Hi all, I am about to install a Nanoplex system to my 650 engine and i am trying to understand how the vacuum switch that is connected to the intake manifold operate. I was expecting that this switch was closing after some engine revs but i noticed that it is switching all the time, it is like measuring engine revs. anyone knows if this is normal? I have a copy of the manual but unfortunately it is written in Polish.

in those drawings there is a damper (called 'dlawik') on a pipe from intake manifold to vacum sensor (engine load sensor)

Yes I now know that and I have installed it. Actually this extra system only operates when engine is under high load, for example in a hill with 3rd gear and throttle all the way open. It then changing the advance of the engine.
