wheel oscillates violently at bump stop

[roylan101]

I use a simucube sc1 and when approaching and hitting the bump stop for the car in iracing, the wheel starts to vibrate/oscillate very quickly and makes it dangerous to grab the wheel.

When not using irffb, and increasing this setting in iracing's app.ini:

steeringBumpStop_Deg = 180

I do not get the oscillations at the bump stop. This setting does not work in irffb.

It seems that irffb is bypassing this setting. Is there a way to stop irffb from bypassing app.ini, or perhaps add this setting to irffb? I am using the latest version, 1.4.2, which claims to stop over dampening of bump stops.This happens whether or not I use vjoy, and with any of the FFB settings (360 hz, 60 hz filtered). I have also tried with the 6.6.2 version that allows use of 2.1.9 vjoy, and still nothing.
