E.3 Tacho Output Triggering
The F10X can be triggered by the signal found on the Tacho output of many aftermarket
Ignition systems, such a MSD, Jacobs & Crane. The Tacho output must be used if the ignition
system used is a Capacitive Discharged Ignition system with the multiple spark discharge.
The Tacho Output wire must be connected to “Negative Coil/Tacho Output” input, which is
Pin 36 on the F10X ECU. Please make sure that in the Trigger Setup page, the Trigger Type
is set to Coil Negative if this type of trigger is to be used.
Below shows how the Tacho Output trigger wire should be connected.
