Getting a handle on the IAC
I've not found anything yet that obviously and clearly would allow me to control the gain of the IAC motor. This is an issue because... well feedback controlled systems have a nasty tendency to go into uncontrolled oscillation if the gain gets too high and it turns out (unsurprisingly) that this system is no different.
Now a lot of different factors affect the end result of the signal going to the IAC motor in a lot of different ways but in the end, it has gain controls somewhere. I need to know what they are. I have an idle oscillation and the IAC is leading the parade.
Any suggestions?
