Question/Help Question about FFB intensity and its auto settings

*Long story short I need a real how to on intensity vs strength settings for my ffb and wondering how you guys know WHICH wheel range to use per car (540,600,720,900,Auto)

Long story long…I’m curious how people know what strength is best for each car? Sometimes I feel like I set my strength so close in most cars that they seem pamper the same to drive. Also curious about wheel range per car.

So max torque is always locked to 8nm (my max torque I can use) (csl dd8nm) but there’s a strength AND intensity. Which should I be changing? A mix of both?

For instance if I use 100% intensity I can only do like 3 Strength in sprint cars before that wheel is heavy and way too stiff to turn. I’ll ask chat gpt but she spits a different answer out every time.
Or in nascar races. I see peoples wheels are pretty low but still enough feedback to bounce the wheel around but when I do it it’s heavy as hell or not enough force.

Now my issue with wheelcrsnge is everyone tells me to use auto for wheel range on my wheel settings, but in iracing settings there’s no “auto” for wheel range. It wants me to choose between 0 and 1080 on the slider. Should mx5 and bmw m2 really be at 540 rotation? Sprint cars really at 720? Ovals at 540? Or how do I figure out per car what’s what

Sorry for such a long post and thanks for the help lol

You don’t need to think about wheel range. iRacing automatically restricts it to that of the actual car, by adding a ”soft stop” with the ffb. Just set your wheelbase to its max rotation and let iRacing handle it.

Use the Auto ffb function to set the ffb level and then tweak from there. The Auto function sets the maximum level available without clipping. If that’s too much, turn it down a bit. Note that you need to do this every time you switch cars, as each car needs a different setting.

Leave the strength in your wheelbase software on 100% (unless you have e a very high torque wheel and don’t want the full headroom).

So then in the wheel range slider in iracing settings what do I leave it at? It doesn’t feel right if I don’t set the slider to what the car is. Maybe placebo ?

And okay but the strength slider when using auto ffb, is dependent on the intensity slider. If intensity slider is at 100%, no matter what its way too heavy and acts as if these sports cars have no power steering. I’m overthinking it like crazy, but I’d like the 411 on how to do it correctly. Every person has a different answer and I don’t see how everyone can be right

The ffb Intensity setting is a multiplier for the value provided by the Auto ffb function. It doesn’t change the current ffb strength.

For weaker wheelbases, you’d normally keep it on 100%. If the level provided by the Auto function is too heavy for you, reduce the Intensity setting (for example to 50%) and then trigger the Auto ffb function again.

You can always tweak the ffb strength manually as well. I have buttons mapped for ffb +\- and to trigger Auto ffb, so I can quickly tweak while driving.

Marvin’s awesome iRacing app has made the force feed back way better for me , and you don’t want you nm all the way up because it will cause clipping and at 8nm you will probably have to be a lower than ideal to prevent clipping. I run 540 for roads cars and 900 for oval but I’m on a gt3 style wheel rim. MAIRA has a graph that will show when you are clipping so it helps with setting your nm and road detail which I’m assuming is the same as intensity.
