Yep cool
however still not tuned noting;
Adjustable potentiometer to simulate variable speed sensitivity.
Wheelspeed input can be added to make system speed sensitive.
It is DC analog servo with worm spur gear drive. The drawback it is not a digital control as in stepper or the like in Pulse level and Frequency it is voltage and current best I can tell.
I have not driven a car with electric steering, however my plane has a pneumatic analog autopilot, the feedback is not like driving, there is none except for vestibular.
I have used in robot control both stepper and servo. Stepper is much better for fine control and tuning. Servo can do much more as in torque heavy load values yet much harder to tune with analog technlogy.

Products - Electronic Power Steering
DC Electronics have developed a fully integrated stand alone power steering system for both competition and road use.
Benefits:
- Small compact unit, requires only a battery connection to work.
- No messy hydraulic connections or systems to bleed.
- Weight saving advantage over hydraulic systems.
- Reduced mechanical drag on engine compared to hydraulic engine driven pumps.
- Adjustable potentiometer to simulate variable speed sensitivity.
- Wheelspeed input can be added to make system speed sensitive.
- Built in fail-safe which allows the system to revert back to the conventional steering
in the unlikely event of a fault occurring.
How it Works:
The system replaces the existing steering column.
An electric motor and torque sensor are fitted in-line with the steering column. The torque sensor monitors the amount of force applied by the steering wheel. This signal is then fed into the EPAS ECU where a calculation is made allowing for the off-set from the variable potentiometer. The appropriate amount of assistance is then delivered by the motor to power the steering rack.
