[Gmecm] Fuel Economy

The output of WB O2 units varies, but there are circuits 
(one op amp) to generate a simulated NB signal.  The 
Aussie WB unit has one.  These could be shifted to center 
around a slightly lean point instead of S.  The WB signal 
may be a bit slower resonse than the NB, and I haven't 
personally run one of these in a closed loop EFI.
