    Hi Guys.
    So tell me about cranks trigger set ups.
    So I understand that the crank trigger works in conjunction with a cam sensor so it knows a home position?
    Can you use the factory CAS?

    It depends on the patterns available in your ECU. In some cases the cas signal is only referenced for starting, in others it is referenced every revolution:

    Yes but it will need to be modified to provide a home signal once per revolution rather than factory home and positioning signals.

    To run sequential, you need the cam reference.

    For information sake. I used a modified cam sensor briefly during the process. I pulled apart a sensor, and put tape over the disk leaving only one trigger slot. It worked well, but I wouldn't advise as a long term solution. A better one is the AEM 24 and 1 disk replacement (Using the and 1 ring). This was my first choice, but I was having trouble getting one at a reasonable price in the timeframe I wanted).

    An even better cam solution, is the NZ Wiring and Performance trigger disk, assuming you can come up with a simple bracket to hold a Cherry or GT101 sensor. This is what I use currently.

    For me, going this far and still using the CAS is not ideal. There are enough cases of CAS pin slop and bearing noise to spend the extra few bux on something hard mounted to the cam gear. The NZ Wiring disk was ~$70 NZ from memory.

    Thanks guys.
    What do you mean by hard mounted to the cam gear?

    I’ll be using a Fueltech 550

    The trigger disk bolts under the 4 bolts that attach the cam gear to the cam

    Ok I think I have it.
    So rather than replacing the disk within the standard CAS, a more accurate reading solution is to directly fit a disk to the cam wheel and mount a sensor to read that?

    Is that what the Ross cam sync does?

    Yep exactly. There's a few pics in my build thread
