I already have a VEMS V3.8 ECU with auditrigger/camhall inverter (suitable for VR/VR and VR/auditrigger)

Installing Audi 4.2 Liter V8 ABH code engine.

The engine has Auditrigger (every 2nd sectrig VR pulse masked by cam-HALL) like Audi AAN.

c272: 272 teeth on full engine cycle, so 34 tooth between events:

Can this trigger setting work?

Will check your annotated vemslog.

Triggerlog hint:

Please publish triggerlog (obviously that is the way to proceed during trigger setup (even when it goes smooth without issue).

When capturing triggerlog, if configured for auditrigger, some pulses might be hided.
