I haven't yet purchased my OBDlink yet, but plan on it soon. I have a 2011 f350, with 3.55 gears, and 37x13.50x20 tires. Am I going to be able to get my Speedo adjusted to match GPS without codes? The dealer wanted $110 just to MAYBE adjust it! Thank you
If you select taller gears, 34s, and offset you should be close. I have 3.55s, set to 3.31 and 34s, it is pretty much spot on at 80mph for speedometer. Miles ticker is a bit slower by about 6% but I am okay with it
Edit, was thinking jeep 3.21s, ford has option of 3.31

So with that configuration for you, is that for 35's, or 37's that are on your truck? And no codes?
Forscan lets you change tire size or gear ratio as needed with no codes. I switched from the factory, rougher than heck 20's down to 18's off a 2017 and forescan took care of it with no issues.
Both ids and forscan can adjust the spedo but the options are factory tire sizes, and axle ratios. So unless you can manipulate the axle ratio and tire size i doubt youbwill get it accurate with 37"

There is a link on the last line of the tire size area ABCD. It is to a tire size converter page. I have seen where people have created sizes to accomplish accuracy. Keep in mind you will most likely set a P160A code. This code is set by a difference in BCM vs PCM that we can't write to yet.
It will take some patience but you can get it perfect.
I have found that on my 16 the speedo needle is slow no matter what I do.
Well no wonder it throws codes for oversized tires. Making you lie about gear ratios instead of designing it to be functional! It's not like it is something new they couldn't have designed into the software!

After re-reading what I typed, I am coming across like a ranting crazy person. I'd like to apologize for that! I am a new 6.7 owner, and I'm so used to the caveman 7.3, all of this is sort of overwhelming. I have done some reading on this thread, and seen how much work you guys have done on it. MUCH appreciated, and I will attempt to upload my files to contribute my info once I get my mx adapter.
I finally had time to use the latest edition of Forscan to enable the exhaust filter percentage screen with manual regen button . It works perfectly. I was looking at other items to mod and saw a temp,productivity screen and not sure what that is. I have a 2102 F-250 SB CC 6.7L build date 04/2012 i have attached my ford as built data from ford site and the 2016 F-250 sheet I found on this site to make the changes. I can add my saved as built data before any changes when I can figure out how to do that..Thanks to all those that work on the Forscan app and change lists.

Did I miss something or did I just misunderstand? Can you enable a manual regen option for one of the steering wheel or dash buttons, or does the manual regen still have to be done with Forscan?
