  1. Just trying this now,

    I've just done a timing calibration again and the difference when swapping from rising to falling is very small 2-5 degrees ( -120   -125 ) , Also hard to tell on the starter motor.
    Fixed at 10.

    Still just fires once then stalls when on falling.

    What am I missing ?

    ** UPDATE **

    Just got this working, I needed to set the dwell to 2.5ms for the MSD DIS-4 unit..
    Tested by swapping to 1ms when running , and the engine stalls


  2. Hi All, hope someone is able to help me out.

    The project is a Nissan GTiR, Link LEM 3G.  I wanted to switch to direct spark so got the following

    cbr 600 coil-on plugs
    Plug that fit into the above
    MSD DIS 4 

    The car runs find under light load.
    The problem I am having is a misfire under load. What I have found is that the larger the dwell number the worse the misfire.

    I read that dwell had no effect when running CDI ?

    When running 0.5ms I get a small missfire over 5000RPM over 14PSI
    The more I turn up the dwell upto 4ms the sooner ( Less load ) the misfire happens

    The Spark time is 1ms
    Anyone any any advise ?



  3. Hi Da'ninja,

    the G3 to G4 upgrade is just a paid for upgrade, it is very easily done.

    You need to contact your nearest dealer and purchase the upgrade code etc.



    I contacted my local Link dealer asking for an upgrade price , and they told me that they had contacted Link and "you" advised the following : :

    "Connect the ECU to  the lap top and save the map, update is free of charge through the Link website, the map will need re-installing following the firmware update."

    Is this true ? or what other link dealer can I use i? ( UK )
