749 or 730 as aux fueler

[thergen at svn.net]

One issue that may or may not be a concern is that the auxilary ECM won't
be able correct open loop WOT fueling based on learning during actual
closed loop operation.  I'm assuming the aux ECM won't be run closed loop
at some point.  However, I'm sure there are people on the list who could
make the ECMs do anything they want at or near WOT.
