rFactor Better FFB Tutorial

DOWNLOAD UPDATED!! (Oct 8th, 2011)

I recently got hold of a friends iRacing account because he insisted I needed to feel this "incredible" "amazing" and "realistic" Force Feedback that he and other iRacing enthusiasts have been touting on-infinitum. I had no doubt that it would be better then rFactor's as rF's age has put it at a disadvantage. I tested with every car in the account on several tracks to get a "feel" for what the iR ffb was actually doing.

I was confident in my ability to duplicate it in rF, I spent the next week searching, tweaking, tweaking and then I did some tweaking to rFactors default Controller.ini, Realfeel and Leo's FFB.

With this concoction of a modified Controller.ini, modified default RealFeel (Thanks goes to this guy's tutorial for the original modification ideas http://www.eoaa.org/phpbbforum/viewtopic.php?t=338) and the painfully difficult editing of Leo's FFB settings. I was finally able to settle and do some testing (and more tweaking).

What this FFB will do is... Well you have to feel it. I think this feels better than iRacing. You will need to adjust every car with realfeel's numpad hotkey's, but with these settings I feel every crevice and bump in the road. I can feel the brakes lock up and the steering goes numb. A locked up tire will pull the steering wheel. I can even feel the slight pressure difference on the steering as the front of the car goes up and over hills and then gently lands again.

===TUTORIAL START================================

For all the Fanatec users, remove the PorscheWheelPlugin.dll from your plugins folder as it interferes with this!


I am using a G27 with a larger wheel than stock and used both 900 and 720 degrees of rotation for testing. Some forces may be set stronger for me than you would like but adjustment is pretty simple.

1} Download this zip. (Updated As of 100811) It contains all the plugins you need with the default settings set already. http://www.mediafire.com/?4f1r9k5oiyqbdxo

2} Move the files to their appropriate location Overwrite or remove any previous versions of Leo's or Realfeel!

3} Change the lines in your rFactor\userdata\yourname\Controller.ini There is a copy of them in the zip but I will post them here as well. http://paste2.org/p/1263317

4} Go to your Driving wheels control panel and set it up as follows. Even if you aren't using a logitech the spring, damper and strength setting should still be somewhere.

5} Change the "Front Wheel Lock Angle" line in rFactor\plugins\LeoFFB.ini

The very first line should be changed to your preferred steering lock used in "most" mods. Sometimes this won't be correct if a mod limits the angle but use an average. I use 22° if on 720° of wheel rotation and 28° if running 900° and the mod allows it.

6} Testing Once in-game you will not have to edit anything. Load a car such as HistorX or the Lotus23's or any mod that works with realfeel. I RECOMMEND USING A REAR WHEEL DRIVE CAR FOR A FIRST TEST!! When you go on track you WILL NO LONGER hear a voice say "realfeel is enabled" This was disabled in the newest realfeel. While sitting still you should find it difficult to turn the wheels and the steering wheel should stay where you turn it. This means that the Leo's is installed correctly.

** If you have severe oscillation when not moving simply lower the "Stiffness of Stationary wheels" value in the LeoFFB.ini

7} Adjusting the FFB
This is the hot key config used by RealFeel. The only things you should be concerning yourself with are the "Reverse FF", "Stronger FF", "Softer FF", "Decrease RFP mix" and "More Smooting" options.

A} Immediately in every new car you use set the RealFeelMix down to 90% (RIGHT CTRL + NUM 1) it will allow the Leo's road bump effects, rumble strips and grass effects to be felt. If you forget to do this the following adjustments will be off.

B} Drive the car at a decent pace turning back and forth. Once rolling ~25 mph you should be able to feel if the FFB is in the correct direction (Pulling to the center) or if the mod has the geometry backward (your steering wheel tries to go all the way left or right.) If it is backward you need to press "RIGHT CTRL + NUM 8". This will reverse the FFB for that particular car and you can continue.

** Note, when rolling forward for the first time around 12 MPH you should feel the Leo's stiffness fade and realfeel will take over. With some mods this transition is transparent in others there is a slight wheel shutter.

C} If the force is too strong you can use either (LEFT CTRL + NUM 9) to lower the FFB strength by 1,000 or (RIGHT CTRL + NUM 9) to lower by 100. Use NUM 7 to make it stronger. Drive for a while at high and low speeds, braking hitting rumble strips etc before finalizing this number.

If you notice your steering wheel vibrates alot when there should be no reason OR if you have to set the strength divider set under 1,000 it is recommended you use a smoothing level of at least 1 (RIGHT CTRL + NUM .)

A SPECIAL NOTE!! The RealFeel plugin's force is most dependent on the suspension CASTER of the car you are using. The higher the caster the stronger the force you will have straitening the wheels out at speed. If you find a car has severely low or high FFB. Instead of putting the Strength below 1000 or raising the divider above 8-9000 and risking over/under modulation try to adjust the Caster in the advanced tab to ~4-8 degrees. An example of Caster being an issue is the V8 Supercars use 15° of caster which is VERY HIGH. I set it to 7° and it was much easier to adjust the FFB correctly.

10} A Note on four wheel drive/ front wheel drive cars. You may find cars like the Historic Rally Cars or the HistorX Mini feel "funny". This is due to the front wheels being powered. What you will feel is, when coasting, it feels perfectly normal but when on the power through a corner the steering force will go light and even pull to one side. This is an effect known as torque steer. It is realistic for cars of this type and I have never felt it with any other FFB setup so that is a bonus.

That should be it. Now for every car you load the calibration procedure will be repeated and the adjustments will be saved automatically to your "rFactor\realfeelplugin.ini". It only takes about 20 seconds once you get the hang of it. I have included as many mods pre-adjusted as possible to help everyone with the transition. The following cars come set up by me.

Finally, Some mods simply DO NOT WORK with this FFB. I would point out the Saleen S7 Turbo mod as one. I couldn't for the life of me get that or the Mazda MX5's to feel "right". I tested as many mods as I could but if you find one that doesn't work or you are having issues, please post details here and I will take a look. Good luck and Happy Driving.
 
yep its installed just fine, everythings where it should be. I hear the RealFeel woman when I make changes so its all there.

EDIT: Quoting does'nt work on this forum very well does it?!? the above was an answer to William!
 
OK getting somewhere, I deleted the LeoFFB and just used RealFeel and it works fine, the FFB is there in abundance! A few tweaks and its much better, not sure why Leos is getting in the way for me though....thats the odd part but I can live without it.
 
yeah its weird alright, did an rFactor re-install and did the install word for word again but same results, Leos certainly screwing up somewhere but bugger if I know why, anyway deleted that for now and the RTealFeel settings feel great enough anyway, many thanks :)
 
Just wanted to pop back in and mention that I decided to try out iRacing again, after having let my membership expire a few months ago, and I think my previous perception of the superiority of iRacing's FFB was undeserved ... all it has, really, is a pretty stiff center and overall heavy feel to it, but fairly little detail compared to what can be achieved following Steven's process here. It seems iRacing doesn't even have any kerb rumble -- there's a rumble sound, but no FFB effects. And it seems like there's little in the way of FFB indication of lost grip, either. So, it's back to rFactor and LeoFFB and RealFeel for me. :)
 
3) At very low speed, up to about 20 km/h (=12 MPH), I believe Leo's FFB is in control, as you mention. In this region though, I get absolutely awful left and right violent turning of the wheel. It's nearly uncontrollable; I don't dare let go of the wheel or else it'll violently shake my entire setup. This can't possibly be how it's supposed to work, is it? Any ideas why this would happen? I tried adding Deadzone on my wheel to no effect.

I just had the exact same problem, while in rFactor, I went to look at the controller settings, scrolled through to the correct Controller.ini file, and hit load, problem solved :D

If it doesn't work, you could edit the "FFB steer force neutral range="0.00000" // Max distance from center "neutral force" location where forces are reduced to help avoid oscillation (0.0 to disable)" line of your Controller.ini to reduce the force near center and prevent oscillation, 0.04500 is the default.
 
Hi all! I have a LOGITECH DRIVING FORCE GT...
I'm playing ENdurance series and i have real feel and leo's ffb...
When i'm in the garage, the wheel goes to full rotation and if i try to correct it, it goes all the other way to full lock, i mean either the car (0mph) is at -135º or +135º... i play with 270º
What paramater should i change??

17.5 Front Wheel lock angle, degrees (max deflection to one side from straight on)
0.81 Front wheel distance to centerline (half the front wheel track) in metres, from .pm file
1.36 Front axle distance to body reference point (about half the wheel base) in metres, from .pm file
1.2 Relative strength of FFB effects
10.0 Aligning moment curve shape / feeling of tyre losing grip. Lower numbers are duller, range 1.0 .. 10
0.99 Negative aligning moment parameter for high slip angles, range 0.0 ... 1.0
9.79 Slip angle where aligning moment reverses direction - typically between 8 and 15 degrees
3.8 Caster (dimetionless)
0.0 Camber ratio (not degrees!)
1.0 Road bumps feeling on the wheel
11500.0 maximum FFB force for stationary and low speed effects
12.0 stiffness of stationary wheels
1.5 wheel rubber hardness (1..5)
7.0 how quickly static forces drop off when rolling

the car's a bmw gtr addon, but i tried 997's leo and also gos to full lock

Any help would be really nice! Thanks in advance!
 
Your realfeel is backward. if your on the track moving forward does the wheel center properly?

Also 270° may be too short a throw for these forces to translate properly. If you can raise your in-game steering lock on the car you can use a more reasonable amount on the actual wheel. For example if you have in-game lock of 15-17 and 270 on the wheel. Then you can go up to 500 on the wheel and use 25-30 steering lock.
 
Ive tried this setting...everything seems ok...except that i cant feel it when i brake.
Driving the enduracers gt2 f430.

Well you shouldn't feel anything in the steering when you brake unless you lock up and start to skid, the FFB would go light. Vibration would/should only occur slightly if traction control was on but really that isn't realistic.

And I wish m able to control my slide like in iracing and netkar. I cant do it with rfactor ffb tho.

Depends on the mod. Enduracers are not known for their FFB Translation.
 
Exactly as Steven says, the only feel you would get in a race car is through the brake, and depending on the car, you may get a "shove" effect on your body as the car either kicks out it's rear or front (mid corner).

As for being able to control sideways motion, it can only be done to the same level as in real life with a £25,000 simulator, I'm not sure if the cheaper ones can give the same feel, but even at those kinds of prices, you still lose too much feel to call it realistic feedback.

That being said, the only reason iRacing, LFS and netKar allow you to control the slides, is the cue given by vision and sound is much greater and earlier than on rFactor. This enables you to see and hear the snap before it happens, therefore allowing you to switch lock and continue on, this is not FFB, just clever programming. To prove it, why don't you go about sliding in one of the mentioned games, and switch lock before the snap is indicated, you will find the FFB responds exactly the same.
 
Yes. I think so too. Its not just abt the ffb. You got something going on here Steven. Ive been playing rFactor all these while and only recently when ive lost all my settings due to corrupt hdd that ive been on a lookout on new settings. And I loved how iRacing feels and its great that youve found a way yo do that with rFactor :)

Im gonna share this find with my league mates :)
 
Thanks Steve. I didnt replace Leo's dll and ini with urs apparently. And the Realfeel i had was the old one.

Im having so much fun with it just now. I cant get to my normal pace coz familiarizing with 17deg FOV and the head movement. Plus 24 steering lock on 900 deg rotation all on my 1 month old triple screen rig.

Well i guess its time to learn something new :)
