STEP RETARD

A retard can be activated by supplying 12 volts to the Pink wire (Figure 6). This is ideal for nitrous

applications or for a high speed retard. The amount of retard is set through the two rotary switches and

the total amount of retard is 30°. When the Mode Switch is in positions 4-7, there will be a one second

delay after 12 volts are removed from the Pink wire. In positions 0-3 the deactivation is instant.

RPM LIMITS

There are two adjustable Rev Limits, a Max Limit and a 2-Step. The Max Limit will protect your engine

in the event of driveline failure or missed shifts. This Max Limit DOES NOT override the limit set by

the factory ECU.

The 2-Step allows you to activate a lower rpm limit that is generally used on the starting line. When

12 volts are supplied to the Blue wire, the 2-Step is activated (Figure 7). When 12 volts are removed,

the Max Limit is active.

Both limits are adjusted with one dial in 1,000 rpm increments and one dial in 100 rpm increments.

When the Mode Switch is set in the 2, 3, 6 or 7 position, another 4,000 rpm will be added to the Max

rev limit value.

NOTE: The minimum rev limit is 2,000 rpm, even if lower numbers are selected.
