    That waveform above is correct for a tooth. However the area that you are getting confused with on the crank waveform is actually a "missing tooth". Missing tooth wheels are a little more difficult to see or visualise the correct polarity, you need to look at the gap area and you want the falling edge to be the most vertical zero crossing. Hopefully my picture below will help explain it, this picture shows the correct polarity.

    G4 Plug in permanently holding inj 3

    I think on the nissan the injectors are hot fed. So will have a permanent fed to them direct from the battery. Generally when a drive is damaged it will short to ground but I would not then expect a back feed. But I do think there is drive damage that will need to be repaired.

    I'm going to ask @Simon to comment on this one since he knows the internals better than me. It sounds like you possibly have a damaged injector drive but that doesnt explain the "back feed". Your inectors should not have power on the other side when you turn the key off so it sounds like there might still be a problem with the wiring too? Anyhow, hold off until Simon gives his advice.

    Hi Cozcorners There is many options, it depends on your requirement. Yes setting Log Trigger to rpm > 50 would work fine. You there using 800 rpm ???? My option is for my race car. So if speed > 25kph start logging until ignition is turn off. Allows the race engine to warmup and NOT record data during warmup, therefore saving memory to allow fast & many data points recording during the race. Possible explanation for your NOT logging, there MAY be a limit in the firmware on the number of recording starts. So once you start recording keep it active until the end. Only one start.
