INDIVIDUAL CYLINDER TIMING

Each cylinder can be retarded up to 10° in 0.1° increments. Adjustments are made through the CylDeg

menu. Default for each cylinder is 0°. A Cam Sync signal for cylinder number one must be incorpo-

rated. The MSD Fiber Optic Pickup, PN 7555, is the easiest or a pickup kit could be fabricated on the

cam gear (MSD Kit PN 2346).

The spark sequence, or ﬁring order needs to be considered when selecting the ICT. You can go

through the Cylinder Numbers and place them with the corresponding position, or go to the Sequence

window and select from the pre-programmed ﬁring orders.

Spark Sequence Program the ﬁring order of your engine.

Degree Program the amount of retard of each cylinder. These retard rates are

added to any other retards that are active. Max retard is 30°.

Sequence Select a ﬁring order:

RPM/TIME ACTIVATION SWITCH

This program lets you activate a circuit by supplying ground on the Brown/White wire (up to 3 Amps

continuous). This can be activated in two ways; RPM or Time.

RPM Window: Program an rpm value to activate and deactivate a circuit from 800 – 12,500

rpm in 100 rpm increments.

RPM On: Rpm that the circuit is activated

RPM Off: Rpm that the circuit is deactivated

RPM Hysterisis: Built in Hysterisis allows the deactivation point to be set lower than the

activation value.

Time Based: Program an activation point in 0.01 second increments after the launch. Up to 25 sec-

onds of total time. The timer begins when the Dark Blue wire is removed from 12 volts and only if the

programmed Launch Rev Limit rpm has been acheived on the starting line.

OnDelay: The amount of time after launch (12 volts removed from the Dark Blue wire).

OnTime: The amount of time that the switch stays activated. This can be programmed from

0-25 seconds. It will always deactivate after 25 seconds.
