B.5 Summary Table
The list that follows shows the different types of output configurations that may be employed.
Note that in some cases, an Extra Driver Box is needed to provide sufficient driver power.
“Standard” fuel injection is multipoint, staged or batch fire. DF is for Direct Fire.

* Although strictly there is no distributor on a 1 cylinder engine, selecting Direct Fire will
cause the E6X to wait for a Home signal.
** This configuration could also be used for waste-spark direct fire ignition.
B.6 Rotary Engines
The ECU is capable of providing fuel and spark to twin-rotor Wankel engines. The leading
and trailing sparks are generated separately, with a programmable ignition split time. The split
is programmed through the Rotary Trailing Map.
There are two ranges to the Rotary Trailing 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.
