Quick question here.
I would like to purchase a Superchips Micro Tuner for my '01 F150 5.4 Ltr. 4X4. However, I need to know if it will work if I have already had the dealer "mess" with the programming?

I put Larger tires on my truck, then went to have it reprogrammed by a mechanic friend of mine at Ford. Well, Ford doesnt HAVE any programs that coincide with my particular tire size!! Soooo... we guesstimated what it "should" be and used those settings.

Will a Micro Tuner be able to overlook this little problem? Or will it be confused by the strange program?

Any answers would be appreciated.

Thank you

 

The dealer should have put one of these stickers under the hood somewhere. If they didn’t you have to have the dealer read the new PCM code.

 

Thats the same tag the dealer put on under my hood after the factory reflash.....

 

Thanks for feedback! But there is no sticker like that anywhere.
Do I need that number for a Micro Tuner to work? Is that something Troyer would need before shipping to me? I guess my question is: "why do I need this number?"

Thanks again!

 

The Superchips Micro tuner has all the Ford codes already programmed in the unit but if you’re going to get a custom tune, (Xcalibrator) you need your PCM code. The advantage of a custom tune is that it is specifically tuned for your PCM code and will give you approximately 50% more HP than the Superchips Micro tuner

Hi DSN46,

What these guys are talking about is a complete "reflash" - where you go into the dealer and they update your PCM to a new code. That's what the picture of that sticker is all about, it reflects the new software revision that was loaded into the PCM - in this case, it was on a 2004 F-150, and wasn't written in very neatly by the mechanic that did the work - but it was very nice of John to post that picture so everyone could see it.

I don't think that's what happened in your case on that 2001 - I think they just attempted a speedo calibration via the VID block, in which case we can simply use your vehicle's original computer code for the custom tune. (All they can do at a dealership is to alter the speedo for a gear ratio or tire size that was offered by the factory on that vehicle, that model year, by the way.)

Anyway - Here's a link to our instructions on how to locate your vehicle's computer code: http://www.troyerperformance.com/cgi...&link=compcode

Now you only need that computer code if you go with our *custom* tuning - and that is what I highly recommend, as you will get 50% larger power gains compared to what the standard Superchips #1715 Micro Tuner will provide for your truck.

Whether you order our custom tuning, or simply use the 1715 Micro Tuner, it will save a copy of your stock factory tune, and then upload the performance tuning - so whatever the dealership did will not be in effect when you are using the performance tuning. We can correct the speedo for you either in our custom tuning, or the 1715 Micro Tuner can do it by you simply telling it the installed tire height - it's instructions will tell you all about how to do that.

However, like I said - I strongly suggest that you go with our custom tuning, as that is what will actually get you the best results in terms of raw power, performance improvement, driveability, and virtually every other aspect of powertrain operations.

Feel free to call us if you have any questions on this, & best of luck whatever you decide!

 

Thanks Mike and everyone else who posted!!
I now know what needs to be done. Man I love this board!
I'll be calling Mike soon I'm sure.
