IAC TF Decay filter and IAC Steps decay filterQ?

I see it is set high 9.75 and low 12.5 in stock LO3.bin. for TF. and 12.48 normal and 18.72 for St/SV(stall saver?) IAC steps.

Which way to move it to slow down its speed of movement over msec's?

Right now in log with slight AE event onset I move from 4 steps to 13 steps over 1.0 sec time. I would like to slow down IAC by about 25%.

I already moved TF min steps from 4 to 1. And moved TF TPS% Req 2 to 1.

this Q came from my thread "Bucking"

The TF IAC steps open as quickly as the throttle is moved, up to 160 steps per second.

The decay of the TF steps, a lower filter value is a slower decay.

My thought was the IAC steps were contributing to my bucking described in another thread. To reduce the IAC activity or frequency of change of IAC position I reduced the filter value by 50%. Did I go in correct direction on that? I have not yet loaded .bin to test.
