So I've been trying to tune my idle so that I can basically turn on the headlights, heater fan, and radiator-a/c fans all at once just to put as much load on the system as possible to see how much it dips/jumps.
I can't seem to make it a smooth transition that's as perfect as I want.

Do I have to settle for a mediocre control that jumps with such a large increase in load?

Here is a log showing the dips and the map I'm currently running.
