I bought my Livewire from American Muscle and I could not get it to read the strategy on my car. Since I am friends with my dealer I told him what I was doing and the problem and had him check my OBD port but no problems. I called American Muscle yesterday around noon and explained the problem. They said they would send a new one and shipping tag for the old one. 3pm today I had it installed and driving. That's pretty good service in my opinion. Highly recommend them and thanks to Dan in the tuning department for his help.
