BLACK BETTY12

SO I know that a tune done before will leave a code in the computer even when it has been returned back to stock. I am wondering do all tuners do this or is there certian ones that will erase the code? I have an SCT 3015. Thanks in advance

I wasn't aware of a tune leaving a CODE in the PCM. Where'd you hear that?

The 2011+ pcm for mustangs has a tattle-tale area. No longer can you disconnect the battery to clear the history. It's not a code so much as a "permanent record"

yea chris from AM was on a thread and said that exact same thing about the 2011's. I dont think there is any real reason to put ur car back to stock when u go to the dealer but I guess some dealers are a bit ridiculous when it comes to aftermarket. Luckily for me mine is not

Is it a binary counter that counts the times it has been flashed?
