place for a given PFI channel. A firing window is created around each PFI channel, specified by a firing

simultaneously, the firing window must not be greater than a span of one engine cycle.

The TDC reference for the window is the TDCX value associated with the applicable PFI channel.
PFI_Firing_Window_End: Defines the end of the window in Degrees Before Top Dead Center (DBTDC).
The TDC reference for the window is the TDCX value associated with the applicable PFI channel.
