Modifying Mechanical Advance Distributor
The following steps outline the necessary steps to modify a mechanical advance distributor for use with
the AEM Infinity EMS. Of particular importance is identifying the correct tooth on the eight tooth reluctor
wheel that is to become the single pulse cam trigger once all other teeth have been removed in order to
achieve proper ignition sync and rotor phasing. The distributor will be set up in a way that the cam pulse
occurs 90° before TDC for cylinder #1. These instructions must be closely followed if the supplied base
sessions are to be used.
Step 1
Identify terminal #1 on the distributor cap as if the distributor were installed in the engine. Distributor is to
be installed into the engine so that the cap hold down hardware is crosswise with the engine (dashed
lined) with the cam sensor wires exiting on the even-cylinders side of the engine. Terminal #1 is the
terminal that points towards cylinder #1 (arrow).
