Eddie, the 747.ecu file contains (AFAIK) everything that the list knows
about the '747.  It's true that not all the tables are known, but enough
are that it can be set up for most any engine.  There is plenty to be
discovered still in the prom image, only a small percentage of all the
data space is figured out.
