According to Roger, "the BUDS diagnostic program can be downloaded from the Rotax website, but to make it functional you will need a $800-1200 dongle".
Why the need for a dongle? Could you not connect your ECU through a 9-pin D-sub connector directly to your laptop running BUDS? And does anyone care to comment why Skytek in a recently published 912iS installation (http://www.zenith.aero/video/rotax-912is-installation-explained) put two 9-pin D-Sub serial ports on the panel? Do you really need two separate ports for Lane A and B of the ECU?
Some clarification would be appreciated.
