DIGITAL E-CURVE FUNCTIONS

RPM LIMIT

This distributor is equipped with an adjustable rev limiter. It

is adjustable from 5,000 - 10,000 rpm by a rotary dial under

the cap and rotor (Figure 1). The rpm will not exceed your

selected amount to protect the engine from over-rev damage.

TIMING FUNCTIONS

Electronic Advance Curve Operation: The Electronic Advance Curve is managed by a

microprocessor built into the ignition module. You can program an electronic timing advance curve

by adjusting two rotary switches under the distributor cap (Figure 1). A magnetic pickup is used

as a trigger device that tells the ignition module when to fire the coil. The pickup is triggered by

a reluctor mounted to the distributor shaft. This means that you have to set the distributor at the

highest, or Total, amount of advance that you want to achieve (including vacuum advance) and

compensate with one of the selectable ignition curves (shown on page 4). Following are important

definitions that will be used to set up your timing.
