Closed-loop idle control

Do we have issues with the closed-loop idle control feature these days?

I've been trying it on some different setups during the last couple of months, but I could not get it to respond as intended.
Decided to give it another test on the testbench today.

Within the idle RPM upper limit, it seems to only be advancing, but never retarding ignition as RPM floats around the setpoint. It also jumps straight to the maximum adjustment setting regardless of proportional gain, which makes it completely non-linear.

Tune and log of the test:
