Updating to version 0.10 solved the issue.
I'll pick and try your changes.

Re: Subaru GC8 EJ20G five years later
Trying to setup ilde and coasting.
1. Looking at vertical scale... "Multiplier" should be "Position" or "Percent" in Coasting IAC for auto-idle?
2. RPM on current screenshoot is 2000. Coasting is green. But IDLE position oscillating between 90 and 70.
I tried to set really low values in this table in case it is Multiplier...
IDLE position is still high. What is used as a base for this Multiplier?
@mck1117 this is your open-in-closed branch...

Re: Subaru GC8 EJ20G five years later
it looks like its chasing its tail because of the deadzone - it's oscillating maybe 75-100 rpm, because the middle 50 rpm aren't doing anything because of the 25 deadzone. Try setting deadzone to 0, P/D gain to 0, and slowly add I gain and see what happens. Your min/max also need help - those are the min/max amount of CL adjustment, so they should be like +-20 or something, probably less than that once you get it dialed in.
It may also help to enable "use idle ign table" and "use idle VE table", as those will help smooth out any impact of timing and fuel changes. You have some in-phase oscillation in lambda, which will vary the engine torque (richer, down to about 0.85, will generate more torque than at stoichiometric 1.0 lambda).
