Supercharging BMW E90 N46B20 320i 4cyl

[SlavPala4a]

There is a TB which in my case is called Valvetronic. Valvetronic is controlled generally by the DME(ECU) via several sensors. I will post later the technical information about the DISA and Valvetronic systems in my engine.
I was telling that the usual TB which is fastened to the Intake Manifold inlet works as a normal TB only when there is an error in the valvetronic control.
I am also selecting some of the most important information about the Mercedes's system which I am going to post later today.
See you
