data Logging questions

[Jlamb4444]

I am trying to clean up the fueling and spark on my F150. What is the best method to collect a log file? Long WOT from idle/stop? How long should the log file be - just until I run out of road?
Record ST and LT trim? Then what is the goal for the fuel trims? What about timing advance? Any and all help is appreciated...

2006 F150, Diablo Sport Predator legacy tuner, 5.4L, Corsa cat-back exhaust, S&B CAI. Nothing else...
