OpenSimWheel has been a true step forward regarding to immersion but many of us without real racing experience guessed from the beginning high end top configurations running 20 nm peaks would be unrealistic.
I used my instinct, karting and MTB experience to find values that could match what I expect to feel from a non assisted race car wheel while being able to opposite lock fast and with confidence. Remember what the great advantage of Direct Drive wheel is, fast input-output and precise response and definition while strength and stiffness are advantages to help with main features. Here we have more comments about the current state of the OSW from a real race car driver.
“I know this is a commonly discussed topic, but I have some comments add questions.
I drive a real world race car and here are some of my observations:
Obviously, all these can be adjusted with software because clearly OSW hardware can do it. It is amazing piece of work
Any input on tuning the steering is appreciated. I have a system sourced from Joe Sullivan: Small Mige (doesn’t feel that small) and IOni and all that and whatever Joe said good!!!
Thanks guys”
Among many responses referring to damper effects configuration, David Tucker replied:
“Two things you can play with.
– Our setups are not tuned by people with crazy strong wheels, it could be you need to add in more/less caster or tweak things in some other way to maximize the feel and minimize mechanical steering. I confess I have only lightly fiddled with this and don’t have any pointers on how to make a car feel more real.
– We only model rotational forces on your wheel, while in real life the wheel telegraphs vibrations from the car chassis to your hands as well. You need a tool like simvibe to bring those vibrations back into play. In particular almost all the forces you feel from rumble strips are vibratory and not rotational so that is why they feel weak without a shaker or motion platform.”
Caster is the key element to minimize steering strength effect while preserving rest of the benefits of your current setup. Try to play with it to understand how you like it.
More input from our driver:
Remember what caster angle was:
“Improper adjustment will result in steering inputs required both into and out of a corners, resulting in a car which is difficult to keep on a straight line. Too much caster (positive caster) and the front of the car will understeer more, too little (negative caster) and you will get oversteer handling characteristics.”
