ive been using this same file for a while now just tweaking things here and there and now all of a sudden it wont complete when i try to flash it in???? in the tune software it says "ok to flash" yet when i go to the scan and tune software and open the same file i noticed its has ~~~~~~ by ECM model where as my original base file has a model number. the other weird thing is ALL my tune files that werent originally from my truck (diff OS but all base files i got from other members on here) they all have the same ~~~~~ under ECM model??? i dont get what could all of a sudden do this and i dont remember if they always had ~~~~~ or an actual ECM model number. and what i dont get is WHY they dont????
