"...Beyond All Recognition"

One of Matt's sites

I picked this up on a thread over at Dodgetalk.com.  Here it is in one shot without the back/forth discussion to refine the technique:

What To Do

1. With the engine off, get in the car and shut the door.
    
2. Turn the key to the right, to its furthest point without actually starting the car.  All of the idiot lights will go off, beeps will sound etc.
    
3. Wait for the beeps to subside and you are left only with the battery warning light.
    
4. Pretend you are racing your daughter's boyfriend's fartmaster-equipped ricer and stomp the pedal to the floor.
    
5. While keeping the pedal mashed, slide your foot to the left so it is on the left edge of the pedal, and then in one quick motion move your foot left so you completely release the pedal in an instant and it snaps back up on its own. Elapsed time for the mash-slide-release motion should be a few seconds (reportedly a count of 5 is a magical number). The instant you hear the pedal complete its snap-back motion, turn the key quickly to the left so the vehicle is shut off, taking care not to get so caught up in the rush to do it fast that you twist the key off in the housing.

What It Does

Throttle response should improve pretty dramatically over a truly stock computer.  When I first did it I had just completed a battery disconnect/wait20/reconnect to completely reset the vehicle's computer (I forget exactly why now).  The speed at which the vehicle shifted gears was very sluggish.  After doing the reset the car snapped from one gear to another so fast I was woo-hoo'ing out loud inside of the car.

If you drive consistently like a nut, the car will probably stay this way.  However thats pretty unlikely, and you will notice the vehicle slowly easing itself back to sanity after you have been driving around town for awhile.  Repeating the above procedure should set you back to snappy shifting again.

Origins

Thiis is just forum scuttlebutt, but apparently this technique has been known and used for some time in Mercedes automobiles.  The "D" in "DC" should then explain how this managed to find its way into a Dodge.

Why Does This Work?

Beats me, but if I were to guess I would say that we are giving the computer an input that it has the time to process, and cutting off that input before it has the chance to fully complete whatever calculation is in progress. Or it could really be the grownup equivalent of a video game cheat code.

Gouranga!
