It would be handy to see RPM on the oscilloscope to see what the EGR is doing at certain revs. Also good to see the other EGR options on there as well.
I tried EGR TP, not sure what this shows as mine stayed at 2%.
I'm tempted to have my car Terraclean'd to see how good it is, and how much difference it makes, but I want to change the car.
I'll see what I can do, will have to have a play with the software on Sunday
