Good News guys !! About a month ago , knowing that I was looking at a 2 week business trip and would not be using my boat , I contacted my dealer about bring it in while I was gone ? It needed the 10 hour service (no biggie) , but I had the dreaded BCU error the previous two outing when turning the wheel full lock and shifting from forward to neutral / reverse which is also well documented on this forum , and the engine hours out of balance when operating throttles in sync mode. Both issues have been FIXED but I will only detail the engine hours on this thread. There IS a firmware update for Connex. It is version 39 and it works !! The only bad part is the dealers can not do it. The Connex must be removed from boat dash and sent to Kennesaw , Ga. They flash the unit and send back to the dealer. I was on the lake this past Wednesday and put it to the test. Got both engines exactly the same hours , down to the tenths , within 3 seconds of each other. Put both engines in neutral and activated throttle sync. Ran at 6000 RPMs (about 33mph) for 1 hour. Both engines showed exactly 1 hour more and changed tenths about 3 seconds apart. Well satisfied with the update.
This is great news. Thanks so much for sharing!

Is this still working correctly? Was GA able to correct the engine hours in the Connext to match actual Engine hours?

Yes , no issues with Connex since the unit was reflashed with the most recent firmware. Engine hours are the same and I have been running in throttle sync mode a lot since it was updated.

Was GA able to correct the engine hours in the Connext to match actual Engine hours? I had a Connext replacement at one point so my hours on the Connext are about 50hours shy of actual hours.

I was not aware or really concerned about matching the Connex engine hours to the "actual" engine hours ? The issue as I understood it was that when operating in throttle sync mode only one engine was registering hours in Connex. Other threads on this forum have members reporting big differences in port and starboard engine time on the Connex screen when they always start /stop engines together. The difference seemed to get bigger the more they operated in throttle sync mode.

Yes, what you explain is also my issue. I also had a Connext replacement at ~50Hr mark. These hours are missing from Connext, and now with the discrepency also between port and starboard, tracking actual hours has been painful.

Understood . While I'm satisfied the Connex issue has been resolved with latest update (#39) , pretty sure it does nothing to address the difference between real engine hours and Connex hours ? Sorry !

Both issues have been FIXED but I will only detail the engine hours on this thread. There IS a firmware update for Connex. It is version 39 and it works !!
Luckily I did not have the bcu problem. I do however use the throttle sync feature any time I kick it up on plane. My hours were definitely desync'ing and I dont think they were accumulating properly on either side as when my dealer pulled the hours from the ecu's, they were probably 4-7 hours higher at 96 each. Connext showed i believe 92/89 and some tenths.

Dealer told me they were able to apply v39 fw update but that they had to send the connext unit to yamaha to update the hours to match the motors.

Should be good to go! Great info here as usual! Thanks!

Mine is all repaired now. They had to get a new updated Connext from GA. GA programmed the actual motor hours in to it as well as v39. Then dealer installed it and now I am good to go. The sucky part was it took two weeks between reading motor hours and getting connext installed. That was two weeks without a boat. But in that time I installed 2nd bilge, new pissers, secondary fuse panel, SimRad, and trim tabs. So time was not wasted.

Another update. I have run the boat around about 20 hours more, and everything seems to be preforming as expected. I believe this fixed it for good.

I thought I read in at least one thread that you hold the SYS CONTROL button. Not sure all the years for which that would be valid and I haven't tried it myself yet. 🤞 I'm sure a more knowledgeable person than myself will be able to confirm this.

EDIT: Added src thread link.

Thanks tried the sys control but did not work. The gear icon worked. Or holding down the settings icon. Had an option for software. It looks like I have v37? Which does not have the hours fix right? I need v39

They put a yellow sticker on the back side (helm storage area) of mine when they updated. Sticker just has "39" hand written ? Might want to update your profile ? 2011 AR21 didn't have Connext.
