All I want to do is swap out my halogens for the xenons and re flash it. Just making sure I can do it myself with the BMW scanner 1.4 or will I have to get the dealer to do it. I currently have a shark tune on it and wanted to make sure the flash did not affect that. I am just not familiar with the flash process as far as if you can choose what gets flashed or if its a complete rewrite of the ecm.
