rundown on EGO: ignpulse vs. msec - rate of change for ego compensation. milliseconds (fixed throughout RPM), or ignition pulses (RPM, basically). controller step size is how much it'll adjust injection pulse per change, authority is how much it will allow it to change TOTAL. Active above: pretty self-explanitory. around 140/160 degrees is fine, and RPM is when you want it to kick in. I have mine at 500, between crank RPM and idle, that way it'll control idle mixture as well. Sometimes this is a pain, and many people have it around 1000/1200.
