Well i know there's a guy on the forums here that works for eurocharged and maybe he can confirm this , but do you know the location of the Chicago area one? There's no address ?
The main point if this post is the fact that i don't have a computer and from what I've read you have to set up an appointment and hook your computer to the car and they'll walk you through the process , if i understand correctly.
I'd like to avoid this if possible
