There obviously is a bug preventing the left pedal to be used - under normal
circumstances.
You will usually have the Virtual Pilot configured and calibrated under
Windows95. This perfectly works with most or all games. Unfortunately, F1 by
Ubisoft will no recognize the Pedals as Joystick No. 2.
Thanks to (if forgot his name and the site is down, so I can't look it up),
who published the crucial hint on the web page
http://www.racesimcentral.net/, there is a way to work around
that problem though this cannot be the final solution.
You have to define the Virtual Pilot (or whatever device) and the CH Pedals
as two different joysticks under Windows95. This seems to work only, if you
choose two times "2-axis/2-buttons" joysticks and calibrate properly. Be
patient, you may have to try this several times.
Next time you start F1, go to the "configuration-menue" and the pedals will
be recognized as a second (or first) joystick.
Have fun and thanks again to ...., who found out!
