Have seen lots of mixed info here. Most says that you need a scan tool or etc. I have a USB OBDII adapter that I use on my F150 to make edits that are necessary. What does it take to do the same with a RAM. Mainly the TPMS values that I want to change. In Nashville, Indiana if that helps.

 

What software are you using for your ford?

 

Forscan

 

Did you have to pay for that??

So far, the only reliable software I am aware of is the HPTuners stuff. (link over there on the right) Keep in mind, it is not inexpensive......
