Well, first off looking at your log. You're O2 is ok at .93, somewhere around there, maybe a little lower, is where you want to be but you really don't want to look at that too much for tuning anyways. Pay attention to you timing curve. You want it to start out like it does around 10 then rise nice and smooth to 18-22, somewhere around there, with no dips or flat spots on the "curve." Those flat spots or spots where the number drops are KNOCK! You probably know how bad that can be. Plus when your ECU pulls timing, your car feels like a dog.
You can't log IDC or IPW on 2Gs unless you've got DSMLink. And yes, you're most likely maxing out your injectors around 15psi.
If your injectors are maxed out, adding 18% isn't going to do shit. If they're stuck wide open flowing the most fuel they can, SAFC changes aren't going to magically make them flow more. So take that 18% back to 0, that's making you run pig rich where your O2v jumps a little, then your injectors are maxing out as you get up there in the rpms and you're knocking, hence the timing curve is all jacked up. "Compensation" is used to adjust for different sized injectors because your ECU thinks they are still 450s even though you'd have 550, 650, whatever.
Again take that "compensation" away. But yes, extra fuel (mainly used to absorb heat to eliminate knock) can "wash" the cylinder walls and prematurly wear your rings. It also contributes to massive carbon build up everywhere.
As for logging, only log rpm, o2, and timing. Adding mph or anything else can effect your bitrate. Rather than having a log reading every 200rpm like you do now, you can manage 100rpm by only logging the three basics.
