Fuel Tuning
The Fuel Tuning node configures the main Fuel System information for the engine.
Fuel
Tuning Method
Sets the method for fueling calculation. Most installations will use Volumetric Efficiency. See also Fuel Base.Auto V.E Air Temp Compensation
When Tuning Method is Volumetric Efficiency and this option is enabled, Intake Air Temperature is used as part of the VE fuel calculation.Fuel Type
The type of fuel being delivered to the engine.Percentage of Ethanol
Only available when Fuel Type is set to 'Ethanol Petrol Blend'. This is for delivery of a known mixture of an ethanol/petrol blend when no Fuel Composition sensor is being used. Eg, you will only ever use drum 'Race' E85 whos Ethanol Content will never change.Fuel Load Type
Sets the source for the 'Fuel - Load' channel.Fuel Pressure Input Type
Sets the relationship of fuel pressure to the manifold pressure. Most installations will use a MAP Reference fuel pressure, however many OEM systems may have a Constant fuel pressure. This setting calculates the 'Fuel Pressure Expected' channel, and generates the 'Injector Differential Pressure' channel if no fuel pressure sensor is present.Base Fuel Pressure
Sets this to the base pressure of the fuel system. The base pressure should be checked when the engine is not running. Under certain circumstances, this setting will calculate the Injector Differential Pressure and Fuel Pressure Expected channels.Enable Flood Clear Mode
Enables the flood clear system that disables injection output when the throttle position is above the user demand max and the engine is below the cranking RPM.
Conditional Base Tables
Cranking Fuel Amount
Enables a Cranking Fuel Amount table that is used for fuel delivery when the engine is under cranking RPM.Zero Demand Fuel Amount
Enables a Zero Demand Fuel table that is used for fuel delivery when the user demand value is less than the user demand minimum.MAP Reference at Zero Demand
Only available when 'Zero Demand Fuel Amount' is enabled. This is the load value used as part of the output of the Zero Demand Fuel Amount table.
Functions
O2 Control
Enables the Closed-loop O2 Control system. See 'O2 Control' for more information.Transient Throttle
Enables the Transient Throttle system. See 'Transient Throttle' for more information.Prime Pulse
Enables the Prime Pulse function. See 'Prime Pulse' for more information.

The idle mixture is very sensitive to changes in injection time. Idle injection times are usually around 1.5 to 2.5 ms. If the injection time at idle is much lower than this, it may become difficult to set accurate idle and cruise air/fuel ratios. ...
