I bought the car with it retarded 6 degrees (timing was retarded to pass smog I think, oxygen sensor was slow before I replaced it so it would flip flop between high NOx and high HC on the smog test,) when I got my hands on an inductive timing gun I advanced it by 9 degrees for a 3 degree advance.

72 MPH is to simulate heavy loads like seen in P&G. I'm not going to watch my multimeter while accelerating, doing it like this gives me more time to determine where the engine switches over to a burnt in A:F map so that I can keep the car at the very limit of running closed loop.

No. 72MPH is 3600 RPM or so, it stays closed loop until at least 4000 RPM in other gears when under lighter load.
I need my data cable, but I lost my high wattage soldering iron.
