Gas Pedal Delay

chops · 08-11-2012, 06:30 PM

not sure if anyone's tried this in here, but i filled up with 10 gallons 91 octane. 5 gallons 100 octane (effectively making for about 95 octane) today just to see if it'd help with the hesitation in low RPM's. didnt do much. although i feel that it did make the car more responsive at highway speeds.

no hesitation for me and the car didnt lose any power.uprev fan mod is a must and i will be getting that sometime in the near future.for now,my temp fan mod stays and when i get ready to do some very spirited runs after car is fully warmed up,ill hit the switch and im good.

highest i seen my oil temp after this mod tonight was 210 where it should have been 225-230 with how hard i ran the car.it was 65 degrees out but the fan mod is still needed .25 row oil cooler before next summer and this hesitation should be completely gone for me.nissan surely made a big mistake programming the fans to come on when they do.thats 75% of the problem imo

interesting. i have a 25 row oil cooler and my oil temps never saw above 200 degrees after a 2hour run in 100 degree ambient temps. however..i definitely got the dreaded gas pedal delay when between 1-3k RPM.

any chance you can show us how you did the fan mod? i'd LOVE to do it on mine

you will need;

one fuse holder with 12 awg wire and fuse
around 24ft of 12 awg wire
one 50a toggle switch(2 prong,not 3)

i will mount the switch tomorrow in one of the blanks by the cup holder.i had it laying in the seat tonight testing to see how it worked before mounting it.hope you have some patience cause you're going to need it.make sure to keep the switch off when you are running the ac.

Pics if possible.

I've actually noticed twice on my 7AT there was a good 3 second delay after a U turn before the car accelerated hard

This transmission has taken a ton of getting use to after two CVT on the AUDI and HYUNDAI

Were you in manual mode before the U-turn, and in the right gear? Was VDC on maybe? My transmission never has a 3 second delay, that's huge. 3 seconds is like, time to eat a burger while you're waiting or something.

I used to have a delay when I was making a turn in 2nd. Especially if the turn leads to an incline.
However, I notice that this does not happen to me anymore after I had my car tuned.

No, prior to later that night I HAVE NEVER USED MANUAL MODE

No lights On

It's very odd

If you're not using manual mode, eh, who knows what gear you were in or when it decides to downshift for you. It's hard to complain about D-mode much. The car can't predict, only you can. Put it in M-mode and ride the revs down into the corner and downshift to keep them in the happy range (downshift as you're braking and you should already be in the right gear to accelerate out when the time comes).

"No lights on" I assume means nothing unusual on the dash, and you did have VDC engaged (the default on startup). VDC will interfere with any aggressive U-turn attempt...

ETA: However, I take no responsibility for you listening to me and wrecking. It's up to you to drive the car correctly

I originally Read over the VDC and my brain thought CEL for some odd reason

And no I've never switched that off either

Unfortunately haven't had the opportunity to play around in M mode

I'm just saying, there's a lot of missing data there on some of these reports. It may not actually be the transmission's fault

I press Gas pEdal, it no go

I understand a relative delay for the car to downshift, but as previously stated, not long enough to eat this Cheeseburger
