Important
Mapping of the look-up tables has to be done, when maximum possible steer angles can be achieved. Has to support
maximum achievable voltages between neutral and right most as well as between neutral and left most. Add some
tolerance. In most cases this voltage will be asymmetrical, and base voltages should be so as well, for maximum
precision. If sensor gain is changed lookup tables are invalidated

The sensor characteristics needs to be mapped, according to Figure . The cylinder stroke volume @ 33% (P3815), 67%
(P3817) and 100% (P3819) of the voltage base (P3821) should be mapped, where voltage base is:
The absolute voltage [mVolts] from the WAS, going from neutral to left most position, when maximum possible steer
angles can be achieved on the vehicle + some tolerance.
