Disconnect the battery for 10 minutes and hook it back up.

I just bought my 03 stang and the person that had it before me programmed the ECU. If i disconnect the battery and keep the key turned will that get rid of the programming

so you know..your computer will go retarded...and at first will run like ****..bc ur computer forgets everything and doesnt know how to run properly...it will take some driving for it to re learn itself

i was told i needed to do this or buy a new ECUbecause i am getting 373's installed and they said they can't program it because i don't know what the last person used and how they programmed it. Is that correct?

if you just get a tuner youll be fine..thats the point of the tuner to reprogram the computer..therfor erasing previous tunes and that..u would be like writing over whatever is on there..and entering what u need.
