How to know the in-game steering force

    Hi,

    I would like to know, if possible, the in-game steering force in Newton Meter, to make a comparison between the curve and peaks of my steering wheel and the real cars. Maybe with MoTec or with any other program? Many thanks.

    The torque in Nm depends on your wheel.
    A G27 for instance has max torque around 2Nm...
    So nothing to reach real torques.

    Yeah, I would like to know the percentage of DD wheel torque force setting corresponding to a 7/8 Nm ok peak.

    DD bases are around 15 to 30 Nm
    Depends on base.

    For my DD2 to average this torque it would be something like 35-40% FF for the wheel driver and 70% gain in game.

    Finally, I found a YouTube video where we can be able to adjust our SC2 wheels. The DD2 has 25 Nm of torque peak, the same as my SC2 Pro, and when he puts 35 % of force strenght it corresponds to 10,7 Nm of torque peak. I think that a GT3 car doesn't reach 10,7 Nm but 7 or 8 Nm, so I only have to decrease the percentage a little (doing some calculations) to configure the SC2 True Drive setting to that. I hope this video will be useful for all SC2 owners and thank you for helping.

    If you can tell me how much percentage of your DD2 wheel corresponds to 8 Nm of ACC peak I will appreciate that (this could avoid some calculations :D).

    Sorry I didn't understand your request. Can you please elaborate what you mean..?

    The video that I posted shows that with 35 % of FFB gain in ACC, the DD2 reaches 10,7 Nm of force peak. Then, I would like to know how much percent of ACC gain I must put for the wheel have to reach only 8 Nm and not 10,7 Nm, because I think that the real GT3 cars reach 7 or 8 Nm and not 10,7 Nm. Sorry for my bad English. :p

    PD: Other problem that we have is that the real GT3 cars have power steering, and I think that the ACC doesn't simulate this thing, so we can simulate the max torque peak but I don't know if we can simulate the real steering force (with power steering) maintaining the same 8 Nm of max torque peak.

    Use rule of three for this easy calculation.

    35% equals 10.7Nm
    x% equals 8Nm

    Okay, I was dubting if the rule of three would be the correct operation jeje Yeah, the result is 26,16 %, so I have set 26 % in the ACC gain. Thank you. I hope we'll solve now the power steering problem... :D

    But what you forgot to consider is the mass and diameter of your rim.
    This influences of course the torque you have to apply.

    In my opinion is more important the influence of the power steering (I'm quite sure that a power steering can variates a lot the strenght of the steering wheel forces) than the influence of the mass and diameter of the rim. I don't understand exactly what you mean, because 8 Nm is enough force to invalidate any mass or diameter of our rims I think... But anyway, the diameter and mass of my rim is similar to a real racing car rim also...

    PD: I don't mean the torque that I have to apply but the maximum torque force that reaches a real GT3 car, even if my arm is a piece of paper. :D

    I didn't watch the video.
    But if they measure the torque in the real car at the rim, then you have to do the same. If you adjust the torque of the base at 8Nm and attach a rim for a truck, you need to apply much less torque than attaching a small F1 rim.

    Obviously my rim is smilar to a race car not to a truck, jeje.

    Talking with a friend, maybe we don't need more modifications because when we adjust the 8 Nm torque peak of a GT3 real car (with power steering) it means that we are already adjusting our wheel to a steering force with power steering...
