MY17 AT K00D E85 tune here. I've noticed that my rpms spike for a sec on a cold start when putting the car in gear. This causes an ever so slight jerk despite my foot on the brake. I suspect it's the multitude of "idle speed target" maps not matching and picking a different rpm once in gear.

Which of the 9 "idle speed target" maps are for what conditions and are they safe to modify? With cold start removed do they even need to be anything other than 700 across the board or is the higher rpms just for getting the engine up to temp? My intent is to make the maps for base start and in gear match so that there isn't a spike at cold start.
