CA18det tuning - Knock sensor frequency + more questions

[Zenki]

I'm using the Phormula KS-4 on my CA, it works really fine. It hears knock before you can hear it with your ear, thats my experience. You can also import the signal @ nistune

If you have a small budget, I would go for an CA16 inlet cam

Are you actually logging the phormula knock sensor into Nistune and if so how and what type of signal type is it logging?
