I want to tune my car and gain mad hp!! Anyone have a link to a good kkl vag com cable? What kind of laptop charger will I need to connect to my battery? I have so many questions and this place looks like a great place to learn.
It is a good place to learn. A cable link is in a pinned post in the noob questions.
Your laptop should be fully charged when flashing, or on a charger on the mains. Likewise, the car should be on a charger on the mains.
