OSR has an Indycar series running on Sundays if you are interested. Great group and an awesome car.i also use a TMX and agree that there is less drop in grip than i maybe expected.
i have settled on this config (albeit i am nearly always driving the 2018 Indy Car mod - which may have a different feel to the standard cars)
TMX control panel
Overall strength - 75%
Auto centre = By game
FF strength = 72%
FFB low boost = 40%
Guess its all personal preference but seems to work for me. If i ramp up the feedback more, my shoulders are buggered after 30 mins !!
OK so I gotta know something here, cause its driving me crazy.
On some cars like the Abarth mod, the effects are awesome, and I can feel the steering wheel pulsate when it understeers, exactly how I want all my understeer feedback to be.
But on other cars, like the GT4 add-on and to some extent the EEC GT3 cars, I cannot feel much understeer feedback.
I gotta know, is this because my FFB settings are wrong for the GT4 and EEC GT3 mods, or is this something that is more about the way the cars are modded?
So I figured this out.
It seems at some point Reiza went through and changed FrontGripEffect to 0 for all the cars, located in the realfeelplugin.ini file.
That may be fine for finely tuned mods, but for others like the EEC mods, it isn’t. A simple change to .8 or thereabouts brings some great pulsating whenever I start to understeer.
We've improved the calculation of tire self alligning torque, which is responsible for the FFB dropping a bit as front slip angle increases. This is much better than the RealFeel 'frontgripeffect' line as that numbs all FFB as far as I recall.
However, if the FFB goes lighter, it doesn't have to mean you've reached the limit of grip. It all depends on the tire and suspension geometry. Overall, you probably expect the peak force feedback to occur before you've reached peak grip.
You could make a suspension geometry where the FFB would be almost zero when reaching max grip. FFB and grip are not directly related. Just to confuse racers and make it even harder..
