The leading and trailing sparks are generated separately, with a programmable ignition split
time. The split is programmed through the Rotary Trailing Split Map.
There are two ranges to the Rotary Trailing Split Map, below 2000 rpm and above 2000 rpm.
This map is a measure of split, or delay, from the leading spark, which is computed from the
base ignition map normally with all corrections. The map indexes split against the engine
load. When displayed on the Engine Data Page, or in Data logs, the trailing spark timing is
shown as an absolute advance in degrees BTDC.
If using a distributor, there are two ignition outputs, one for the leading and one for the
trailing coils.
If using direct fire, the two leading sparks are fired together, as in a waste-spark set-up. Two
individual coils must be used for the trailing sparks, as these are fired separately.
If using direct fire, a Home signal is needed for trailing ignition to be generated.
