You can try it and see if it works better for you. My base bin was BJYM. You can dowload that from here http://www.gearhead-efi.com/Fuel-Inj...2&d=1321320663
The only problem is if the idle is higher than commanded , you may set an IAC trouble code because the pcm cannot lower the idle any lower after the IAC goes to 0 counts. Usually you have the least IAC counts when engine is hot and the air entering the intake is warmer. To help cold driveability, it helps to have a thermac type air cleaner housing and it pulling warm air off the exhaust manifolds into the throttle body. You could fab a hot air tube off one of your headers.
I leave PE and AE enabled while tuning. I filter out both when doing normal VE tuning. For PE mode, I adjust the VE so it matches as close as I can to what I have set in the PE AFR vs RPM table. You can watch the INT during AE events and see whether you are lean or rich during AE. That is what is usually takes me the longest to get close. As for full time open loop, I have never tried it. I ran open loop idle for a while but now run closed loop. You could try to set the minimum temp for closed loop up to the max under closed loop qualifiers and that should make the PCM stay in open loop.
