Car is Porsche 944 Turbo, 2.5litre inline-4 with K26 Turbo. It has 132+1 auditrigger (without cam sync).

Ordered twin-shield harness for 6cyl from webshop (to have boost controller outputs etc) and VEMS with full auditrigger (2x VR+ 1x HALL . With or without camhall inverter ?)

Would like to add cam sync to the engine.

Where should the cam sync event take place with auditrigger configuration?

See InputTrigger/AudiTrigger (examine the concept and scopeshots)

If no sectrig seen in the triggerlog, than This will show if camHALL inverter is present or not. If no sectrig either way, doublecheck the crankhome-VR signal.
