Default Finetuning the FFB

I can't believe iRacing banned you from their forums and didn't hire you
as head FFB tester.

Thanks.
Although I don't know when somebody tries to be sarcastic or not.
I've been through so much bad times with this, everybody, I mean really
everybody ****ed on me, and iRacing backed up that ****ing pretty openly.
Actually, iRacing was the main problem here.
First, I don't know if you managed to do something with reading this
post of mine. There are some preliminary problems. First you have to
calibrate wheel properly. Turn off your virus protection, use Logitech
profiler, calibrate wheel so that the middle is at 8191, and left is exactly
900 (for 900 setting in Logitech driver), turn on linearity, before you
calibrate you have to work all axels few times, uncheck "Allow game to
adjust settings". You have to calibrate all axels every time you turn on
computer (from cold start). I believe that is all.
I had problems with Papyrus (the company that iRacing came from)
since the days of Nascar 2002. They have "their own" system of dealing with
FFB. I don't know where from this system is coming, but it includes not
using the damper. Because they got the impression that damper is "canned".
Obviously, they heavily rely on unlinearity, because they think that this
boosts up the tiny forces, or something. They generally boost up everything.
Dealing with unlinearity was a big problem for me, since
unlinearity, probably because of the very nature of unlinearity, changes the
way FFB is working with the change of FOV. This is probably just because of
the nature of linearity, nothing else, and it clearly shows why unlinearity
is not good.
This is such a simple thinking, and the guy that is responsible for
FFB in iRacing just doesn't do his job properly. This is thinking very
fastly, and very wrongly. In a fast race to achieve, I don't know what. You
first have to put basics right, then you have to build on it. The
foundations have to be right.
Paradoxally, everything else in this company is just right. They
have very clean graphics, excellent network code, excellent approach to
simulation, excellent organization of races. Only FFB approach is all wrong.
To make things worse, for who knows which reason, they are actively blocking
any other approach to FFB (or at least, this was the case untill now). I
mean, FFB isn't their product, they don't know nothing about it, yet they
push only their wrong approach. They had problems with this in the past,
when they dissabled damper in N2002, this was the last thing they did,
because they ceased operation after this. With iRacing, when they dissabled
damper, it lasted for only one day, presumably the response of customers was
very negative, and the very next dat they turned damper back on, and
appologized to people. Why, oh why, what is the reason they are doing this,
I simply cannot understand.
I am reasearching FFB for the last 10 years (ok, I had a brake for 5
years), and it looks like my problem was that I used only their products for
this. Because of unlinearity, which is very bad thing, I couldn't make any
progress. I knew that something is wrong, and that there should be the way
to make it right, only I couldn't do this with unlinear FFB. It was me who
discovered that something is unlinear, on this very news group. In the next
build iRacing allowed linearity. Since then things went better. But again
there was a problem. The slack. Obviously, you get rid of slack by adjusting
in-game Strength and Damper, but iRacing had locked Damper. The slack was my
main problem, and I couldn't get rid of it with locked Damper. And since
they unlocked it, I finally could fix that. Now everything is alright, but I
still didn't have time yesterday to find the right Centering Spring. To be
absolutely sure I will have to test all 150 positions (this is the way I am
working, you simply have to be sure). This month I will probably finish all
this.
