The only thing I'd be concerned about is making sure that each side of the
engine (or each set of six cylinders) would receive the same amount of
fuel, being that the calculations and maps would be running seperate for
each set of six.  Though I am just tossing this into the wind, not based on
experience or fact or anything like that.

The ECM I would recommend is the one for the late 80's Grand National, or
coincidentally, the 3.8L FWD Regals, LeSabres, and Park Avenues.  The ECMs
are the same... I've just started digging into the ECM, and because of the
GN aftermarket, there are TONS of aftermarket chips, injectors, PROM
reprogramming software, and the GN list is a super, super resources for a
lot of this stuff.  I even manged to shove a GN fillet crank into my FWD
block, based on the information I recieved from that list.
