Depends on what it is you want to monitor. If you're testing out a new tune I usually like to see my octane adjustment ratio along with the cylinder corrections for all 4 cylinders.
For DD and pretty much any other time it's dependent on what you line to monitor, I have mine set to Boost pressure, oil and coolant temperature, charge temperature, AFR and last one cycles between octane adjustment ratio or Cylinder 1 corrections(that's my problem cylinder)
Other commonly monitored ones are intake air temps(temperature of the air coming into the car), ambient temperature, estimated torque and HP as well. You can swap out any of the ones you feel you don't need and mix and match until you find a combo you enjoy.
