-220. its a possibility?!

Yea, 220F is the norm that I see when daily driving in 75F+ ambient (after 30min of freeway and stop-go city traffic). You would think they would start cutting power beyond that. My butt feels a difference in 2nd and 3rd around 200F. But yea, that pretty much explains why I can't light up the tires rolling in 1st when the oil temps are close to 220F.

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).

It definately takes a few WOT pulls for the car to really give full power as the ECU adjusts to different driving styles. As the temperature went up, I could feel power going down without a doubt not to mention slower throttle response but I never got hang ups while revving nor the type of power cut you have.

Getting an oil cooler made all the difference for me, keeping the oil temperature down around 180 makes the car feel like an animal with noticeably more aggressive power delivery and throttle response; have you considered getting one?

Your temps stay around 180? I have an oil cooler and i hit 200 regular driving... sometimes around 210. Keep in mind.. it used to be 220 regular driving and would get near 230.

What size cooler do you have? I have seen maybe 200 while sitting in traffic for 30 minutes but as soon as I start moving, it drops down to 180-190 in city speeds and below 180 cruising on the highway. Maybe your ambient temperatures are higher too being in TX.
