hello all. i have been searching and searching on how to reset my edge to my tire size ( 305/55/20 ) and i am needing some help. does anyone know what to put into the edge for my tire size? i've looked in the book and everything and can't figure this out.

 

Here are the dimensions. The manual should tell you how to enter either circumference in mm or revs/mile.

 

Good morning sir!

Just to back Shotgunz up, did you happen to see the Sticky on the Gryphon ( Edge) at the top of this forum?

Here is the relevant post: https://www.f150online.com/forums/3949845-post3.html

And here is an excerpt from the Edge manual, page #20:

"Tire Size
The Evolution has the ability to correct for changes in tire size. If you have
changed your tires to a different size the PCM will miscalculate vehicle
speed which can affect shifting as well as the speedometer. Correcting the
tire size will allow the PCM to accurately calculate vehicle speed and
odometer readings. You will not need to change the value displayed if you
are running factory size tires. After choosing to set your tire size, the follow
screen appears:

The numbers on this screen represent the circumference (in mm) of your tire
size. The default value the Evolution displays is the current value stored in
the PCM. Adjust the tire size by pressing the [UP] and [DOWN] arrow keys. "

So - in the Custom Options screen, you would simpy enter the tire size, in 'mm', as per Shotgunz table (more accurate than the on in the manual).

It is quite straightforward - even for a Luddite like myself ( remembers when an Abacus was state-of-the-art ).

Good luck - I have faith in you. Believe in yerself!
