Today Rotax distributed a new service instruction, SI-912 i-018R3 where we shall check the software version of our ECU´s.

But where to find the new software file for the upgrade?

I know we need B.U.D.S. level 3 for this but we still need the software(firmware) file for the ECU.

    Hi Mikael

    Go to the Flyrotax.com web pages and go to technical documents.  You then look for your engine type and find the drop down list.  In that list you will find "software" and there is the file.  All the versions currently use the 4.0 software as you can see.  

    Cheers

    Does anyone know what changed with this new ECU software for the 912iS? 

    What does it fix and why bother with it if everything is running well? Is it really worth going out of my way to fly to my A&P to have him flash the new ECU software?

    Also is this something an A&P would automatically update during an annual, or only upon request from the aircraft owner?

    Mikael:

    I think you're asking about the actual firmware file that's loaded into the ECU.  That's probably only available to service centers and iRMTs who Rotax authorizes to do the update.  According to the SI, the update process requires a special BUDS adapter that's also not available except to those who are authorized by Rotax.

                                     

    Rotax Wizard:

    I have a 912iS Sport that has not yet been installed on my aircraft.  The table in the appendix to SI-912i-018R3 shows only one firmware version for that engine (Software Config P/N: 864082, File Name: 811-6566-130.ath, Status: latest).

    Some of the other engine types show an "outdated" software version, then a "latest" version on the next line.  Does this mean that there is no outdated version for my engine, and my ECU contains the current version from the factory?

    I'd like to avoid shipping my extremely expensive ECU to a service center just to confirm current software.  Surely the factory knows which software version they shipped in each engine's ECU...

    Engine serial number: 7705679

    Thanks.

    hi 912iSPower (?)

    I would recommend going to take training on the iS engines, they do have a special training for it.  The new software replaces all the old versions and even has a section so you can use it with the old 914 TCUs.  

    I doubt any A&P can upload the new software unless they have the dongle and know how to use it.  On an annual the injected engines are required to connect to see the fault codes as well as inspected and clear them.  A great many iS owners simply ignore that part however and just wait to get flashing or steady lane lamps before they look for any issues.  

    I note you show as being in Florida.  My best suggestion is to contact Lockwood Aviation in Sebring, they run an injected engine class regularly.  Dean is very knowledgeable and can help you I am sure. 

    Cheers

    Thank you, but it doesn't really any my question... what changed with the new ECU software? Do you know? Without know what's changed, it's hard to determine if it's actually worth going out of my way to flash the new software.
