Jamie, i can give you more info and format/sample .dbc files if you require for the convertor...i've written some for the PLM's we use with CAN on ATI, also many other things.....it as as ElectronSpeed says, the .dbc format is auto-industry wide pseudo-std for can message templates...CAN database file. Allows comms with any CAN device using common format.
Happy to provide some samples...your local mazda turbo man
