INTERLACED INPUTS (AND OUTPUTS)

The INTERLACED operation is specified on the global (F4) screen. It assumes that the RPM per firing is measured over TWO input trigger points. This is normally the case with a 4 cylinder wasted spark ignition signal, which looks like :

INTERLACED INPUTS AND OUTPUTS

 

Therefore, the interlaced operations mode is the same as specifying :

TEETH PER FIRING : 0.5


This is not possible, of course. However, the following results in the same RPM indication :

 

TEETH PER FIRING : 2   INTERLACED : 1
TEETH PER FIRING : 1    INTERLACED : 0


The interlaced mode applies to a 4 cylinder wasted spark output modification!
Other applications were not envisaged.

 

If the advance.retard of the two ignition signals is required, then mode = 12 must be specified.
