Marcell, could you please have this trigger bench tested?

Hi Jörgen.

Is that also with HALL-dirac filtering? vemscfg or vemslog ?

We could reproduce the problem with invalid setup only:

* VR trigger (~50 usec pulses after LM1815)

* and HALL-dirac filtering enabled; Note that validate warned about it.

With proper HALL signal, max 24 teeth (and signal stable for min 25% after the chosen edge), we could not reproduce the missing spark. It behaved well in all tests so far.

Note2:

*If we disable hall-dirac filter in primary trigger settings the ignition seems good.

* Can you disable HALL-dirac filtering and see if the occasionally missing spark goes away ?

* what is the duty % of the primtrig HALL signal ? (eg. 20% high 80% low ? )

* Erik do you use Hall-dirac filter too?
