5.3.4.6 Barometric Pressure Map
The barometric pressure correction map is accessed through the menu structure and can be
found under “Fuel Correction Maps” in the maps menu.
The barometric pressure correction map is used to adjust the fuelling based on the barometric
pressure measured by the ECU. The map has 32 bars distributed across barometric pressure
in the range 523mBar to 1046mBar and each bar represents a percentage correction to the
current calculated fuel.
5.3.4.7 Gas Pressure Map
The gas pressure correction map is accessed through the menu structure and can be found
under “Fuel Correction Maps” in the maps menu.
The gas pressure correction map is used to adjust the fuelling based on the gas pressure
measured by the ECU. The map has 32 bars distributed across gas pressure in the range 0Bar
to 12 Bar and each bar represents a percentage correction to the current calculated fuel.
5.3.4.8 Gas Temperature Map
The gas temperature correction map is accessed through the menu structure and can be found
under “Fuel Correction Maps” in the maps menu.
The gas temperature correction map is used to adjust the fuelling based on the gas temperature
measured by the ECU. The map has 32 bars distributed across gas temperature in the range
–40°C to 127°C and each bar represents a percentage correction to the current calculated fuel.
NOTE:
The gas correction maps are designed to be used with gas injection systems are
are normally not used unless gas injection has been employed.
5.3.5 Ignition Correction Maps
The following is an explanation of maps that are used to correct the base ignition timing based
on the environmental conditions.
5.3.5.1 Coolant Temperature Correction
The coolant temperature correction map is accessed through the menu structure and can be
found under “Ignition Correction Maps” in the maps menu.
The coolant temperature correction map is used to adjust the ignition timing based on the
coolant temperature measured by the ECU. The map has 32 bars distributed across coolant
temperature in the range –40°C to 127°C and each bar represents a percentage correction to
the current calculated ignition angle.
5.3.5.2 Air Temperature Correction
The air temperature correction map is accessed through the menu structure and can be found
under “Ignition Correction Maps” in the maps menu.
The air temperature correction map is used to adjust the ignition timing based on the air
temperature measured by the ECU. The map has 32 bars distributed across air temperature in
the range –40°C to 127°C and each bar represents a percentage correction to the current
calculated ignition angle.
