"Bogging" in first gear

DIGItonium · 06-08-2012, 01:59 PM

The 350Z definitely has better response down low. It is whiplash inducing. With the 370Z I had issues blipping the throttle on downshifts because it wasn't as eager to rev when I tapped the pedal. On the 350Z, it was easy to blip the throttle and get it revving past 3k RPM. It's all in the software from how I see it.

I think I noticed it more when I installed my Typhoon air intakes. But it definaltely happens when oil temps get hot. 180+ I hope to get a tune soon and I hope this helps fix this issue.

it's got to be related to engine temps and intake temps combined. I had this problem until I got my oil cooler, and tune with the radiator fan control. with the oil cooler alone the problem was still present. now that a tune and fan control has been done, I have had no issues with the throttle lag. oil temps never get above 200 even with aggressive driving.

in my sig, Stillen 19 row.

Does anyone get this BOGGING with stock airbox or CAI like Stillen G3?

I am thinking it might be heatsoak that causes this.

bushman66 · 06-12-2012, 03:03 PM

I have the stock airboxes. Only mod is the F! 18" Stainless CBE.

Yeah, really. Or maybe these guys that are bogging are taking off in 3rd? I find my car burns more gas when I rev it. Is that an issue?

If you don't have anything productive to add to the thread, don't post asinine comments. How about you read through the thread before posting and maybe you'll see this is a documented issue with the 370's...

I and others added productive comments in earlier posts. You have yet to report back. So, did you try launching your car at 3000 rpm with VDC off as was suggested to you? And how'd that work out? Have you gone to your dealer about this bogging? What did they say?

bushman66 · 06-15-2012, 02:58 PM

The gas pedal delay specifically happens when I launch normally, then "Punch it". One shouldn't have to launch at 3000rpm for the car to run correctly. A perfect example is if you are accelerating normally and have to floor it in case of an emergency.

I have tried this with the VDC off and it still occurs...but have not taken it into the dealer yet, primarily based on the 48 page thread posted above where others have taken it in and the dealer was no help.

Anyway...my apologies if my response was short, I definitely know how to drive the car, and am not taking off in 3rd gear. This is primarily a 1st gear problem.

I have noticed this does not occur in the mornings when the air temp and the car is cool...but as soon as it heats up...Bog city.

do you have an uprev tune? I know that the new fan control helps this alot. I had the same issue as well but since the fan control was "tuned" on my car the lag has all but gone away. this, coupled with an oil cooler has worked wonders.

This seems to be the only solution that I have read that (nearly) 100% solves the problem, so I'll add the 34 Row Z1 Oil cooler...then do the UpRev with the Fan control tune...

cool man, it will be money well spent. why nissan chose not to implement these two things in stock form is a mystery. hopefully it will resolve your issues. report back on the thread to let us know how it went when all is done.
