Default Can somebody check my cold start and idle settings?

Can somebody who knows what they're looking at take a quick look at my msq?

I am having two issues.
1. Cold start has never been very good. It starts eventually every time, but it will crank a few times, catch, crank some more, catch a couple times, crank a little more, then finally go. I decreased the ASE a bunch this weekend and increased the WUE a little, along with the cranking pulsewidth, and it helped, but it still does pretty much the same thing. I'll keep fiddling, but I'd like some confirmation that my numbers are at least in the right ballpark.

2. Idle. I actually don't think this is a tune issue, but maybe you guys can help me figure out where to start. It idled fine for a couple years, and I was happy. This spring (I had not touched the tune at all in 2 years), it started struggling, and then stalling, when I would put the clutch in around corners and while approaching stoplights. It has slowly gotten worse over the summer, even though I have not touched the tune or idle screw, or anything.

I would be very grateful for any thoughts on either issue.

The three files are a datalog of a typical cold start, the associated msq, and an msq after a couple more tweaks, which is what I currently have in the car.
