Help needed on AudiTrigger secondary trigger hardware configuration

[msh]

So, I've audi 10v turbo engine, with it's stock AudiTrigger, controlled by self assembled V3.7 unit. The problem is - since information about AudiTrigger secondary trigger hardware is controversial, it seems that I've made a mistake with secondary trigger, so the question is, which of the two are correct approach:

1) Output of secondary trigger converter chip is pulled down by transistor so that ECU can receive signal only when cam hall sees the magnet
2) output of converter chip is undisturbed, but cam hall, through cam hall inverter, is connected to separate ECU input and "audi cam hall scope" enabled in configuration, so ECU ignores secondary trigger signals when cam hall doesn't see magnet.

Do I guess right and second is the correct approach?

I do not think Audi hall scope working in latest firmwares.
Use 1st.

However you can feed Hall to both: inverter transistor and third trigger input. So you will be able to check Hall position by changing rising/falling in third trigger.
