Logitech Profiler is a program for Logitech controllers (including wheels).
http://support.logitech.com/en_us/product/g27-racing-wheel#downloadIt allows you to have different wheel settings for individual games (or emulators).
It detects when the exe is running and changes the settings automatically.
Most old games require you to have the pedals marked combined in Windows (under controller settings accessed by right clicking the controller under windows devices, but it's different for different versions of windows).
Profiler will allow you to have different settings for each game instead of just using the settings in Windows.
You'll have to create a profile, point it to the exe, and then customize the settings.
It's been years since I messed with it, but I'm pretty sure the setting for combined pedals is under "Specific Game Settings"
FYI, Model 2 emulator requires you to have the pedals marked separate.
