People who are more familiar with the 747 can probably
answer better than I, but...

If you are running closed-loop at idle, you'd probably
have an easier time tuning it yourself if you forced
open loop running there and shot for about 5-6% CO as
your target (assuming you can get the car to a CO
sniffer somewhere while you manipulate the idle bin).

For cruise, I would tend to suggest running lean of
stoich with a fair amoung of EGR and timing advance,
if you can make that happen.  This should give you
best economy at cruise, assuming you are not worried
about emissions.
