Gas Pedal Delay

cfleming2226 · 06-10-2010, 03:28 PM

Has anyone experienced a brief (about 3 - 5 sec) delay from the time you push down on the gas (floored it) to the time you actually accelerate?

I was out the other day about to merge (Honda with a tin can exhaust next to me) so I floored it to jump ahead of him and there was a good 3 sec delay ... really disappointed. Especially because in my head I was gonna own this guy, but by the time I accelerated I had to slow back down to let him in!

I get the same thing, which is why I gradually press harder, instead of just flooring it... The delay is kind of an annoyance... Apparently the computer's reaction time from signal input to throttle response is not at the speed my mind wants it at lol.

I guess as long as its not a problem with the car I will adjust ... i just really get a kick when it tosses me back in my seat, and with I can make "racers" look silly!

Thanks for the responce!

just be careful...don't want to draw unnecessary attention to your car

I notice you are in an auto, I'm guessing you aren't in manual mode at the time? It probably just isn't downshifting when you want it to. I have that happen sometimes, but usually it adapts pretty quickly to your current driving style. Or just switch to manual when you want to boogie down.

Try turning the VDC off. VDC may be delaying the throttle response to prevent the tires from slipping. But once you turn it off, have fun crashing into a curb.

The world of emission and drive by wire, the computer opens the throttle gently rather than snapping the plates open for emission purposes. I have been saying that the 370 feels like it has less throttle response than my 350, I am starting to think I am right

It is actually faster in AT to floor it. since if you want to floor it in MT you need to put the gearbox in manual and then down shift to the right gear.

while in the AT mode you just SLAM your foot down and it instantly shifts to the lowest possible gear.

I never had this kind of delay other than the gearbox shifting

isn't that only if you did it in regular D mode, if you were using the paddles (which i would imagine you would be if you were flooring it), it'd be the same.

I actually merged yesterday, and after i was at speed i realized i didn't even remember downshifting before i floored it (which i most certainly did)

any way to fix this problem?

Mike · 06-11-2010, 06:16 PM

Yes it's fixable through tuning to have the throttle open quickly rather than delayed.

Kyle@STILLEN · 06-11-2010, 06:28 PM

I have never used this personally but I have heard good reviews on it...One of the reviews came from one of our engineers who tried it out on his wife's BMW...

Not sure if it was adding the nst pulleys or the up rev tune but no delay anymore.

m4a1mustang · 06-11-2010, 06:56 PM

Shouldn't a tune take car of this? I get this too when I try to go from a low rpm in first or second gear... the car falls flat on its face before surging forward.

You can recalibrate the throttle tables on your ECU to make your throttle response faster.

I did that, the car is alive now, and feels like a real sport car.
