Once you get to this stage you can keep being more and more meticulous on the "peaky" areas. Couple suggestions to make life easier. Make sure when you pull the data the car is COMPLETELY WARM. Heat soak affects everything too. Outside temps near 75 are ideal. Major temp ambient temp swings definitely will affect results too.
Flash it. Let it learn in. few drive cycles. long data logs which you are already doing. Adjust a range. Rinse. Repeat.
Keep doing what your doing...
-Do you think my 1 hour long commute on the highway is causing a bunch of heatsoak that are skewing numbers?
-And should I be driving it with the new adjustments a few times before datalogging again? I have been adjusting at work, uploading it to the ECU, and datalogging on my commute home, looking at the graphs, adjusting at home, uploading to ECU at home, then driving to work in the morning and datalogging. Too frequent?
I really appreciate the advice! it's actually pretty fun trying to figure all of this out, and all the help I can get is only making this much easier.
Another quick question: If i'm running a little lean or rich while I am trying to datalog and fine tune and adjust, I'm not going to add any risk of damaging my engine, correct? From what I understand, fuel trims are the ECU correcting the amount of fuel to match the target AFRs. So the cars are technically not running lean or rich, they just need adjusting so the fuel trim process isn't always working non-stop. Is that correct or am I misunderstanding that?
