    For what it's worth, I did this procedure a year ago and followed the instructions exactly. After waiting an hour, I got in my car and started driving. I noticed a difference right away.

    Well I moved across country, literally. From the California desert to near the coast of Virginia. Not sure if the HUGE change in climate had anything to do with it but I have noticed my R/T AWD getting somewhat pokey.

    I did this procedure again today and again, after waiting an hour I noticed a difference straight away. More pep, smoother acceleration. Awesome.
    Is this short enough?

    Hey not to knock this down in any way, I'm just curious.

    Does anyone have an explanation\evidence that the duration of time from the "Up to Floor \ Floor to Up" and also the 1 hour wait time is necessary?
    I've done a similar process of TPS Calibration via a Power Commander on a motorcycle. Procedure: Key-On-Run position \ start with the throttle Closed (Click Set) \ then WOT (Click Set) and you're done.

    I realize this is not a motorcycle nor a power commander but I would presume we're calibrating the Min & Max values.
    I just can't understand (without explanation) why the "15 second" Up-Down-Up & 1 hour is needed.

    Planning to try this and figured additional info would be nice. Perhaps then add the informed response to the 1st post for other inquiring minds.
    Thank you, very much appreciated!

    I tested it. That is how it worked. You're not calibrating the "min/max" values. You are in fact calibrating the response between the pedal and the throttle body. Going slow and consistent over the 15 seconds allows for the throttle body to be taught to follow what you want it to do immediately when you want it to.

    You've tested multiple methods or the 1 original way that's listed?
    I don't see the correlation of how going slow and consistent teaches a vehicle's "memory or logic" to follow what we want the throttle to do on demand.
    That is unless you're giving the computer a more defined Min \ Max setting which I'm leaning more towards. (Though you mentioned it's not calibrating Min \ Max values)

    Example: The default\generic out of box 0-100% throttle settings have 1-20 points of calibration and\or acceleration settings. By more slowly pressing the throttle pedal (within reason) we're creating more like 1-25 or 1-50 points of calibration, thus providing a more sensitive pedal that reacts\instructs the ECU to spray more fuel, etc and so on. (1 being idle \ Highest being WOT)

    I believe that your method works (based on user feedback) I'm just one of those why and how people. Know what I mean?

    If I had a computer like the dealers do; I could give you all the facts to back up the "Procedure". I don't. I tried several ways and that was the way that worked. Just accept it for what it is. Sometimes faith is all you can go by.

    This really works. 2.0 SXT Caliber with CVT had a "dead spot" in the beginning, now it is gone. Also I thought that maybe I should change oil to cvt since it was working a little odd, like having "bumps" now and then and not working smooth. After this calibration bumps are gone. Acceleraters smoother and kickdown does not anymore have that odd delay. To have this much positive effetcs to cars behaviour usually costs hundreds and takes a lot of work. This was free and took five minutes of time. STUNNING!
