B.2 Ignition Output Configurations
The E6X ignition outputs can be fired differently, depending on the Spark mode, which can
be found in the Ignition Setup page.
B.2.1 Distributor Ignition
The simplest of ignition systems is the distributed setup. The distributor uses a rotor button
and cap to distribute the spark to the correct cylinder. In most cases the distributor will
contain a triggering device used to trigger an ECU or an ignition module directly.
On older engines, the ignition advance curve is formed by the rotation of the pickup for the
triggering device inside the distributor. This is achieved through a vacuum advance
mechanism and by centrifugal bob weights. To use this triggering device with the E6X, all
forms of ignition advance will need to be locked or removed, as the E6X requires a fixed
signal to operate properly.
Rotor phasing
A common problem that arises when distributors are used is cross-firing. This usually occurs
when the rotor button is not in the correct position when the ignition output is fired. To
correctly set up the distributors “Rotor Phasing” you will need to do the following:
Calculate the minimum and maximum timing requirements of the engine. For this example
we will use the following:
Minimum Timing 10° BTDC
Maximum Timing 40° BTDC
