How do you tune open loop values ?

Hey all. I'm trying to get my car to idle right when I first start it in the morning or after it's been sitting for a while. Plus make the coughing and backfiring go away while I'm in open loop and like 5% throtle. I'm at my wits end... can someone take a look at my bin and tell me if the open loop values are at least in the ballpark ? Part throtle is great and WOT performance is awesome, but when the car is cold it runs like crap. I have it posted it here if anyone wants to help. It's a speed density 8D bin. http://www.truspeed.org/current.bin

Thanx in advance.

Cold open loop stuff is frustrating, even after a thousand chips. Take notes and go gradually.
There really aren't any universal answers for what will work with your combo. Might look at a few other 8D cals ans see what ya see.
