Gas Pedal Sensitivity

[Power Hungry]

What he's referring to is how aggressive of the throttle pedal is at light throttle. We used to get similar complaints from the diesel folks. This is a phenomena that is often associated with Drive-by-Wire systems. Since there is no direct relationship between the accelerator pedal (APP) and the throttle plate, there is a transfer map that takes the linear voltage from the pedal and applies a logarithmic curve to the output for the throttle actuator.

One of the more common modifications is to make the curve a little more aggressive to help improve throttle response. Once in a while, we get a little too aggressive in the light throttle portion and what you end up with is a "touchy" throttle.

This does NOT affect the shifting since those work on the actual voltage signal from the a APP. Those issues are usually caused by mis-adjusted shift strategies.

I'm looking into the throttle problem and will have an answer sometime in the morning.

Take care.

Anything yet?

Sorry about that. Just got back from a dyno event in Tennessee.

Give me a shout in the morning and we'll get your update online.

If it makes a difference, I went back to stock tune and the touchiness/sensitivity is still there but much, much less drastic. I have a vague recollection of adjusting a few values in the custom power programming settings, so I could have brought this upon myself.

Let me know how/where to get this update.

I noticed how touchy my throttle is, is there any more news on this?

I have kinda gotten use to it, but driving in gravel a lot, its hard not to make spin marks haha. Even my girlfriend drove my truck the other day and got out and was "I don't remember it being that hard to drive"
But when its back to stock it seems fine, but on level 2 and 3 I feel like I have to move the pedal a lot more to get a response and when I do it usually jumps.

Suprisingly my throttle is actually opposite. I felt no change over the stock setting. We discussed this in another thread and it has to do with my throttle body for some reason. I'm hoping that when I order my custom tunes Bill can make it a little more "touchy."

Do let us know how long it takes to regret that decision.

Bill, enjoy your hiatus, then come back and fix this!
