Assuming you have plugged in the appropriate constants for your engine's
displacement and injectors, then yes the shape of the WOT VE table will
closely resemble the shape of the WOT torque curve.  You might want to aim
for 80% VE at peak torque, just to give yourself some headroom to play
around in.

To get close,  just use a ratio factor.  50 MAP would lead you to a VE of
50% of the WOT VE table value, at that engine speed.  You should be able to
start to tune with  such a Map.



Have Fun;
