To recalibrate your speedometer after changing tire sizes:
Start with 20186, divide by actual tire size in inches.
Divide again by 66.66.
Example:
20186 / 31 = 651.16
651.16 / 66.66 = 9.77 (rounded up)
Thus for 31" tires, the calibration number is 977.
To set the calibration, ground the single wire connector under the glove box (often Lt. Blue wire w/ a Yellow tracer, but you might want to check a manual for specifics), hold in Reset button on trip meter and turn ignition to ON. After the speedometer needle cycles from zero to top speed and back to zero, press Reset button again. You should now see the calibration # that you currently have. From here, use Select to get proper calibration, and press Reset to store.
When you press Select, the number only goes down, but don't worry if you need a higher number. After you reach a certain number (400 or 500 I believe), it will start back at the highest number the speedo can be calibrated with (often 1100), and go down again.
Notes:
Larger tires will require a smaller calibration number.
If your new calibration number needs to be larger than the highest number allowed, just go with the highest number allowed.
If you shut your ignition switch OFF before you press Reset to store the new calibration number, the number will remain what it was before you started.
With stock 235-75 15's, the calibration number should be about 1044, but you may find that it's been set at 972 from the factory. This means that your odometer has more miles on it than you have truthfully traveled.
WARNING:
You can only change the calibration number 6 times without replacing the module.

i had no idea you can do that!!!!
mine says 972. but i put 31's on so its pretty close. but i didnt ground it so i guess thats why i couldn't change it.
when you first turn it on it says "E8 06" whats that mean? and when you push select on the first screen it displays "1111111.." then "2222.." and so on. whats that mean?

It means using a jumper wire to connect the wire in question to ground.

The numbers you saw are simply there to test the digits on your digital odometer.
The reason you couldn't change yours is because you didn't ground the enable wire. You can check your calibration code without grounding the wire, but you have to ground it to make any changes.

Just for future reference: I have a pet peeve about being "called out" in the subject of a thread, or even in the text of the thread. I don't want to be the subject of a thread in a technical forum, and naming someone in a subject line can only REDUCE the number of other users who read the thread & post info to it. So I actively discourage it by ignoring any thread with someone's name in the subject (especially MY name) for at least a day - usually 2 or more. Just ask your question - anyone who can help you will post. Stating that you only want one user's opinion not only discourages anyone from helping you in the future; it also makes it seem like you're depending on & expecting the person you named to do all the work of helping you. That's not gonna happen, so there's no point in asking for one person. By posting to a public BBS, you have access to a whole WORLD of knowledgeable people, so don't limit your options.
Another of my pet peeves is a subject line that DOESN'T contain the subject of the thread, but that's self-explanatory.
Anyway, back ON-topic:
Everything you never wanted to know about the PSOM ('92-96 speedometer) is described in this thread, which incidentally is linked in another thread here on F150online.com. You'd have found it if you had searched, so I recommend doing that first next time you have a question.
