I have a 2005 Ford F150 that I purchased larger tires and I want to update the PCM using my Diablosport(U7151 rev 8r6) but I have looked in every menu and am unable to locate were to do this. The instructions I have says I should be able to do this. Please help.

RE: No tire size correction
you went into the modify tune menu and in all of the parameters listed there, there's nothing for tire size??

RE: No tire size correction
You should definitely have that feature in your tool. It should be in the modified parameter section. If you need help finding this, feel free to give us a call on the tech line.
No, i don't work here.
RE: No tire size correction
I went back and doulble checked the options in the "Modify Parameters" section but no Tire Size setting. It shows Axle Ratio, Idle RPM, Mass air table, Rev speed limits, shift point, shift pressure, spark advance and WOT fuel.
RE: No tire size correction
check in Axle Ratio

RE: No tire size correction
Yeah, look in "axle ratio" as tire size is sometimes located in this menu. Thanks Lew

johnp - do you know your new tire size's correct value for their Tire revs per mile??
from a previous post by Phil:
"Get a measurement from the ground to the top of the tires in inches. Divide the number 20168 by the measurement you come up with. Example: 20168 divided by 26 inch tall tire=775. so, 775 would be the number you would enter for the tire revs per mile."
