Wheel Oscillation IR-18 in iRacing
-
Hello folks,
I’m using the latest software which happens to have the default sim settings that I like.
My first question is what does the Hz slider do (be gentle I’m no technician). I read that iRacings FFB works at 60hz so I changed from 50 to 60.Anyway, onto my main issue…my main drive is the L49 in iRacing. I drive other cars and have no issues. However, I tried the IR-18 fixed at Road America and on the straights my wheel was rocking back and forth to a point where I couldn’t focus
.
What is the cause of that. I will probably avoid the car. I used to have wheel centre weight turned on but found it just gave me a pendulum effect in the MX4 advanced if the rear stepped out. -
Can you post a screenshot of your Settings & Advanced tabs in your desktop app as well as your iRacing FFB settings?
We'll configure accordingly at this end to see if we can replicate the behaviour and work out why IR-18 behaviour differs from other cars within the sim. -
There you go guys, thanks.
For iRacing I set the wheel value at 20Nm and the Force/Scale doodad I usually auto but most cars are usually within 10Nm. I added the 2% weight recently (prior to this request). I usually drive the L49 and that can take 20-22Nm of Force with my 7 caster setting and 10:1 steering ratio.
I’d be interested to know what the Hz setting does (I read iRating use 60Hz) and someone on the forum said reduce the speed and have a narrow range of weighted centre. I’ll wait to see what you think. It’s the only car I’ve experienced this in and I’ve driven lots! -

Ollie, I read and replied to your post on the iRacing forum. Thanks.
What effect does Bandwidth have on the whole?
Also, the speed of the wheel, is it better to have it faster or slower? Default is at 200. -
Bandwidth dictates how "tightly" the motor is driven. An analogy would be a car's suspension. More comfortable the softer it is set but with the likelihood of overshoot, more precise the harder it's set but less comfortable overall.
The default Bandwidth setting of 0.5 is chosen as a compromise between accuracy and comfort but with the IR-18, the theoretical added discomfort of running at 2.0 is offset by the reduced effect of the oscillatory behaviour inherent in the input signal.
For cars without as extreme a FFB response as the IR-18, you want the Max Speed value as high as your preference dictates. It is a secondary tuneable i.e. it modifies the behaviour of Weight by altering the threshold at which it starts to be applied.
If the car is sufficiently well-behaved (e.g. the Formula Vee), Max Speed @250 & Weight @0.25 is possible

Thanks Ollie,
those settings were great. I've responded further on the iRacing forum.
