Guest |346| Posted September 24, 2009 Report Share Posted September 24, 2009 Which polarity is correct for the 60-2 trigger, I am having trigger problems above 5500rpm. The green is the crank and the yellow is the cam traces. I have been using this: Should I be using this? Quote Link to comment Share on other sites More sharing options...
Guest |346| Posted September 24, 2009 Report Share Posted September 24, 2009 Well I'm running the second way and it has cleared my trigger and power loss issues. This wiring is OPPOSITE of the factory bosch control which requires switching wires 1 and 2, and has what appears to me to be a negative spike followed by a positive, as opposed to the other way around as required in the manual.

rayhall Posted September 24, 2009 Report Share Posted September 24, 2009 Jason, Do not see why you had to ask about the signal on the forum, as in my reply to your email I told you the signal was upside down. Now that you have changed it, the signal now rises before falling, which is what the Vipec ECU and all other ECU require. Quote Link to comment Share on other sites More sharing options...
Guest |346| Posted September 24, 2009 Report Share Posted September 24, 2009 I was just trying to increase the usefulness of the search function on the forum, as it looks to me like the signal falls before rising in the second trace picture. This is in addition to having to reverse the polarity of what the factory motronic uses, which is also why I figured I would add this to the forum archives.

rayhall Posted September 25, 2009 Report Share Posted September 25, 2009 To add to the usefulness of the information, the signals at the start and end of the missing tooth area tells you which way around the signal is. When a missing tooth is occurs, the signal goes much lower then when it sees the other side of any other tooth. Then as the first tooth after the missing teeth the signal will go much higher then all the following teeth. Ray. Quote Link to comment Share on other sites More sharing options...
Guest |405| Posted September 28, 2009 Report Share Posted September 28, 2009 That in part was the reason for our troubles in the BMW S54b32 BMW trouble @ exactly 5500... Quote Link to comment Share on other sites More sharing options...
Guest |304| Posted September 29, 2009 Report Share Posted September 29, 2009 So how does this look for the Subaru 36-2-2 wheel? To me it looks like it triggers on the downward slope so I should be ok but my waveform doesn't have quite the shape of the Bosch 60-2.[attachment=0]Subaru 36-2-2-2 scope capture.jpg[/attachment] Quote Link to comment Share on other sites More sharing options...
