Low Speed Bog w/ 7AT
#47
I do not know if it helps you guy. I went to deal again ,and one service manager suggested me to switch to 93 as I was using 91. He explained that the premium gas provide more power when spuring to the engine so less bogging . I am not sure if he is right , however, after 2 weeks with 93, I would like to say it does not make bogging total go away but helps improve at least 60%

I use 93 all the time. If you use less than 91/93 octane, the engine may knock, which will make the ecu retard the timing. The main problem in my mind is that the 7AT when driven mildly will upshift to 6th or 7th gear as quickly as possible. When you're driving 30-35 in full auto and in 6th or 7th gear, it has a tendency to bog.
I rarely ever use full auto anymore...too annoying in traffic.
Thanks for the update.

Using DS doesn't solve the problem, I've tried. Just because I'm in DS doesn't mean I wouldn't like a QUICK downshift at times. All DS does is keep you at a higher RPM/lower gear. Whether in D or DS, this transmission bogs down at times, giving you a nice 1-2 second delay before downshifting. This delay/bog has caught me off-guard a few times. Imagine hitting the gas, thinking you are about to accelerate quickly so you can merge into traffic, only to go no where. I'm not a nit-picky person, but aside from being annoying, it seems a little dangerous to me. As far as re-writing the tranny code....I would love for that to happen, but that's someone else's job(Infiniti). You seem to be implying that this is normal; I would hope not. My car should downshift when I want it to(whether in D or DS).
Combine all of these things and you get some throttle hesitation in certain gears. My tune, which is pretty good for a canned tune, and not as good as a custom dyno or an uprev, still does and excellent job of getting rid of the throttle hesitation (and adding some low-end torque). It's till there a little, but that's due to the tranny/mechanical things that can't be controlled. But that what I recomend to solve your issue.
