Is this normal?
Just wondering if it is normal for the REVS to jump high and the car not move anywhere when you try to floor it in the D (Auto) gear on a 7sp Auto? The Revs will jump high and the engine will roar but not actually move anywhere for atleast 0.5-1second.
This happens almost always in D gear if I try to floor it, but it doesn't in Manual mode and takes off normally in manual. Are we not suppose to floor it in D (Auto) gear, or could there be an issue with my Zed? I have a 15' 370Z. Sorry if this is a noob question, I am pretty noob with cars. |
I think, it's the auto computer not being able to keep up with your demands. Usually this is one of the major reasons why people get manual cars. The response time is far better, you're always in control, you save gas, fixing is cheaper, they accelerate better and you can push them to higher RPMs and they genuinely last longer (depending on driving style). My step mom had the same problem with her dodge nitro and I also experienced it with another auto car that I drove.
Basically as you're going and want to suddenly punch it, it's as if instead of downshifting it stays on neutral instead for like a split second and your RPMs shoot up... Then the gear kicks in and it's back to normal, Correct? But it's a major buzz kill if you want to pass someone or suddenly take off... Yeah it's normal, at least in my experience, I guess it's the computer trying to protect your tranny... Sent from my iPhone using Tapatalk |
Throttle lag from your ECU. Get it tuned and it's gone.

doesnt dat have to do with the torque converter stall speed?

7sp auto has it Anyways, this lag delay and loss of power in D kind of sux. Today there was an R33 Skyline that crept up behind me and then flaw'd it infront of me, and I thought I will kill him until I dropped it on this D gear and my revs just flew. I was like damn, I am suppose to be in manual mode :( Now that driver of that R33 thinks he killed me ;( Kind of off topic, but do you guys rekon I should paint the stock Ray's Engineering rims black on my 15' Z or keep them with original shadow chrome? I seem to be witnessing a lot of Z owners here in Aus colour their stock Z rims black, it does seem to bring out a more mean appeal. When I ask my friends here, they say nahh don't do that keep them original. What do you guys think? |

hmm i've had autos, but i noticed if it's from a stop then it's fine, but when you're rolling it's just the lagg time for it to figure out that you're flooring it and it needs to down shift, rather than stay at a higher gear to for cruising

Manual?

The engine and transmission act differently depending on how you have been driving and what mode the transmission is in. I suspect what you are seeing/feeling/hearing is the car switching from "cruising mode" to "aggressive mode." YMMV |
Lol @ the innuendos. You know, you can just hit the paddles and it will go into manual mode, you don't need to put it in "S" It will even revert back to auto mode after flogging it. It's good for the occasional @ss hauling and then back to a normal citizen. At least my Wife's Maxima SV Sport model has it, I would assume the auto Z's do too.

@SS_Firehawk - I've read about cars de-tuning themselves when people drive like they own a prius. OP just pull your battery for an hour to factory reset it. turn back on your car let it idle a minute or two then go on the road and WOT and do a few good pulls? |
Quote:
also to the OP idk if it was mentioned but to this asian's post the AT/ECU somewhat "learns from the way you drive. if you're always in D and drive normal/slow it'll sorta lean to that style of shifting and when you go WOT it's gonna hesitate and oddly shift. |

after my break in i just started driving hard and i only use manual mode. i think i've used auto mode maybe 50 miles total of my now 50k on the clock. |
I'm running a 7AT and I don't experience this! I do feel a little more power in manual, wether from a stop or as I'm driving, but there never any lag. As soon as I floor it, my Z takes off! Even in auto mode. That sounds like it could be a problem!

Not sure how long it takes to switch to "cruising mode" but if you put the xmission in manual mode and hit the gas hard, it will go into "aggressive mode" almost immediately. There may a description of how it works in the FSM. |

i DD mine so typically the top speed i hit going to and from work is 60ish on 2 stretches. i dont even use highways for my commute. but there's times where i lay into it and shift at high rpm and launches etc. also i have some nice curvy backroads where i live so i hit those in a "spirited" fashion lol |

Not to interrupt the hilarity that is sure to continue in this thread, but a gentle reminder to the OP that discussion of street racing 'kills' is prohibited on this forum. :shakes head: Now back to our regularly scheduled trolling of the OP... :owned: |
I got killed by a fiat 500 going to 60kmh =(
oh and killed by the prius. and then after that an mdx. should of got a mustang :stirthepot: |
Wow lots of interesting things said here. So basically because I drive it soft/casually most of the time, that is why auto feel laggy when it is given full pedal.

Quote:
If in full auto then most likely. Drop it into manual mode and should sort itself out since you control the shifts. |

Yea thats what I mean, because I am always driving it soft in full auto, i only gunn it full pedal maybe once a week or 2 weeks.
|
Gun it a couple of times *before* you want to drive aggressively. This will prompt it to switch modes, and it'll be ready for you when you want it. Note that if you're doing this on the street, slowing down between stretches can possibly put you back in cruising mode.
