Yes this does have a DPF & I was measuring at the tailpipe. I like the idea of connecting at the DPF Pressure sensor - can be a lot easier and less messy
Adding CKP & Injector Current is something that I will do when I get some time and then post the file. I will take some before & after captures when I fit the new injector.
However, in this case, my intention was to establish if I could stand behind a running vehicle and confirm if it did or did not have a misfire / running smoothly or not and then move forwards. All in 5 minutes without lifting the bonnet.
If that worked well my next step would have been to attach the First Look to a Handheld Scope (Snap on MT or Fluke 123) and look to achieve the same diagnostic information in 2 minutes without having to switch the Laptop on.
If a misfire / bad idling is suspected then additional channels can be deployed for Cylinder Identification.
I couldn't make any sense of the capture I posted
Other than to think that Cylinder 1 is also bad ?? It drives and feels as though it is running on three and not two cylinders.
Here I have used a Math Channel to Invert the capture and find that it is now closer to what I was expecting
I will have to check which way my First look reacts to Positive Pressure Pulses.
