This is where the big question comes into play. Will the ECM of these 1997 502 MPI engines put out data for NMEA 2000??
If not what protocol are they on? Is there a converter for these to put out display data of the engine info?
I can not find info, so far, that addresses this direction I am thinking to go.
What do you all know about this?
