Is there any way to remap the reserved keys such as ignition to my MOMO wheel?

If you are using the Wingman Profile program, you can map a button to a key and control any key press from a button on your wheel.
Another option for mapping buttons to keys is JoyToKey http://www.electracode.com/4/j ... y%20English%20Version.htm (I can't get the page to load now. Maybe the server is down).

Thank you
