Common engine signals
Typical networked engine data can include RPM, coolant temperature, oil pressure, engine hours, alternator or battery voltage and warning status. Some systems can also provide fuel rate, throttle position, load-related values or propulsion-specific information.
Not every signal is standardized the same way
Manufacturers often maintain proprietary data alongside standardized NMEA 2000 messages. A multifunction display may receive information through a manufacturer gateway that another device cannot access without the same interface. Model year and firmware also matter.
Why data quality matters
For performance analysis, a signal must be reliable, time-aligned and understood. A fuel-rate value with slow updates or uncertain units can create misleading conclusions. SmartTrim treats network data as a measured input that needs validation rather than assuming every field is equally trustworthy.
How this supports SmartTrim
Logger can align supported engine data with motion and GPS. Prop can use those aligned signals to add operating context to a propeller test. Controller development can use validated engine and vessel data to improve state estimation while still maintaining local sensing as a core layer.
