Does the Dominator let you set dwell when using a distributor and TFI module? This would be on the SPOUT signal. Nominally it's a 50% duty cycle.

The early (Gray) TFI modules compute dwell on their own. The leading edge of the SPOUT signal controls when the spark fires. The falling edge is ignored.

The later (Black) modules are referred to as CCD, for computer controlled dwell, where the rising edge of the SPOUT signal fires the spark, and the trailing edge is the start of dwell.
