INSTALLATION INSTRUCTIONS
STEP RETARDS
There is a single step retard that is controlled
through the Pink activation wire or through rpm.
It can also have an rpm point that the engine must
reach before the retard becomes active (a minimum
rpm can also be programmed that must be reached
before a step becomes active). A time based ramp
can be programmed to gradually bring the retard
to its full On amount, or to ramp the retard amount
out (back to no retard) from its setting.
Activation through Wiring: The retard is
activated when 12 volts are applied to the
Pink wire. The maximum retard allowed by the
ignition is a total of 30° (including other retard
amounts or a boost map).

Activation through RPM: The step retard can
also be activated through rpm. In order to achieve
this, 12 volts must still be applied to the Pink wire,
and an rpm value must be selected from the Step
RPM menu. When 12 volts are applied, the retard
will not activate until the rpm value is reached. Note
that the retard will remain active above this rpm.
It will deactivate when the rpm drops below the
set amount or when 12 volts are removed from
the Pink wire.
Note:
If you prefer to activate the step retard through
the activation wire and not rpm, then the rpm
value of the retard step menu must be set
to 800 rpm.

over a time based program (Figure 12). It is
adjustable from 0-2.5 seconds in 0.01 second increments. Default is zero for both On and Off.
RPM: The minimum engine rpm that must be reached before a step retard is activated.
On: The amount of time it takes for the step retard to reach its Retard Degree. Allows a gradual
ramp On time to reach the Retard Degree. User adjustable from 0.00 to 2.50 sec. (0.01 sec.
increments).
Off: The amount of time it takes for the step to retard to reach NO retard. Allows a gradual ramp
Off time to reach NO Retard. User adjustable from 0.00 to 2.50 sec. (0.01 sec. increments).
Deg: The amount of retard.
Note: All of the retard amounts are cumulative and the maximum amount of retard is 30°.
