I set a non factory tune on my 2011 mustang gt and lost the tuner. I would like to retune my computer. However my new tuner does not support overwriting non factory tunes. What is recommended?

Okay, this forum says "just go to autozone" to reset the ECU`~ http://www.allfordmustangs.com/forums/2011-mustang-talk/348178-how-do- you-reset-ecu-2011-gt.html

what a cop-out~

would the lost contraption have done this feat? get another one like it! this is not a hard drive your messing with, its tickling your prom it is. ill never under stand how something from china can make an American car run stronger ,maybe im missing something?

your computer must be returned to stock before you go any farther. it must be reflashed. autozone or any other parts store cannot reflash your computer. you have 2 options. 1-go to the dealership and have them reflash your computer, or 2-contact the company that made the original programmer and see if they have a way to do it. worst case, you send them your computer and your VIN and they reflash it for you. i have had to have this done for customers before that lost their programmers.

Madmopar is right. Take it to the dealer maybe they will only charge you an hour to do it. Hopefully where ever you are located the hourly rate is less than 100
