Accelerator pedal calibration?
One thing I still find really annoying with my 06 350 (5.4) is low speed throttle control control. It's just about impossible to move from stopped to very slowly and smoothly. No response , no response, no response.. then a surge. Backing up to a trailer really sucks. Yesterday I was trying to back up just enough to get my lowered tailgate over a low cement wall, the last six inches to go the thing took off and slammed the hitch into the wall. Good thing the hitch was there, but I still felt like an idiot.
So, I'm about to take it to the dealer, but before I do..
I hear hints about an accelerator peal calibration procedure for the fly-by-wire units, and I've searched for anything like this, but I've not been able to locate anything concrete. Is this real? Does anyone have a documented procedure or a link for this?

I do it on my 05 with 5.4L. You turn the key to the run position. Let the dash gauges stabilize. Then slow and steadaly push the accelerator pedal all the way to the floor. Then let up on the pedal, and turn the key to off. You can now restart the truck.

Thanks Brewster.. I'll be sure to mention it to the dealer if I need to go to them... Did you have the PO455 code, or just the surging?

It was on a thread on the F150 side. I would do it on my 04 F150, every once in a while. It is a know service procedure for Fords. Your teaching the limits of travel, for the accel by wire.

Does this really work on the Super Duty? I have always thought there was little response from the accelerator pedal but belived it to be the 6.0 PSD in the low RPMs.

If it has accel by wire, I would think that it would work. The computer has to know its range of motion, including the lower & upper stops. This is so the computer knows what position the pedal is at, when being depressed.

This is great if it works. I recently added a bunch of sound deadening material to my truck and now the pedal won't go down as far as it used to. I have to really stomp on it to compress the sound deadening and get it to go far enough to shift into passing gear. Hopefully doing these steps can recalibrate the pedal to make it so I don't have to press down as far to get full throttle. I'll try it when I leave work tonight and post back on here.
