Your battery is probably too low. This has happened to me on my 14 GT.. I usually just jump it with my truck then it writes perfectly. Now I make it a habit to start and let it run for 10 minutes then shut it off to flash.
I 100% would not have done the write entire though...
@blackbolt22 thanks for the response,tried that out and got it working, what?s the deal with write entire?
Not sure what you mean.Quote:

Glad I could help. I was so worried when that first happened to me... The deal is it's easier to recover from a failed write cal than a failed write entire. Something I have wondered though is if I wanted to return to 100% stock like from the dealership or do I need to write entire?Quote:

write cal only is faster than write entire on fords, its literally the only reason we added it. Fords don't suffer from the majority of recovery issues GM's and other makes do so that really isn't the reasoning behind it. Mainly just for speed.
Well that?s clears it up for me there @[email protected] much
