    Yamaha F225 ECU Upgrade

    I believe you are saying that the harness will need to be swapped out; however, I'm not convinced of this because @boscoe99 said that my dad's -30 ECU was superseded by these later models. This means the pinout must be the same for the newer ECUs to plug into and work with a -50 harness. Since...

    Yamaha F225 ECU Upgrade

    @boscoe99 If I want to upgrade to a -31 or later ECU, would I also need to change to a -51 wire harness, or will his -50 work with later ECUs?

    My dad is older (heck, I'm older my dad is really older) and cannot hear the alarm. He often goes out by himself, but when I went out with him a few weeks back (for the first time) there was an alarm going off. Not only did he not hear it, but (presumably) he had been driving it like that for...

    It looks like the Thanks for this very useful info! So, to upgrade to a -31 or later ECU, would I also need to change to a -51 wire harness?

    Yes, that makes perfect sense. Thank you for the assistance! The engine is a September 2004 build (2005 model year) F225TXRD. Does this answer your question? It's all I have with me at the moment, but I do have a pic of a label showing a 69J-X-1018... number (the rest of the number is cut off...

    This certainly seems to be the case! When I say temperature data is being seen on the Yamaha Command Link gauge, there isn't an exact value. Instead it has the circle that moves from low/left to high/right at the bottom (under the large RPM value). It starts out on the left and moves to the...

    I saw this too and the Raymarine unit is using data from this PGN because field 2 of this group is oil pressure, field 5 is voltage, field 6 is fuel rate, field 7 is engine hours, field 11 control the check engine light, and all of these are working perfectly. Field 4 is the engine temperature...

    Yamaha F225 ECU Upgrade

    Without doing a deep dive into the documentation, I don’t know why temp wasn’t available in NMEA until 2006. Could be they took temp off a different bus prior to 2006. Could be temp wasn’t added to the gateway until 2006 and you just need a different or updated gateway It appears as though the...

    Yamaha F225 ECU Upgrade

    I saw this somewhere online which is why I thought about replacing the ECU with a 2006 or later one. Any idea if this would fix it? Also, why is the Command Link gauge able to read the temp but not the chartplotter?

    Yamaha F225 ECU Upgrade

    It's a Raymarine e127 and I've been all through the setup screens and still can't figure it out. Since his gauge is Command Link (Yamaha's version of NMEA 2000) and it can 'read' the temperature, it tells me that the data is on the bus. However, I'm thinking they might be using a proprietary PID...

    Yamaha F225 ECU Upgrade

    Helping my dad with an '05 F225TXRD. Can get oil pressure and RPM on the chartplotter via NMEA2000 bus, but no temp readings. He has a round Command Link gauge that shows everything, including temp, but how do we get temp to appear on the chartplotter? His ECU is a 69J-8591A-30-00 unit, do we...
