Gas pedal

[DenaliDrive]

Hey y'all,

Is it there anyway to adjust the pressure of the gas pedal? It doesn't require much pressure, which results in movement while going over rough roads. Car & Driver review had the same issue when first tested.

what year/make/model are you talking about?

Moved you here for more focused answers. Post up your year - make - model so we know what you're working on.

My ‘03 is like this as well. It’s a bit annoying, especially considering how loud my exhaust is with these PRC heads, but I just live with it. Not a big deal.

That one is drive by wire. There isn't really a way to increase the feed back - the pedal spring is all internal. Maybe a newer replacement may have better built in feel

depends, 03 was a year that some have a cable and some do not I don't know the specific range though. same for clutch fans/electric.
then in 04/05 (i think) the alternator pins changed on some 4pin/2pin
this is all based on member feedback of what they have or had
my 03 was drive by wire... clutch fan 4 pin alternator
the wifes previous 04 had a clutch fan and 4 pin alternator
then her 05 had electric fans and a 2 pin alternator
there are some mixed with all of the above pretty much

you might be able to get the throttle response tuned how you like with a tune like @BlackBearPerf not sure how much they could smooth it out.

Thanks for the information, guess I'll try and use cruise as much as possible

I have HP tuners... my truck is a cable which is what I bought HP tuners for...

There is a page of calibrations for the throttle by wire. My C5 vette has throttle by wire and works AWESOME. It is definitely a better system than the cable IMO. Sorry to hear yours is too sensative.

My '03 Denali is the same way. IIRC everyone's is. Very springy gas pedal. You just kinda get used to it after awhile.

Pedal commander and set it to eco mode?

They don't make 'em for our generation of trucks

My Corvette was professionally tuned... He reconfigured all the throttle by wire stuff. It works SO awesome. I'm tuning my Tahoe by myself but I don't have the electronic throttle on the Tahoe.

Here's an idea of what settings are in the computer for your electronic throttle. I'd venture you could dial back the sensitivity. Although, it says modify at your own risk, but I'd think a tuner out there might know all that figures out better than I.

FYI ~ There are two modules on these older setups (not sure about new stuff). The first is the PCM. The second is the throttle controller / computer.

There's tuners in most major cities. Maybe somebody on the forum here knows of a reputable one in your town who could dial back the the throttle sensativity?

I don't think the problem is that the throttle is too sensitive, it's the physical spring on the gas pedal. There's no "dampening" or whatever. Causes it to be springy/bouncy. Especially when going over bumps or rough road. Your foot keeps bouncing the gas pedal. Think of it like a car with blown out shocks. Bounces over the bumps. I've gotten used to it though and kind of figured out how to keep my foot steady.
