Configure the volume to duration conversion for direct injection.
None (Main library). (See Section 2.3, “Licensed Features”.)
The pan_InjectorCompConfig_DI block configures the fuel rail pressure (FRP) analogue input used to convert injection volume requests into units of time. As described in Section 6.5.2, “Direct injection” just prior to each direct injection pulse is made, the fuel rail pressure analogue input is sampled. Any volume request is converted to a duration using a 2D lookup map. This technique compensates for rapid variation in the fuel rail pressure that may occur after the injection schedule is requested by the application.
A drop-down selection of analogue input channels to use as the fuel rail pressure input.

Fuel rail pressure transfer function - volts axis
This is the X-axis of the transfer function that converts the fuel rail pressure sensor voltage into engineering units of MegaPascals (MPa). The voltages contained within this axis should range between zero and the voltage specified with the Fuel rail pressure maximum voltage parameter.

Fuel rail pressure transfer function - pressure
This is the Z-data of the transfer function that converts the fuel rail pressure sensor voltage into engineering units of MegaPascals (MPa).

Fuel rail pressure maximum voltage
This is the maximum voltage that can be read by the chosen analogue input Channel before the input saturates, e.g., will be 5.0 on a 0-5v input. This allows the ECU to convert a raw number of A/D converter counts into a voltage.
