After everything else was set properly I noticed that my idle was up around 1100 rpm. Also noticed that I was at 31* btdc at idle. Corrected the timing down to 12* btdc at idle and it brought me down to ~860 which is where I wanted to be for right now.
I used the functions Idle-Spark vs ECT and Idle-Spark vs RPM to get it down where I wanted it at idle and reset to all in by about 1800 rpm.
For starters I reset the "base idle" buy unplugging the SPOUT connector and the IAC (also called ISC for Idle Speed Controller) and mechanically set the idle to the point where the engine would just barely run without and input by me via the idle stop screw. Ended up around 650 rpm. Plugged everything back in and started making adjustments in the system to get the idle where I wanted it. By setting this base idle it insures that the system is controlling the idle
