Distributor for Rotation and Phase Reading:
The distributor timing requires a distributor equipped with a Hall sensor. If the simultaneous or semi-
sequential injection strategy is used, all of the distributor teeth can be the same size. For the sequential injection
strategy, it is necessary for the distributor to have one of the teeth smaller than the others in order to identify the
cylinder 1. If the distributor is symmetrical and the user wishes to use these strategies, it is possible to remove the
first half of the tooth referring to cylinder 1 , for identification of phase in this tooth.
Distributor only for phase reading:
In this case, use a hall distributor with only one tooth. The teeth (or windows) of the distributor should be
removed, leaving only one (as shown below).
Camshaft Position Sensor for Phase Reading:
When using a phase sensor in the camshaft, make sure that the size of the tooth in the camshaft is
approximately one and a half times the width of the sensor pole.
