idle scalars

im starting to work on my maf transfer and tb airflow & isc in EA but want to make sure im starting out with the right settings. my desired idle is 850. if i have idle in drive and idle in neutral set to 850 what would i put in for the isc max rpm in drive and isc rpm at CT? are those the only initial changes or does anything else need to be changed as far as idle? also when i try to datalog for the tb airflow & isc the car will die when i unplug the iac. i have the set screw one turn past closed and the iac two turns out. should i not touch those at all or will i have to mess with them to get the base idle?

i wanted to add ive read the tweecer tuning manual sticky and noticed it said to set the isc at CT 100 rpm higher than the idle in drive but i have also seen someone post on eectuning to increase all the stock values by the same amount. i want sure which one to use. adding the same number to each stock value would make more sence to me but i wanted to see what others use. also say i use the 100 rpms higher for CT what about isc max rpm in drive. would that be set to 850 also or would i add the 100 rpm to that also?
