Fuel Flow Gauge


Well... an in-line fuel sensor would need to be added if my engines aren't NMEA 2000 - At least that's what I believe.

If my engines are NMEA 2000 compliant - which I think means that they would also have a NMEA 2000 connection point - then I wouldn't need a seperate fuel flow sensor (Garmin GLS 10 for example).

Still researching as I have not heard back from my dealer yet.

You're right though... the NMEA 2000 network seems like a very easy install.
 
SPICE,
THE WAY TO GO IS TO GET THE INFO FROM THE ECM, NOT FROM SENSORS. I FEEL THAT THIS INFO WOULD BE CLOSE TO PERFECT. SENSORS HAVE CLOSE TOLERANCES, BUT ARE NOT AS GOOD AS THE ECM.
 
Here's the answer I got from my dealer... who had to check directly with Volvo:

"There is no NMEA2000 on these engines. There is J1939 and they would need to purchase an aftermarket converter to convert CAN to NMEA."

If I search the Volvo site I see that the following year's 8.1 GXi (GXi-G or GXi-GF... mine are GXi-FF) engines have NMEA 2000. Missed it by one year. :mad:

I get that connecting the fuel flow monitor feature (on the Raymarine C80 for example) directly up to the J1939 connection point on the engines is the best way to go, but I have no idea how to go about this. This is why I haven't just given in and went with Floscan - I want to avoid that if possible.

Now I need to begin researching how to connect up my J1939 compliant engines with the C80.

And the games continues...
 
Maybe I am just completely way off base here... I search the Volvo Engine Database and find my engines (8.1 GXi-FF) and then do a search within the Operator's Manual for both 'NMEA 2000' and 'J1939' and get nothing back from the search results.

Perhaps my entire premise is mistaken and there is no such thing as a NMEA 2000 or J1939 connection point on these (or possibly any??) engines.

I'll keep digging but I'm a bit annoyed with all the "lack of information" regarding this subject. Nobody (dealer, Volvo, mechanics, etc...) seems to be able to give me a definitive answer as to whether this is even possible. The documentation at both Raymarine and Garmin leads me to believe it is, but Volvo doesn't mention it anywhere that I can find - even though they tell me my engines are J1939 compatible and that I need a converter from CAN to NMEA. If there is such a thing... how do I make the initial connectin to the engines?

Getting frustrated, but I'll continue to search.
 
SPICE, READ DIRECTIONS BUT CANNOT FIND HOW IT TIES TO THE ENGINES ECM? I HAVE NO PLUG HANGING ANYWHERE. DOES IT REPLACE A BLANK CAP ON THE SIDE OF THE ECM?
 
Not sure either. I did post this situation on BoaterEd (different user name for me ;)) and I see that you responded there as well. Thinking someone there might know for sure.

I'm thinking it plugs right into the diagnostic connection using one of these cables: http://www.blueheronmarine.com/Detail.bok?no=6312 at top of page.

But not entirely sure. I won't have access to my boat for 2 more weeks so won't know for sure until then. I did pose the question to my dealership and they are researching further for me.

If I can do this without adding a fuel flow sensor I consider it a big win. It might not be any cheaper but I think the display will be better. I may be asking for too much, but we'll see...
