Hello...i'm new around here...

because i was charmed by this game i bought a steering wheel (genius twin wheel f1)...
but i have a problem with pedals...my accelerating pedal is not working corectly...by this i mean that is not taking full acceleration...just half of it and my car is bearly accelerating....

what can i do about it?

sorry for my english...i'm not a native speaker!!!

It seems to me like some sort of problem with combined/separateed pedal axes.

Try the diferent options in LFS and Windows and check if that solves the problem.

If Whiskey's suggestion won't solve it you can try to check if the accelerator pedal is fully calibrated in axes.

Press CTRL+C. Go to options > controllers > axes.
Press the accelerator and see if the yellow bar corresponding to the accelerator-axis moves accordingly.

Have a look in the LFS Manual and see if any of that info is helpful;
