Trigger setup for Alfa 60 deg V6

trigger-wheel.png

(sounds like) an odd-fire engine with 60,180,60,180,60,180 spacing. That means 10 and 30 tooth between TDC-s (or reftooth, which is constant angle before TDC).

Primary trigger

Did you check VR sensor polarity by the simple wrench-test (with DVM DC mode) or InputTrigger/TriggerLog ?

Secondary trigger - camsync

** if it's HALL (or optical), you need to change a small jumper in HW, on the bottom of the PCB (simple, but might need to unclamp the box), see GenBoard/Manual/InputTriggerHardWare. You can ask for shipping the box unclamped, or the sectrig can be changed to either HALL or VR (as you request)... oops, you have the box already. Never mind, easy to setup, just find out and specify what type of signal you have.

If you have the jumper in sectrig=VR position, than you can only trigger sectrig by VR pulse(s) on EC18-pin12 (connecting only a HALL-sensor to EC36-pin13 will NOT work by itself, although the HALL signal (pulling the EC36pin13 to GND) can be used to "mask" (==gate) the VR pulses as done in InputTrigger/AudiTrigger.
