It's doubtful the SACC and EZ PS kits use the same EPAS motor as I'm told by Gerry Romack, who's driven Panteras equipped with both, that the systems feel VERY different.
I was just told that the difference in feel is not caused by the motor assembly used. It is likely in the "reprogramming" of the separate electronics control box from the original stock production application.
Dialing down the assist without a VSS can also be done by adding a torque sensor internally within the motor assembly by varying the teeth to different varying lengths that effect it's harmonics. That one is certainly beyond my realm of abilities.
There are now at least two aftermarket companies that have their programs re-written AND that at least one has an internal torque sensor which determines what speed you are traveling at WITHOUT a VSS. Just the vibrations it senses from the car in motion according to a pre-written menu.
It is done by adding an additional board into the control module.
There are several variations of the "manual control knob". One is fully manual. The second ramps down the boost according to speed no matter where the starting point is on the dial.
