NSS7 with Lowrance EP 10 fuel flow sensor

[Jhudds]

So i have the old version NSS7 and I installed a lowrance EP 10 fuel flow sensor that worked on my old boat which was a single inboard. So I bought a new boat (twin inboards) and installed my old NSS7 and fuel flow sensor and purchased another E60 sensor and installed. Now heres the issue I am having, I cant seem to get the simrad to display fuel left on board. I believe the issue is with the sensors and getting them set up correctly. When i check them in the settings panel in the network devices I see both of them, and while engine is running I can check the data and see both are reading gas flow independently, but they both show as port and one seems to have a different version software. Not sure why....I am confused as to how to set these up as there seems to be no information on setting up duals. I seem to be able to get fuel burn, but since they are not operating correctly I am unsure if they are reading correctly.

Anyone have any clues?
