I've always thought there are two schools of building a simulator FFB engine:
1. Just simulate the real FFB effects on the steering column.
2. Mix in a bit of "seat of pants" car feel, for those without a full motion simulator
Every sim tends to pick one or the other. Only pCARS and Raceroom seem to allow you to mix in and out the "seat of pants" elements. I've not seen anything in AC which would allow that, certainly not in the UI.
Yeah, and I got a great FFBTweaker made that does number 1 really well. It was so enjoyable, and the next day they overhaul the system and they don't work any longer. *grumble*
So now I am waiting till those features are in the pCARS GUI/menu.
Personally I don't have a motion simulator, but I just can't play well with the seat of pants effect. I know better what the car does front to back with just "real FFB effects on the steering column".
Maybe it's because what I am used to in my car, so it's easier to relate to and I have a better proprioceptive memory (muscle memory) with that system.
Also the Force Feedback loop present in steering wheel controllers where the FFB motor directly influences the position sensor, that loop causes the Physics to be thrown out of whack.
As every FFB effect executed causes some change in direction, it has direct influence on the weight transfer within the car. Which has direct relations to everything else.
Hence I prefer what comes through the steering column as that's what the car is doing, and thus has no negative effect on the way the car handles (no negative effect on the Physics).
And it's quite possibly the same reason why some people still prefer a FFB-less wheel. At least I heard something like that being mentioned during an ECCI review at ISR in the good old days, that some people still prefer either a G25/27 or DFGT or a FFB-less smooth ECCI for some reason. Which I think the above might be one of.
Iirc there will be ffb update too in the next release, unless im mistaken(?).
So maybe check again after it's out.
Haven't driven AC or anything for that matter in a long time myself. Maybe time to check it out again.
There seems to be improvement for sure.
The Alfa Romeo Guillietta drives like my Lancia Delta HPE (which is Alfa 155 based), at least Physics wise. FFB wise it's close, but could improve still.
The rumble when you overturn needs to come in stronger, the road noise needs to be less, and the peak of the slip curve is noticible but the fall-off should be felt a bit better.
The FFB really improved though. I just use 60% gain, 0% filter, 0% Damping, 0% Kerb, 0% Road, 0% Slip.
