My friend asked this question a couple of days ago on here and his answer was that you need to wire it up to both as each wire on the ECU runs 3 cylinders. So you need to wire the SAFC wire up to both.

ya you only hook it upto 1 sensor.. as per the instruction manual

if the 1 sensor doesnt work, jus try the other one

Mate just been informed that you hook it up to the sensor with the strongest single according to the safc2 book. Might be an idea to PM predator on this one.

I reckon if you wire it up to both then you will effectively be shorting the connection between the two unless you put diods in line so the signal can't go from one line to the other.

I don't know that this will actually matter though since a knock is a knock no matter which sensor heard it first.

very true, i left it alone on knock 1 after the seting it set on 0 but during the setting its arounf 35-40 is that normal?
