5.3.2.4 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
crank 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 crank trigger event.
5.3.2.5 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, p36) and each bar represents a percentage correction to the current
calculated fuel.
5.3.2.6 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.
5.3.2.7 Gas Pressure Map
The gas pressure correction map is accessed through the menu structure and can be found 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.
5.3.2.8 Gas Temperature Map
The gas temperature correction map is accessed through the menu structure and can be found
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.
They are normally not used unless gas injection has been employed.
