"Bogging" in first gear

bushman66

I have reported back. And the thread has NOTHING to do with "getting your head shot back". It has EVERYTHING to do with the car falling on its face, due to the SHITTY Nissan ECU tuning for a period of 1-2 seconds before the engine catches up. God forbid I ever need to punch it to avoid an accident or something. This car is BLATANTLY unsafe the way it is running now. PERIOD.

I am willing to add an aftermarket oil cooler, or an aftermarket tune, or both, as necessary, to correct something that NISSAN should have addressed LONG AGO. This has been an issue since the 09's came out...

Yes i agree, Nissan should have added an oil cooler from the factory...having said that, Im done stressing over it. Im getting my oil cooler next week, and in July im getting the uprev tune with the fan control mod. I believe its all related to oil temp and heat soak. Hopefully that will solve 90% of the problem, and i will be happy.

To those who disregard the problem as 'normal' or bad driving habits, clearly you have not experienced this issue. If it was a normal characteristic of the car it would happen all the time and not sometimes, and I certainly hope anyone who has purchased a 370Z knows its a V6 (not a V8).

Yes. And to say this is "normal", or is due to the drive by wire, or some other reason other that NISSAN's SHITTY ECU programming is patently FALSE. My Twin Turbo Porsche has drive by wire, and does not suffer from any gas pedal delay due to heat soak or otherwise. My Chevy Silverado does not have drive by wire, and it does not does not suffer from gas pedal delay.

You nailed it Phaddi...its up to the private owner to fix a problem that NISSAN should have addressed 3 years ago. That's what I will do, as I do love the car otherwise...its just a shame Nissan continues to offer a car that is 95% done (as witnessed when Car & Driver stuffed a NISMO into the wall during a track day shootout due to inadequate brake pads...that is inexcusable for a performance car).

Agreed. Couple this with people stating it gets worse with oil temp and I think you've got an ECU that overcompensates when it comes to percieving damage to the powertrain due to high oil temps.

well it is what it is I suppose...I knew about the lack of oil cooler before purchasing the vehicle (still went ahead and purchased it), and figured if needed i'll install one. Most reviews I watched mentioned it, and Nissan even included coolers on some Zs they had leant for review. At some point I was in denial because I dont track my car, but after a couple mods and a bit of spirited driving (or 5-10min of trafic), I realized its a must. There may be other issues with the ecu/drive by wire/stock tune, but im just gonna keep it simple and get this cooler asap. Once its installed and the uprev tune is on i'll report back.
