  3. BMW Dual vanos s54 VVT Setup

    in Link G4

    Hi!

    I cant get the vanos adjustment to work properly.

    Back to basic:

    I did the cam angle test
    Inlet/lh I got 114.7 
    exaust/lh I got  13.2
    I have been running 114 and 10

    both cam sensors are hall sensors, and I have pull up  ON 

    One thing I wonder about Is the vvt status, inlet/rh signal and exaust/rh signal are always highlighted in green and marked ok. The same with exhaust/rh and inlet/rh sys status  always marked  OFF or RPM zero.

    Is that normal?

    It sometime seems like it advances the  cam (retard for ex) and is unable to retard it

    Okay, now I am running the engine without error count.

    trigger mode set to  s54 v2/v3

    trigger 1 offset 272

    cam control mode s54 v3

    I am still having this issue with this

    in/lhcam target 0
    in/lhcam posn 59   

    in/lhcam target 0
    in/lhcam posn 0

    ex/lhcam target 0
    ex/lhcam posn -2,5 

    ex/lhcam target 0
    ex/lhcam posn 0

    I will email you  logg and my pcl file  to [email protected]

    Now I am running this configuration and no differens

    pin 1 green in-aux1
    pin 3 black in-aux2
    pin 4 green ex-aux3
    pin 6 black ex-aux4

    in/lhcam target 0
    in/lhcam posn 59 

    in/lhcam target 0
    in/lhcam posn 0

    ex/lhcam target 0
    ex/lhcam posn -2,5 

    ex/lhcam target 0
    ex/lhcam posn 0


    I wonder if it is an issue that I had to change crank angle offset from deafault s54  276 to (-360dgr) -85

    I found this numbers for the vanos connector

    VANOS connector pin 3: Intake cam advance.
    VANOS connector pin 1: Intake cam retard.
    VANOS connector pin 6: Exhaust cam advance.
    VANOS connector pin 4: Exhaust cam retard.


    Can anywone se right away that connecting (digital input 1 inlet lh) Aux 1 inlet LH to connector pin 1 intake retard instead of   pin 3 advance that it is connected now is the right way to go.

    Yes I have removed the diodes as in the help file, and ign +12 volts to pin 2 and 5 brown wires.

    pin 1 green in-aux2
    pin 3 black in-aux1
    pin 4 green ex-aux4
    pin 6 black ex-aux3

    I will try reverse aux 1 and 2 for in and the same with 3 and 4

    Okay, now I´ve tryed the V2 setting and it dident help me at all. Then I tryed to a cam angle test on Inlet/LH, I got stable numbers with pulse count on 6, but everytime I reved the engine above the rpm limit for activation 1200rpm I got different numbers, lowest nr was 89 (and later on 54) so I tryed to apply that nr to digital 1 input offset. It got a little bit better (even better with 54), but the idle got very rough. 

    So I tryed changing it back to default 114, then it work with 114, Only a few errors on startup and a total of 5-6 by reving for a few minutes. The idel are still rough noting like before.

    A clue might be found at runtime values, the Inlet / LH target value reads 0 (whitch I think is ok) but the Inlet / LH posn reads values like 45-55 on low rews just above idle. I wonder if I have wired the advance and retard solenoids the wrong way around. Dont remember the values for the exhaus / LH but I think it was about -2 on low rews.

    Could you please help me witht this

    Hi 

    On startup I was running dual vanos s54, and was geting error counts on EX/LH in vvt error counter / runtime values. I tryed changing it to dual vanos s54 v3 and I noted an improvement at low rpm changes but are still getting some error counts. I´ll try the  v2 setting later this evening. If it dont help do you think the right way for me is to determine the correct cam offset by trying to do a cam angle test on  Inlet / LH  that is connected to Digital 1, or must I do it on all four. And at what pulse count should I do the test.
