    Hi Tomas

    Contact your regional distributor for a copy.  It is available if you are an instrument developer, you have to request it.

    Hi Tomas,


    were you able to get your hands on the CAN protocol? I'm trying to convert data so I can use it with older EFIS that I have and that is not compatible with the ECU unit.

    In talks with the USA distributor they say it is available to any instrument manufacturer.  You would need to contact your Rotax distributor and sign an NDA to get copy is what I was told.

    Out of curiosity, do they release the only EFIS CANBUS protocol under NDA?  Or does that include the maintenance port CANBUS protocol as well?  The EFIS protocol is not difficult to figure out without the documentation.. maintenance port is similar, but they flip message bits to obfuscate the information.
