4.5.3 PFI Tab
The PFI tab is for configuring both EPT and TMP operating modes for the PFI channels of the PFI Driver module.
The EPT and TMP injection pulse command sequences support one pulse and apply it to all four PFI channels
of the module. The individual channel enable buttons, operating mode, and current profile parameters for the PFI
Driver module are configured via the PFI and LS Driver Setup window. When the EPT Mode is selected in the PFI
Module Control tab of the PFI and LS Driver Setup , the TMP parameters of this tab are not applicable. When TMP
Mode is selected in the PFI Module Control tab of the PFI and LS Driver Setup , the EPT parameters of this tab are
not applicable. The lowside driver channels of the PFI Driver module do not have the ability to be operated engine-
synchronously and are not configured from this tab (refer to PFI and LS Driver Setup window). The PFI Driver
module is an optional module for DI Driver Systems and this tab is not applicable when the module is not present.
EPT Pulse Enable
Tip Strip: Enables injection pulse
Detail: When ON , the EPT Mode command to the PFI Driver module will be active for the specified duration.
When OFF , the command will be inactive, but the specified timing and duration will still be implemented.
Therefore, the timing of the adjacent pulses will remain the same whether the pulse is
ON
or
OFF
.
Timing
Tip Strip: Start Of Injection angle with respect to TDC
Units: DBTDC
Detail: Specifies the Start of Injection (SOI) timing in Degrees before TDC.
