Description
Standalone electric power steering controller kit for Opel Corsa B and C EPAS steering columns in motorsport applications.
This electronic controller kit is engineered to operate the electric power steering (EPAS / EPS) steering columns from Opel and Vauxhall Corsa B and C models. It is designed for circuit racing, rally, drift, autocross, and custom retrofit projects (such as Ford Escort Mk1/Mk2, classic Opels, Minis, and kit cars) where an electric power steering column is fitted.
The original Corsa steering ECU requires vehicle speed sensor (VSS) and engine speed pulses to activate power assist. Without these signals, the factory controller remains in a failsafe state without assisting. This module emulates the necessary communication signals, allowing the steering column to operate standalone in any vehicle chassis. The included cockpit-mount rotary potentiometer enables the driver to continuously adjust the level of steering assistance to achieve the desired steering feel and road feedback.
Features:
- Operating Principle: Emulates factory speed and engine RPM signals, enabling standalone EPAS operation.
- Assist Adjustment: Continuous manual assist control via a cockpit-mounted potentiometer.
- Wiring: Pre-wired harness with the factory-style ECU plug connecting directly into the steering column ECU socket.
- Power Supply: Connects to vehicle switched +12V ignition power and chassis ground.
- Applications: Circuit racing, rally, drift, kit cars, and custom classic vehicle retrofits.
Important Installation Notice:
Main Power Supply: This controller kit operates low-current signal circuitry only. The primary high-current power cables supplying the steering motor and ECU must be wired directly to the vehicle battery using heavy-gauge cables and an appropriate inline fuse (typically 50A rating).
