    rzempel, I shared your confusion. After doing some research, I finally found this photo of the setup. Rather than use the flywheel teeth with a reference peg like some cars, there is a large 36-1 wheel that bolts to the face of the flywheel.

    Yes John that is exactly what I THINK I have.
    I am going to get my wife to slowly spin the engine while I shoot a video through the CPS housing to verify missing tooth...but I think that will be OK.. I can see that their ARE teeth similar to your photo so that’s probably OK.

    The fact you can see the teeth is good. The part that still confuses me though is the fact the ECU is reading an engine speed, but it's wildly off and seems to vary. Does the Omex have a setting for different sensor types (e.g. Inductive, Hall effect)? Perhaps that is set incorrectly?

    Have you adjusted the gap yet? If not, that may be the answer. As per this post on WSCC, the person had the same issue with an Omex. Reducing the gap from 0.9mm to the recommended 0.3-0.5mm resulted in Stat Sync'd changing to on: https://forum.wscc.co.uk/forum/topic...omment=1385171

    Chrysler used a neat trick to set sensor gap, they applied a piece of paper to the end of the sensor and you installed it with the paper hitting one of the teeth and tightened the mounting hardware. This set the gap. Once the engine turned the paper was knocked off and you were good to go. Simple and accurate. Maybe this would help to set the spacing for your car????

    Back to the old ages. Supposedly one could set the gap on Triumphs with cigarette paper. Motor bike and breaker points though.

    Hi Andy and John,
    Thankyou.
    I am currently working on the gap right now.
    I screwed it up yesterday and took a chunk out of the end of one of my sensors
    currently working on my spare sensor ;-)
    I like the idea of the piece of paper or in my case tape on the end of the sensor I’ll let you know how I get on

    Also glad to say that I have verified Through the CPS hole that there is a tooth missing at 90 degrees below top dead center....
    now back to the gaps.
