Before you start getting excited unpacking your brand spanking new wheel and fire up rFactor straight away to drive at any track and ended up getting disappointed in the end, your wheel must first be calibrated. Your wheel is design in a clever way that it can be calibrated and refined to produce the proper feeling of driving a car. This is so important if you want to get the maximum out of your drive. A properly calibrated wheels convey force feedback that will relates motion, weight, available grip and bumps in a manner that will help a driver calculates his next course of action.

After unpacking and attaching your wheel, you need to install Logitech Profiler Software which is provided with the wheel or can be downloaded on the net. If you are using different wheels, maybe you can relate to the figures since the setting parameters for every wheel are almost identical.

The next step is to fire up the Logitech Profiler  

As for the degrees of rotation, Momo user will have it at 270 (since it's the maximum figure for momo), G25 users may have it until 900. It's up to the mod. For Enduracers mod, G25 users might want more resolution available to them, hence 500 degrees of rotation is a sweet spot. The more resolution (higher degrees) that is available to you the more refined the input from the wheels to the software even though you seem to be a bit aggressive on the wheel. It's very useful when recovering from a big slide or sudden snap oversteer. It's also a lot easier to place your car very precisely where you want and thus results in consistent lap times.

But why 500? why not 900? Good question.

You don't want to have too much resolution in actual steering as well. There is fine line between too much turning angle and too little. Since the reaction times require to steer some car (for example, a F1 car) is minimal, you don't want to find yourselves turning the wheel twice to negotiate a bend. That will cost you a lot in terms of lap times. If you happen to watch a real life race driver negotiates a bend, look carefully, they never have to take off their hands and go for another rotation to the wheels when negotiating a turn. At most, their arms will crossed.

Before I begin, ffb and force settings is a matter of personal taste. It's how you teach your muscle to identify what certain forces mean and how to react to it. Perhaps at first, it will be quite awkward to switch to something new. But for those only beginning with realfeel, this guide or my settings actually, which is my preference might be of a help to you.

Next is the in game settings

Note that im on a full force feedback effects, with low forces you will experience realfeel alone without a mix of ISI ffb interfering when you run over kerbs. This is good, but for me immersion wise it's quite dull on me. So how do I solve it, by setting it to full alone will not help, because the rumble strip effect in the controller.ini settings was too harsh too begin with if I set it to full. Hence I edit the controller.ini with settings from GTR2. I like the way GTR2 tells me which are the kerbs and which are the nasty bumps. I attach a CONTROLLER.INI settings for you to replace to yours in user data, your user name folder.

For example:
C:\rFactor\UserData\muaz\

Inside here is the current controller.ini, replacing it will overwrite default ISI ffb with my ffb. This will adjust the rumble strip effect in your game. I favor these setting, you might want to try it. But first do a backup of your folder first.

Then

The rate is pretty much at default.

Last step is to take my realfeelplugin.ini or either you take the number inside and put the figure by yourself or replace your .ini with my .ini.
