I'm trying to write my tune to a new ecm I got from PCI Conversion (they think the original they sold me is bad) and I keep getting "unlicensed vehicle" when I try to write it. The window to license a new vehicle does not pop up. In the troubleshooting section is says that "unlicensed vehicle" means that the vehicle is not supported. Its a e38 ecm, how can it not be supported? Am I missing something here?
