hi, please download and read the instruction file in this topic,
http://www.reasnow.com/forum/index.php?topic=1517.0 And pay attention to page 8 especially.
for Forza 6, you should use Forza 5's config, but it will only work in Legacy Mode,
in this Mode, your wheel will not be synchronized with the wheel in game,
and the H gear can only be used as suquential shift.
