Still trying to figure out my BDX programmer

I would call SCT help line I am pretty sure you can add the pids thru their software and upload to the bdx tuner

It should and you should see it listed as Knock Sensor 1. But as @MY27FUSION said above you may need to add the PIDs you want into LiveLink and then create a config file to load into the device. Not all pids may be available to select from without doing that.
