Poor Cold Idle (Yes I searched)

Disabling bit 11 causes the condition (I'm sure you already know this). I don't think anyone has found a table that will fix it though, with the bit disabled. I know I went through every table in ecuflash trying to fix it to no avail, until I reenabled the bit and it worked.

What coolant temp are you logging? I logged coolant temp scaled (evoscan) and it was always at 154.4*. The second it hit that my rpm jumped up for a second, settled out, and then the car idled perfectly from then on. Even if I did a warm start and coolant temp was less than that it idled crappy until it heated back up past it. Although it did seem to get progressively better as it warmed up.

The other thing to check is if you have scaled your MAF down at all. I think this plays a part in the warm-up fueling also even if it is perfect once warm.
The interesting thing was that when i did this my scaling went to an almost-perfect expected value (~1150*.7(ecuflash scaling)*.7(e85)). I lowered the latencies quite a bit, but you may not need as drastic of a change.

I also noticed in my case that it was right around a certain coolant temp that it would go from bad to good. Can't remember where off the top of my head though.
