"Bogging" in first gear

DIGItonium

It's even worse with the A/C running. There are times I'm literally flooring it and it's barely achieving warp speed with the turbos haha.

its normal, it has to due with the throttle response and the amount of fuel being dumped into the engine. Its no different than trying to floor it at 50mph in 6th gear. There is a certain timeframe (speed to gear or rpm's to launch) that your car will respond best at. I launch my car at almost 2k and it takes off fine. What people are also failing to realize is IT'S NOT A V8! Dont expect to get your head shot back upon take off, unless you rebuild the bottom end of the car and force induct the car.

and like the gentleman stated in this thread, a lot of us have put 2cents of good info in but you hvae yet to report back.

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).

cheshirecat

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.

Phaddi_inc

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.

You clearly have not experienced this issue on your car. You either have an AT or are blessed to not have it on your MT. No need to have a V8 to overcome this. Lots of cars that are not V8's don't do this and do not bog off the line. I have a V6 Isuzu Rodeo and it comes off the line great 100% of the time. Not so much on my 370Z. I have Civics and mini vans that come off stronger off the line when this issue happens on my Z. They make me look like an idiot when it happens too. Like others said, when the car is cold, it's fine. It's when it gets "HOT" it does it bad. And yes launching at 3,000 RPMs helps a lot. But we shouldn't have to do that to overcome this issue.

I recently had this happen to me in some stop and go traffic on a warm day. BOG CITY. It is definately due to overheating of the engine.

To the OP:

You've got a 2012 Z with no factory oil cooler? I thought all of them got it installed as of 2012 production year...

I'm about to get my 2012 Z in the next couple of weeks... eeeek

bushman66

The oil cooler on the 2012 is an oil-water intercooler that is as worthless as the proverbial t*ts on a bull. I routinely see 230 degree plus oil temps with normal driving here in AZ (~110+ temps). I plan to remove the factory sandwich plate when I get around to adding the Z1 34 row cooler...mainly because I've read that its a PITA to remove the filter with both plates sandwiched together...

Zrider79

So a 25 row oil cooler should fix this for daily driving.....is that basically the solution ?

BlackZeda

I had a Stillen 19-row Oil Cooler installed which greatly improved (if not eliminated) the bogging issue...oh yes, my NISMO would bog bad in the heat.

Stillen 19-row Oil Cooler installed by MAC Autosports review

bushman66

I'm going 34 row, and UpRev tune with the cooling fan tune. I don't believe an oil cooler alone will fix this...I read in the other thread, that someone has the 25 row oil cooler (no tune) and still has the delay 100% of the time. Hell...I'm not even sure the oil cooler AND the tune will fix it, but from other posts here, it sounds like it does improve it dramatically.

SOOO pissed at Nissan for not addressing this properly...

BlackZeda

That should do it I wonder if the NISMO has a bit of an advantage since it has such a big, unobstructed "grill"/intake. The installers said that they didn't have to do any trimming whatsoever even though the Stillen instructions indicated that it would be necessary.
