    is your new trigger setup common to modern ignition timing systems? is that what they call a crank angle sensor?

    It would be called a crank angle sensor, and it is common to one or two modern Engine management systems.


    Everything is model and system dependent, but some random samples;
    BA falcon uses a 36-1 tooth Inductive CAS
    BMW often has a 58-1 tooth Inductive CAS
    Nissans often use a 360 slot optical CAS
    Mitsubishis often have 6 slot Hall Effect CAS

    Also a lot of systems use a Cam position sensor as well.

    Thread revival time!
    Pumbas old engine that is still in running condition has now come in handy:



    Into the spare frame.



    Manifolds on.



    Throttle bodies on.



    Crank trigger on.



    #2&3 coils on.



    Because the rocker cover bolts are designed to tighen fully at a set tension on the rubbers, some care was needed to find a solution. Proper spacers are for later, as is rounded egdes for the brackets.



    #1 coil bracket



    #1 coil in place.

    Next is to finish off the cut and shut fuel rail and find someone who has both a gas axe and can braize.

    The sensor(s) are factory XJ750, the cutter wheel was custom made by a forum member to my measurements.

    Others that have tried it have had to remove the second sensor because of interference. I would like to keep the second sensor as a spare.

    Technically if one sensor failed, you could use the other and just swap coil leads to make it work for a backup.

    Can you adjust both crankshaft sensors individually angle wise? You mentioned even if the sensor wheel wasnīt in the perfect position you could allow for that on the software side later on. What about the second sensor? Had one hell of a time when I changed from crankshaft to camshaft with the pickup as I couldnīt make the sensor wheel accurate enough. The second mark was 2 degree off and so was the ignition timing and I couldnīt decide on which I wanted to set it while cranking it with an electric drill and timing light and it jumped only that increment. Second attempt was then to have the second mark somewhere else way off to be able to set the timing correct while cranking her over. Needed to have two marks to simulate higher RPM to the CDI in order to have the spark advanced properly. Was just wondering if it was easier to be achieved with your modern techniques. Looks really good

    I will only ever have one crank sensor connected to the ECU at a time, so it wont need individual adjustment. Because I will not be running a cam sensor, I have to run a waste spark spark system - even with the individual coils.

    hey darkfibre, how is the EFI on Pumba going? It looked you got it ready for test run! Did it work out OK?

    Great rebuild on Pumba & now this! please update =o)

    Nice build.

    I'm guessing the old ignition would not have had any ignition advance where as, clearly now you will.

    Quick update.

    As part of moving out of Perth, the project got put on ice.

    Pumba (XJ750) was sold as a carby bike, as the injection added zero resale value.

    On the positive side I have stored in Perth all the parts required to finish the project (on a different XJ750 at a later date)

    Should be back in Perth end of 2018 (small chance of end of this year)

    Cheers.

    Dear DF, I am the proud and yet frustrated owner of a 1975 Norton Commando Mk III. I have taken the decision to modernise the bike, one aspect which has intriqued me for a long time is after market EFI conversion. Do you run a shop or can you advise of someone in Perth who I may speak with regarding investigating the possibility of EFI on my scooter?
    Thanks
    Michael.
