MCC can actually be a lot lower than MMC, no issues. And mechanical time-constant is anyway dependant on servo, and a variable inside the IONI/Argon setup parameters, has been there since day 1.
So it can be set to whatever is specified by servo-manufacturer.
Wrt the Simagic wheel, most, if not all, plus then some, filters are already covered by Simucube2. They use different naming conventions.
Like said before, there’s a reason SC2 is the flagship dd wheel, it will be a while before it will be dethroned. I have commented before that we are truly at the pinnacle dd wheel engineering with this, next big steps to significantly improve ffb will have to be in moving away from Microsoft DI and doing custom driver API.
Also, where iRacing is concerned, there needs to be development wrt 60hz ffb signal. But that is another topic for another day, imho, even with the low update rate, it’s ffb is still better than any other candidate sim out there.
