Need some help.
Went to move my Edge CTS from my 01 Expedition to my 2010 Expedition, both supported by Edge. When I connected to the 10 it showed it did not recognize or support the program in the ECM, and called for an update. Updated and tried again with same result. Now I am wondering if the previous owner had a tuner or had the ECM flashed by a tuner. Is there anyway to determine this short of taking it to the dealer?
