Message Cjw3,
Thank you. I will do that with the software the next time I have it hooked up and warmed up: Cylinder Idle RPM Drop Test. = Drop each cyclObserve amount of change or no change in idle speed to determine “weak” or “dead” cylinder(s). Allows shutting down individual cylinders. If all of the cylinders are producing the same amount of power the engine RPMs will drop exactly the same amount on each cylinder that is cancelled.

For now, though:
Here's how it looks with the software:
