I'm using a logitech extreme 3d pro joystick. Autoshift works fine in single player,but not in multiplayer. I can't shift out of second when leaving the garage-- seems like there is a pit limiter speed on-- maximum speed is 48mph. Sometimes when starting a race from the grid it works?? Anyone have a suggestion how to fix. Great game otherwise.

Pressing "L" in multiplayer turns on/off the pit speed limiter

Alternatively you can bind the pit limited to your controller of choice (recommended if you have the button to spare)
