interesting how you are going to do that as "assistance" level is preset in the EPS control unit and is not adjustable as its tied in with the torque sensor inputs, as torque required drops, "assist" is reduced
Only possible way I could think of doing it is to interrupt the torque sensor inputs but they are a proportional control and react like a piezo element, more you turn against the force the higher the output gets from them.
Watch the electronic PDM's, these can give all sorts of funny issues depending on how they are set, some try to clamp close to current limit with all sorts of noise generated. If your cuts off cleanly then you shouldn't have any issues. I have my doubts, those EPS units can pull some big currents momentarily (well over 70A) and the PDM might treat that as a fault where a fuse wont. Add a bit of hysteresis in if you can to allow for that momentary spike as the motor fires up.
