HOw to tell which paramater to select

Ok so you picked all your pids you want logged now your trying to set up say a table for spark retard. It's logged RPM vs spark (cylinder airmass). Now when picking the proper columns and rows in the table setup how do you tell your picking the same one you have chosen as your pid? Like cylinder airmass there are a bunch of them.

I don't know, I just load them until I find the right one.

its trial and error with the channels

once you find the correct channel to log, you can use the gear icon to only see the logged channels (when creating a layout) but that option is not avail for determining which channel to add to the channel list
