well, this isn't quite true: it will still advance with it disconnected (13' 
+ base timing). maybe just not as much.

i'm losing faith...
one last question. what happens to the car at wot? pretty much my 
understanding is that vw gives up on fuel economy, and things get simpler: 
you're running open-loop with the o2 sensor, and if i understand correctly, 
the dpr gets a fixed current at wot (16ma), which would make the fi 
basically mechanical at that point (no dpr modulation, based strictly on air 
plate height?). how bout the ignition? does it do something similar? maybe 
say "screw the other inputs, i'm going to my preset ignition advance unless 
the knock sensor tells me not to"?
