I just purchased the cables (Audi) to connect to my ECU and am not being successful at getting a connection. I can see the USB to OBD2 listed as a device connected through a com port. I'm using Windows 10 for an OS. When I start Guzzidiag it finds the comm port but when I execute the connect command and switch the ignition on it tells me that the ignition switch is off.
I have one more question: I just installed Power Commander IIIUSB and it connects fine with my PC. Can I do does PCIIIUSB have the capability to do everything Guzzidiag can do?
