That is incorrect. The strength setting on the wheel base sets the torque range available to the wheel. In GT7 you set the actual output of the torque and then it utilizes the resources you've allocated from the base. Setting it to 11 on the base gives it the full dynamic range the wheel is capable of.
Setting to 7 on base and 7 in game is not the same as setting it to 11 on base and 7 in game.
Game torque does indeed set the max possible torque output of the wheel and setting the in-game torque to 7Nm means you then have 11 graduations on the wheel, with 11 being the 7Nm max that you set in-game. Whilst that is true, it is important to know that, upon loading GT7, the wheel strength setting is COMPLETELY IGNORED unless you physically alter it on the wheel.
'Setting to 7 on base and 7 in game is not the same as setting it to 11 on base and 7 in game.'
This statement is correct, but only if you set the 7 on the base AFTER loading GT7, then the wheel will output 7/11th's of your 7Nm max. If you just load the game and don't alter the wheel, you'll get the full 7Nm that you set in-game.
For example... set your in-game torque to max and wheel strength to 1 and quit GT7.
Now load GT7 and play a game without touching your wheel strength setting.
The wheel will now output a full 11Nm despite your 1 setting on the wheel.
Now, with GT7 still running, manually change the wheel setting to 2 and your output torque will go straight from 11Nm to 2Nm, because the wheel is now overriding the game setting.
Potentially, you could leave your wheel at 1 and you will still have the full 1-11Nm range available in GT7 settings (as long as you don't touch the wheel setting).
The only advantage to how this works that I can see is if you don't ever want the wheel to output the full 11Nm, you can limit it in game and still adjust on the wheel within that limit.
Otherwise, you can either ignore the wheel setting altogether and only ever adjust torque in-game from 1-11Nm, or, set the in-game to max and do all your adjusting on the wheel (remembering to adjust it by at least 1 point on the wheel directly after GT7 loads up, or GT7 will ignore it).
I'm fairly sure that
@LOGI_Rich would confirm all this.
