Gas Pedal Delay

juld0zer · 10-07-2016, 09:21 AM

ZeN,
Please refer to my earlier posts. I detailed exactly what you propose on doing. I have done it before and it works, and later on after a lot of research i went several steps further to restore a more consistent driving experience.

In short, the 370Z really suffers from heatsoaked intake air temperature sensor. All intake systems are affected. All your observations mirror mine so there is nothing 'wrong' with your car. It is doing everything as it is programmed to do. There is a solution but it's not for those who love to show off their engine bays - although it's definitely a conversation starter. Goodluck & happy modding!

HI,

I have the same issues when it gets hot outside, my 370z turns into a Nissan Sentra.....Bogged down lethargic acceleration and laggy throttle response from idle up to about 3500RPM.

Did anyone come up with an ECU fix for this?

Has anyone approached Nissan to do a software update on the car or at least the ECU?

When i reflashed a different throttle map using Uprev, it cured it. Aside from the heatsoak issues but you need to determine which you have - heatsoak lag or the actual unrelated lag for no reason

This is definitely limp mode. I was having similar issues when I went to 3" MAF housings. Check to make sure there aren't any soft codes sitting in the background on your ECU. I've experienced limp mode multiple times with no CEL but the soft code was present in the background when I scanned it. Sometimes those soft codes can come and go if the problem is intermittent so scan the car often and maybe you can catch it. FYI between 2009 and 2014 Nissan used a P006A code (MAF/MAP to throttle position correlation) which came up often, even on factory stock cars. In later ROMs Nissan removed it because it was too problematic.

Side note: the wstar's 2300 throttle map is pretty good. That's what I'm running currently.. could be a bit more aggressive at lower RPMs But it does get the TBs open much quicker than stock and is stable over all

Hello everyone, I guess for documenting purposes and to find out what else have folks discovered in the 4 years that have passed since this.

I have gathered that one way to help with this delay is a tune, the other delay has to do with heat soak of the IAT. Lastly for those boosted, issues with the booster MAP.

Throttle pedal commanders seem not be as efficient after a tune.

I have adjustable throttle response with my ecutek tune
