I reflashed a E67 controller with tech 2 and it wiped out he serial number, I don't really care yet since I haven't licenced it! I just want to licence it so I can tune it! I pull PCM info the BCC and serial number fro the controller are all zeros, the BCC is ??? I tired licensing, and full flashing it, it says efi can write a new uquie serial number to it, if I full flash, so I tired to full flash, and it says the same error cannot license PCM, no serial number.
