I have 3:73 gears. I called Ford with my vin number and he told me it was 3:73. I will do a few runs in it today and let you know the outcome. Thanks for all the help guys

 

Not sure what kind of phone you have, but if it is Android, get this app: https://play.google.com/store/apps/d...edometer&hl=en

Perfect for checking your speed and has a HUD plus..it's free

 

Ok...put my GPS in my truck. Its 2mph off.. Tuner will say 80, GPS says 78. But man that really gets on my nerves lol. I want it to be dead on. But oh well at least I know its not way off.

I will check on that app Ryanwagner. I do have a android

 

Reset your tire size, add about 5 points to whatever you were using.

 

Yeah, if you can get it. Outstanding and VERY accurate.

 

App is very good. Works like a charm.

I will reset my tire profile tomorrow.

Thanks for all the help fellas

 

Woohoo.

 

Once you load the tune with a "customized" tire size, it stays there, UNLESS you reopen the "Custom Options menu". If you do that and go immediately to the Tire Size entry, it will load a "placeholder value" that is normally way too small. The key is to scroll to "Reload Previous Settings" IMMEDIATELY upon opening the Custom Options menu. Then, you can scroll to Tire Size and you'll find the value you set (almost). There will be a small difference in the value displayed because of internal rounding by the programmer. It is a difference you can ignore.

Thanks Jack. I knew it was some weird name that retained the settings but could not think it.

 

OK.. I have it within being 1mph. Set the value 2508 instead of 2510.

I thank all of you for all the help and ifo.

Have a great New Year
