Fuel - MAP

Check the Fuel - MAP compensation table.

The fuel must be increased by 100% every 100 kPa increase in air pressure.

Normally the MAP table should contain the following values, with a straight
line increase between values.

0 kPa

100 kPa

200 kPa

300 kPa

400 kPa

500 kPa

-100 0 100 200 300 400

This table is equally applicable whether the MAP sensor is used for
barometric pressure measurement or for manifold pressure measurement.

Note that the higher pressure sites will only be available if a high pressure
MAP sensor is used.

Fuel - Cold Start

Start with the typical values listed in the help.

Fuel - Acceleration Enrichment

Start with the typical values listed in the help.

Generally acceleration enrichment is not required above 4000 RPM.

Other Fuel Compensation Tables

Typically all other compensation tables should be set to zero.

Ignition Tables

Ignition - Main Table

The table should be smooth.

Make sure that the Ignition - Main Table is initialised with a conservative curve
for the particular engine, not too advanced and not too retarded.
