While configuring my new FF wheel I "discovered" the "steer_ratio" option in core.ini. When it is set, the default, then you get extra wheel output at low speeds. This seemed to be definitely not simulation, so I turned it off. I immediately had to lower the ratio to a most 13:1 to be able to drive in the pits and around sharp hairpins. This, of course, affected driving, but it wasn't too bad even with only limited non-linearity. After a while I got used to it. Now to my question. While testing different ratios I noticed that *visually* the wheels only turned until the inner wheel was lined up with the drivers line of site. This is as it is in a real car. Lowering the steering ratio even more just meant the you hit this limit earlier. Does this *visual* limit correspond to the effective limit? I.e. can I use set my maximum steering ratio checking that I get full turning on the the steering wheel and front wheels? This limit would *visually* seem to be araound 12/13:1. If this were the case then using a setting below this would not give you MORE steering, it would just mean that you hit the maximum earlier. Robert P.S. I love the FF wheel. Not much for what I expected to feel but for the feed back from the car. You can feel the rear-end swaying. -- Robert Virding Tel: +46 (0)8 545 55 017 Alteon Web Systems Email: [email hidden] S:t Eriksgatan 44 WWW: http://www.bluetail.com/~rv SE-112 34 Stockholm, SWEDEN "Folk s�ger att jag inte bryr mig om n�gonting, men det skiter jag i".
I have just found the answer to my question. The main straight at Monza is wide enough for testing so I did some experiments. Using a smaller ratio, like 8:1, gives a smaller minimum turning radius than a larger ratio, like 12:1. I am experimenting with 10:1 to give enough turning but not too sensitive. I am not completely linear, this is too compensate for my wheel not being able to turn as much as a "real" wheel. Robert In article <3b276822$[email hidden]>, [email hidden] (Robert Virding) writes:
