    Hi Again,

    I hope this is ok to start another thread separate to my previous.

    I have used the following website to help convert some OLD 2001 f1 cars over to rfactor 2.
    http://meetme.bplaced.net/rF2_onlineTools/

    Everything has imported fairly well, but i have had problems getting steering correct with Rfactor 2 method.
    Can some shed some light on the below lines and help get correct figures for f1 cars. i am mainly after what is correct turns to lock for an f1 and the steering ratio. as i believe the tools has assumed incorrect figures?

    Below is what has been converted out. but the cars feel completely off with these values.
    I have reverted to Rfactor 1 values and gestimated figures which give better results, but i would like to use the new method and understand correctly.

    from looking below i can understand some values, eg. 360"deg turning gives me 11.5 steering angle a 1 full rotation and so forth.

    Common theory seems to be F1 has a lock of 360, but I'm sure its somewhere in the region of 540. but as for ratio, i have no idea.

    [CONTROLS]
    NominalMaxSteeringTorque=10 // my understanding, lower values give stronger feeling.
    TurnsLockToLock=2 // obvious how many rotation to lock, but what should an f1 range from. 1.25?
    SteeringShaftBaseLeft=(0,0.119888,-0.78) // ?
    SteeringShaftBaseRight=(0,0.119888,-0.78) //?
    SteeringShaftAxis=(0,0,-1) //?
    SteeringInnerTable=(0.19828,0.113,-0.78):(-0.11172,0.113,-0.78) //?
    SteeringInnerTable=(0.11172,0.113,-0.78):(-0.19828,0.113,-0.78) //?
    SteerLockCaption="WHEEL RANGE (LOCK)"
    SteerLockRange=(23,0,9) // 9 steps 0 - 23 steering angle.
    SteerLockSpecial=(0,"240","(7.7) deg","TurnsLockToLock=0.66667;SteeringFraction=0.333333")
    SteerLockSpecial=(1,"270","(8.6) deg","TurnsLockToLock=0.75;SteeringFraction=0.375")
    SteerLockSpecial=(2,"310","(9.9) deg","TurnsLockToLock=0.86111;SteeringFraction=0.430556")
    SteerLockSpecial=(3,"360","(11.5) deg","TurnsLockToLock=1;SteeringFraction=0.5")
    SteerLockSpecial=(4,"380","(12.1) deg","TurnsLockToLock=1.05556;SteeringFraction=0.527778")
    SteerLockSpecial=(5,"450","(14.4) deg","TurnsLockToLock=1.25;SteeringFraction=0.625")
    SteerLockSpecial=(6,"540","(17.3) deg","TurnsLockToLock=1.5;SteeringFraction=0.75")
    SteerLockSpecial=(7,"630","(20.1) deg","TurnsLockToLock=1.75;SteeringFraction=0.875")
    SteerLockSpecial=(8,"720","(23) deg","TurnsLockToLock=2;SteeringFraction=1")
    SteerLockSetting=8
    SeatRangeLongitudinal=(-0.1,0.1) // Eyepoint camera longitudinal adjustment range
    SeatRangeVertical=(-0.1,0.1) // Eyepoint camera vertical adjustment range

    You need to do your research? Im sure if you try hard enough you will be able to get your values from watching videos, use monaco, they use full lock there. But as to steering ratio, who knows

    yeah I have done a bit if research but nothing seems in official words.
    I have seen a steer ratio of 12:1 and 540 mentioned for open wheelers. But nothing is concrete. Videos aren't really accurate. Sure you maybe able to guess how many degrees. But how can you calculate steering angle from a video?

    I did just come across this however.
    Official F1 site. https://www.formula1.com/en/latest/...i-sf15-t---monaco-steering-modifications.html

    "For the Monaco race teams therefore modify the steering angle from the norm of around 14 degrees to somewhere nearer 20. In order to do this both the upper and lower suspension wishbones must be cut to avoid contact with the wheel rim, as you can see in this Ferrari drawing."
