I didn't want to use Generic VAG settings for the fear of processed data
Eh ? It's all processed data via a scan tool is it not ?
On the O2's, do you want voltages?
If your scan tool is not up to the job & I don't see why TPS wouldn't be available use the scope (same WOT-redline), TPS is purely to see & make sure your foot is nailed to the floor & RPM for obvious reasons. Throw another channel on for fuel pump current.
Manipulate the O2's KOER (idle(scope)) as well.
