E120 Fuel Used

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Travis,

Unlike the current MFD designs supporting LightHouse II software (i.e. Raymarine's a/c/e/eS/gS-Series MFDs), earlier MFD designs did not include trip fuel usage calculations which would result in an estimated fuel remaining data being displayed by the MFD. Instead, the software of the earlier MFD designs simply repeated data found within PGN 127497 - Engine Trip Parameters. I suspect that should a NMEA 2000 analyzer (ex. Actisense NGT-1 & PC w/NMEA Reader software, etc.) be interfaced to your SeaTalkng / NMEA 2000 backbone, you will find that this PGN is not among the PGNs transmitted by your engine system's NMEA 2000 gateway.
