Thanks for explaining a little of the how the calibration is coded. I  
think I can see how that ties into what I am seeing. Responce like a  
chopped off parabola. With the values I gave it, a broad dead zone then  
very steep rise.

Yes , the mouse is the same, so it's not an external joystick util  
interfering here.

In fact, mouse steering is a better way to see the effect because you can  
have the mouse pointer over the nose of the car and the extent of the dead  
zone is a lot more evident (although you can't put any numbers on it).
It seems the basic problem is that we need full lock to recover from a  
skid or crash but most of the time very limited steering.

Joysticks , even plastic steering wheel types , only have a very limited  
movement. Real cars probably have two full rotations of the wheel.

This probably means some trick has to be found which deviates from correct  
modelling of a car.

Could you point me to where this is coded? I'll experiment a bit and see  
if I can get something that works a bit better.

Thanks again for your help.
