Its not that anyone is saying YOUR truck is not working correctly...All thats being said is that there's benefits to be had by doing this procedure. However it wont work on vehicles that arent "drive by wire" Whats funny is that there are tons of people doing this and returning very happy with the results....But some are just too stubborn to even take 5 seconds out of their life to benefit from its results Their loss.

Its already been said, this is a legit procedure to reset the TPS....which apparently is beneficial for a lot of our trucks. But what does anyone else, beside "all knowing" you, know.

AGAIN, this is only effective on vehicles that are drive by wire, not ones with a throttle cable....It would be dumb to try this on a throttle cable driven vehicle...

 

That is why I haven't done this on my F150, 4.6 V8. It apparently screwed up his engine somehow as he says that he tried the Calibration method. It wouldn't run correctly afterwards. I am just guessing but I think it messed up his TPS. First thing I would do, though is unhook the battery for about 30 minutes and see if that resets everything.
If not, then it's time to start troubleshooting.

A bit of a rant: It was previously stated that this is a well known calibration method that works. BUT, there was no proof provided in the form of documentation or links pointing in that direction. That alone just irritates the hell out of me. I am not going to do or try something just because someone says "Try this! It works!" End of Rant.....

With all of that said, I do appreciate the disclaimer that this doesn't work on cable operated EFI systems.

Sorry Bro but I dont have the specific proof that you are looking for, So if you dont want to try it then dont... I didnt see anywhere in this thread stating anyone MUST try it..
Why is everyone on this thread crying like little girls? If you dont want to try this little tip then dont... go to the next thread topic and add your 2 cents there.. No one is twisting your arm to do this or trying to sell you anything..

 

i did this and did not notice if it did any thing for the down **** when passing but it sure did help off the line response thank for the post and have a good day all!

 

I did the process while sitting in the drive in window at the bank, waiting on the tube. My truck was already very responsive, with the custom tune and I really can"t say it helped any. If it did, it was only slightly. I will add, if doing this messes anything up, you already had a problem and it just had not yet made itself known.

 

 

Okay.

I'm going to go on record here as the 2nd guy who has doubts about this alleged 'recalibration'. I'm going to actually agree with Steve83 (always a first time )

I just logged these inputs. Before and after, there were no changes in any of the related values at all - suggesting that no data points were modified within the PCM either.

You folks need to read this: http://articles.d-tips.com/art8.html

And then you'll understand why this is not going to benefit a ETC vehicle - the PCM is already doing this sanity check - and redundantly. (There are actually THREE APPS sensors ( on the pedal) and the TPS device mounted on the TB).

Finally - I did my own 'blind taste test' with my neighbour - new Siverado - (and a bona-fide POS - sorry, TMC, lol). I showed him the procedure and offered to do it for him. When I was done (and I did not actually perform any of the steps) he was astounded by the change in throttle response. And - he was resoundingly pissed when I revealed the truth - cost me a few placating brewskies, that did, lol.

This goes a long way in explaining why my GP hands out calcium pills to cure all manner of patients' afflictions - the Placebo Effect is a powerful tool.

Sorry to be the 'mythbuster' here.

BTW - y'all DO know that the source of this info -F150Forum - is also the source for Shotgunz' best humour, right?

Y'all will get a bigger hit by just disconnecting the battery and do a KAM reset - clearing Adaptive is always good for some added 'git-me-up' (while it lasts).

Don't get bent fellas - just offering a different perspective - and some impartial data & observations.

Nope. The PCM constantly adapts to the TPS's range of motion, without any toe-tapping. Ford engineers thought of this in the mid-80s, and it's standard programming now. Did you read the post JUST before yours? It was a guy with a throttle cable endorsing this procedure because he observed such a dramatic change. Now you've burst his bubble. It's a public forum. Anyone can post in any thread, with or without your permission. If you didn't want comments (some positive; some negative), you should have posted on your own private forum.No wonder it's so cold! Survey say...

Whether its the placebo effect or not.. My truck always seems to run better right after I wash it.. I guess there will always be someone that will challenge a method if there isnt concrete proof that it works.. Either way, It seemed to work for me and makes me feel better about myself.....

 

Read the bottom section of this caption. It applies to all Ford cable-operated throttles since ~'87, but electronic throttles are even smarter:

Yeah: Archimedes, Magellan, Columbus, Einstein, Tesla, Ford... They were all such doubters! Why couldn't they all have just accepted other people's explanations?

 

Both great posts! While opposing, I can appreciate both views. Hey the placebo is powerful effect and hey, if calcium pills help the nausea from my chemotherapy treatment, than who can really bash it?

Is this throttle mod placebo? Very well could be and I wouldn't be surprised if it is. Is it making people happier about their vehicles at no expense or invested time? I would say that it is. Now if I were charging 3easy payments of $39.99 to do this then I would say that was a problem. But it's free and takes 30seconds to do. So whether it works or not via tested results is not important IMO. But if those who try it are even a little pleased with it then I see no harm done. It's not like it promised an extra 30HP. I mean who is this hurting and why would anyone get so up in arms about it NOT working. If it doesn't work, then what have you truly lost?

It's all good though. I'm thankful for an open forum where there is the sharing of different thoughts, ideas, and experiences.

 

I tried it on mine and it didn't do squat. However, I'm not going to try to stop anyone from trying it.

 

You have the wrong year to do it. 2004-2010 is the only years it will work on, you have a throttle cable not drive by wire like the new body style 04 and up have. I went out and tried it on my truck, I'll know the results after I get in it to leave today

 

Using some of the reasoning in this thread...Where is the cold hard facts that this in fact does nothing? I want proof from those ******* on it that it in fact does nothing

I'm not arguing whether this is legit or not. Im arguing against those who were so fast to jump on peoples' cases saying it was voodoo when there were people who have tried it and felt an improvement. Fact of the matter... it costs nothing to do, try it for yourself before you jump to conclusions and start belittling people simply because you feel you are smarter than others. As Bluejay already stated, if your truck had issues after trying this it wasnt due to this, especially if you had issues after trying this with a throttle cable driven truck. There's no way pushing your gas pedal down a few times could possibly screw up your engine.

MGDfan, thank you! Someone actually took some time to check this out for himself and did a bit of research before going on a rant!

F150forum.com gets made fun of on here, but in all honesty there are far less egotistic self righteous ****** over there. I enjoy the info here, but rarely post due to that one reason.

 

Well, I was all prepared for the truck to start fish tailing similar to what my drag truck on nitrous does. Didn't happen.
