INSTALLATION INSTRUCTIONS

ADVANCE

This is a Gear Shift Advance feature that is designed to advance the timing (or remove any retards)

during a shift to keep the combustion chamber temperatures consistent.

Note: To advance the timing, the crank trigger must be advanced. Therefore, all other timing func-

tions must compensate for this advance.

Gear: Select the number of gears.

DRpm: Program the rpm drop that indicates a gear change from 200-1,500 rpm.

Deg: The amount of timing that is advanced. This is determined by how much

retard is active. You cannot program more advance than the current amount of retard.

Sec: The amount of time that the advance is active. Adjustable in .01 second

increments from 0-1.5 seconds.

Note: The Step Wire Gear Select program overrides the RPM Drop value for shifts.

CYLINDER COUNT

CylCnt: This is the number of cylinders of the engine. Programmable for 4, 6, 8 and Odd fire

6-cylinders (90°/150° only). Once a change has been made, turn the ignition Off and On to

reset.

Tach Trigger: There are two choices for the output of the tach terminal on the end panel of

the ignition or the Gray wire of the 12-pin connector. The output is a 30° duration 12 volt signal

that is compatible with most tachs and data acquisition systems. The default is

Trigger which

provides the most accurate signal for rpm sensing components. The

Timing program should

only be used when spark timing data is required by an acquisition control or to fire another

ignition.

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. This will help by listing the cylinder number next

to the sequence number.

Spark Sequence

Program the firing order of your engine, reference only.

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°.
