hi all
please help me understand how our waste gates and controllers work, on my bew the vnt vane also known as wastegate is operated thru a electric actuator and a vaccum source for probably sensing the boost, now as we move the pedal to demand more power the difference vaccum pressure on either side of the butterfly valve should send a signal to the fuel source and also controll the waste gate to keep a well balanced operation.
in my case my turbo wheel sheared off and was stopped by my 02 sensor. i replaced the turbo, set the vnt arm similar to the old turbo, cleaned my intake, replaced my 02 sensor, but now i cant rev more than 3400 rpm downhill, and going uphill as i depress pedal for more power it stutters and by lifting off the pedal it slowly creeps uphill, once on a staightaway it rams again all the way up to 3400 rpm .....
is there a way a detailed procedure to rig and adjust all the inputs and output signals to trim the engine for best power and fuel burn.
does any body have a vag cable that can be rented or borrowed.
best regards
Vahid
