  1. Thanks

    There are any number of trigger wheels available in terms of size, diameter, tooth setup, it shouldnt be too difficult to fab something up for a solid reliable trigger.
     
    On my old RV8 and now LS, I just machined the rear side of the crank pulley a little then welded a 36-1 wheel onto them and added a VR sensor ( done before the LS 24x was accommodated on most systems, although the 24x wheel they use is shite and I wouldnt use it now anwyay )
     
    Trigger setups can be done very cheaply if you want. My wheel and sensor would easily be less than £100 total.

    Just wanted to clear the VAG coil wiring diagram. These coils have two ground connections when in the OEM installation . One is for the secondary coil - wired to the cyl head. The second is for the coil driver - wired to the chassis/ecu ground.

    There we go.
    Granted the RPM line itself is smoother than what i suspected. Could be because of slow logging rate. What gives it away to me though is looking at the RPM ROC parameter. Thats RPM Rate Of Change. How much the RPM changes over a second. Anything over 0 meens RPM is rising at a certain rate and below 0 means its falling. We bot KNOW you are accelerating so the CRANK is certainly not slowing down, right? However you can see i both my screenshots that the ECU is logging a very erratic RPM ROC. It should ALWAYS be on the positive side when the engine is accelerating. That IS the CAS flapping around. There is also some knock registered in one of the logs. I bet because of unstable timing.


     

     
     
    Never mind me saying it looked smoother than expected. I just wasnt looking close enough at it. Its actually one of the worst i have ever seen

     
    You sir, are going to install a cranktrigger before it breaks down completely

    I fabbed a simple bracket and bolted it to my ac pump bracket. Drilled and tapped. I have also seen it bolted to the other side of the oilpump on a simple bracket. See if you can find pictures by member lostsoul here or at the aus300zx forum.

    This is the type of thing that would normally be used:  https://www.ebay.com/itm/292427582383
    You definitely have trigger errors but it is hard to tell if it is due to interference or some other problem.  Im not sure how much we can rely on the built-in triggerscope to show good detail of the Nissan 360 slot trigger at high RPM - I think it is possibly a bit beyond its capabilities.
    I think the trigger voltage dropping away at higher RPM is due to the filter.   Trigger 1 filter should be set to 1 for high tooth count wheels - can you confirm you have it set to 1?  If not can you do another 5000RPM triggerscope but with trig 1 filter set at 1.
    Did you try switching on low resolution mode?

    Ecu is powering up from ignition switch input
    Change main relay to test on and see if the voltage increases

    I'll make a new wire and connect it to a new and good chassis ground and to "Plug C - PIN 8(Main Relay -)" and test it.
