Running 1 tooth per cylinder
In situations where there is 1 tooth per cylinder in a cam cycle you can select either “one tooth per cylinder” or a value equal to the number of cylinders in the “No of teeth per cam cycle” parameter. A sync sensor is not required if a single ignition coil with a distributor is used because the ECU will fire the ignition output once per trigger signal and the distributor will distribute the ignition to the correct cylinder. However, If you need to run coil-on-plug ignition then you must use a sync sensor on the cam. The trigger tooth directly after the sync sensor tooth is the index tooth and is usually positioned in front of the trigger sensor when the engine is somewhere between TDC and 15 deg BTDC on cylinder number 1.
