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.<\/p>\n<p>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.<\/p>\n<h3>Features:<\/h3>\n<ul>\n<li><strong>Operating Principle:<\/strong> Emulates factory speed and engine RPM signals, enabling standalone EPAS operation.<\/li>\n<li><strong>Assist Adjustment:<\/strong> Continuous manual assist control via a cockpit-mounted potentiometer.<\/li>\n<li><strong>Wiring:<\/strong> Pre-wired harness with the factory-style ECU plug connecting directly into the steering column ECU socket.<\/li>\n<li><strong>Power Supply:<\/strong> Connects to vehicle switched +12V ignition power and chassis ground.<\/li>\n<li><strong>Applications:<\/strong> Circuit racing, rally, drift, kit cars, and custom classic vehicle retrofits.<\/li>\n<\/ul>\n<h3>Important Installation Notice:<\/h3>\n<p><strong>Main Power Supply:<\/strong> 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).<\/p>\n<h3>Package Includes:<\/h3>\n<ul>\n<li>1 pc controller module<\/li>\n<li>Pre-wired harness with steering column ECU plug<\/li>\n<li>Cockpit-mount potentiometer with control knob<\/li>\n<li>Wiring and installation diagram<\/li>\n<\/ul>\n<h3>Technical Specifications:<\/h3>\n<ul>\n<li><strong>Operating Voltage:<\/strong> 12V DC<\/li>\n<li><strong>Control Mode:<\/strong> Signal emulation with analog potentiometer input<\/li>\n<li><strong>Compatibility:<\/strong> Opel \/ Vauxhall Corsa B and C column EPAS units<\/li>\n<\/ul>\n<h3>Compatibility:<\/h3>\n<table width=\"100%\" cellspacing=\"0\" cellpadding=\"2\">\n<thead>\n<tr>\n<th><strong>Make<\/strong><\/th>\n<th><strong>Model<\/strong><\/th>\n<th><strong>Steering System<\/strong><\/th>\n<th><strong>Application<\/strong><\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Opel \/ Vauxhall<\/td>\n<td>Corsa B (&#038; Tigra A)<\/td>\n<td>Column EPAS<\/td>\n<td>Factory or standalone motorsport retrofit<\/td>\n<\/tr>\n<tr>\n<td>Opel \/ Vauxhall<\/td>\n<td>Corsa C (&#038; Combo C)<\/td>\n<td>Column EPAS<\/td>\n<td>Factory or standalone motorsport retrofit<\/td>\n<\/tr>\n<tr>\n<td>Universal<\/td>\n<td>Classic, rally, and kit car builds<\/td>\n<td>Corsa B \/ C EPAS column<\/td>\n<td>Standalone power steering conversion<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Standalone electric power steering controller kit for Opel Corsa B and C EPAS steering columns in motorsport applications.
