Question about wiring 2 knock sensor on vems 3.6 .......
« on: January 07, 2011, 11:59:22 pm »
Hi,
I need some help about the knocks sensor connection.
My Vems 3.6 was ordered with 2 knocks sensor input signal.
I just need to know where do I connect the knock signal 1 and the knock signal 2,the sensor are already grounded.
In fact in the web/manual the Ec18 pin3 is used for knock signal,and Ec18pin2 for ground(for only 1 sensor).
But in the 3 page user guide ,found in the box when I received my Vems ecu, the signal 1 and 2 are put on the Ec18 pin1 and 2.
Can anybody can confirm this last Pin position??
Did some pin position different between the 3.3 and 3.6 version ???
Waiting your help :-\
Michele.

Hi,
I have wired it like you said, but look on the pin out table received with my Vems ecu:

The sheet you get with the ECU always overrides online documentation which is common setups. Your setup might not fit the common mold, which is why the specific documentation is sent to you with the ECU.

So just follow the sheet you got with the ECU and you'll be fine.
