Wisefab WF779 EPS (Electric Power Steering) control module. Lets the factory electric steering rack from the BMW E9X/E8X operate stand-alone, without the rest of the donor car's control modules - commonly used when swapping an EPS rack into a project/drift car. Offers three selectable power-assist levels to tune steering effort/feedback.

Fitment: BMW 1 Series/3 Series - E81/E82/E87/E88/E90/E92 electric power steering racks only (N52/N43/N46-equipped cars with EPS from factory); does not work with the E89 Z4 rack.
