Once it is in adaptive idle it can change the spark and iac by how far it is off of commanded idle. For the iac it uses PID settings. So how ever you have those set up is how fast and how much it moves the iac in or out. I don't find the derivative useful but the proportional and intergral definately do. It takes a little bit of studying up on those to figure out how they all interact to get the idle sorted. Fueling is also real important. You should do a log with the wideband reading and post it up on here.
