The problem was the E38 and E67 DMA PIDs are prefixed with E38 and E67 respectively. Black Box Logging was adding the prefix GM in the *.efi files. When the *.tun files were loaded into the scanner, it could not find (for example) the PID GM.AFRATIO_DMA because the PID is actually called E38.AFRATIO_DMA.
If you really need the data from those log files, you can edit the *.efi files using Hexedit (from
www.bpsoft.com). Change the GM.xxxxxx_M PID names to E38.xxxxxx_M names. In Hexedit that will require you to insert a character after the GM. I.e change the existing "GM" prefix to "E3" and then insert an "8" to make the prefix "E38".
