If the SyTy code follows the same pattern as the Fiero 1&2 bar code,
then the VE tables only cover a one bar range.  They are indexed by a
fake 1 bar sensor value.  Thus the heading of 100 really does mean
100KPa.  Fuel delivery under boost is controlled by YetAnother table.

In the Fiero code, the only table of consequence indexed by the true
range of the MAP sensor is the main timing table.
