problem with efi live
BYW this is a friends cable. I'm wanting to data log so we can tune it later. Is the cable married to a certain computer?
You need to install the drivers for the cable.
If the cable can be seen with the software, you can tell that by going to HELP in the software then v1 or v2 licensing, it will show you the cable specs.
If you can see that and still no connection, Check your cigarette lighter fuse.
