    BMW Dual vanos s54 VVT Setup

    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 itÂ

    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 tech@linkecu.com

    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 59Â in/lhcam target 0 in/lhcam posn 0 ex/lhcam target 0 ex/lhcam posn -2,5Â 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 Â 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

    I forgot to inform you that  I´m running V3 mode now, it seems to work best for me.

    BMW Dual vanos s54 VVT Setup

    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 Bjorn

    BMW Dual vanos s54 VVT Setup

    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. Bjorn
