4.5.3.1 Coolant Temperature Correction
The coolant temperature correction map is accessed through the menu structure and can be
found in the maps menu.
The coolant temperature correction map is used to adjust the fuelling based on the coolant
temperature measured by the ECU. The map has 32 bars distributed across coolant
temperature in the range of –40°C to 127°C and each bar represents a percentage correction to
the current calculated fuel.
4.5.3.2 Air Temperature Correction
The air temperature correction map is accessed through the menu structure and can be found
in the maps menu.
The air temperature correction map is used to adjust the fuelling 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 fuel.
4.5.3.3 Battery Voltage Correction
The battery voltage correction map is accessed through the menu structure and can be found
in the maps menu.
The battery voltage correction map is used to adjust the fuelling based on the battery voltage
measured by the ECU. The map has 32 bars distributed across battery voltage in the range 8V
to 16V and each bar represents an addition correction to the current calculated fuel. The
battery voltage correction is applied after all other corrections take place.
4.5.3.4 Fuel Priming Map
The primer map is accessed through the menu structure and can be found in the maps menu.
The primer map is used to add a quantity of fuel based on coolant temperature when the first
trigger is detected 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 set quantity of fuel injected prior to and
independent of any other injection event. The primer injection will only inject fuel once on
the first trigger event.
4.5.3.5 Post Start Map
The post start correction map is accessed through the menu structure and can be found in the
maps menu.
The post start correction map is used to adjust the fuelling based on the time since the engine
was first started. The ECU has a time reference for the first 120s of engine operation. The
map has 16 bars distributed across time in the range 0s to “Post Start time Limit” (refer to
4.2.2 Fuel Set-up Page, p29) and each bar represents a percentage correction to the current
calculated fuel.
4.5.3.6 Barometric Pressure Map
The barometric pressure correction map is accessed through the menu structure and can be
found 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.
