Corsa Steering Controller - NO KNOBS!
Microprocessor based EasiPAS - Electric power steering assistance, EPAS controller for Corsa B or Corsa C steering columns, fitted or being fitted to any car.
This product is ready to install. All you need to do is to connect an ignition switched +12V and install your own momentary push button on or near the dash. Colour installation and user instructions available in English, French, Portuguese and Spanish. Comes complete with microprocessor based controller, connection wires, plug to connect the Corsa ECU, installation manual. You will need a (momentary) push button to match your dash style.
Electric power steering uses an electric motor to assist the driver’s steering effort. The Electronic Control Unit or ECU receives information from sensors and decides which level of assistance the electric motor should deliver to the steering you desire. Systems give more assistance at slow speeds and less assistance are higher speeds, as less steering effort is required to steer when the speed is higher.
When you install a Corsa B or C electric power steering in your vehicle it won´t work correctly because the ECU won’t have or receive information from vehicle speed and engine sensors. EasiPAS solves this problem, by giving you the lowest assistance level at all times which is sufficient for most kit cars and/or rally cars. However should you wish to park, simply press the button and you get a minute of high assistance, after which time the system will automatically revert to the normal low level of assistance.
HOW IT WORKS
When the engine is started the circuit waits 10 seconds for the Corsa EPAS to initialise, other products do not do this! During this period it sends no pulses to the EPAS. After 10 secs the circuit outputs an engine rev pulse to let the EPAS know the engine is running, if the EPAS does not get this signal it turns off to conserve power. After the 10 sec start-up delay the EasiPAS outputs for 1 minute a slow speed signal this will give you 1 minute of high assistance to manoeuvre, after which time EasiPAS will revert to the default state of high speed which puts the EPAS into the low assistance state (as if you are driving at 45+ mph). So you always have this low level of assistance.
Rather than an rotary knob our system uses a momentary contact push button, like a horn switch/button. If you press this button the circuit output goes to the low speed/high assistance state for 1 minute allowing you to park. After 1 minute it automatically reverts to the high speed/low assistance state. Should you need more time simply press again for another minute.
Power steering columns are retrofitted to many vehicles. Corsa steering is particularly popular as the columns are small and can be easily obtained at a breakers yard and online.
Typical applications: Rally cars, classic cars, AE86, Escort Mk1 Mk2, 7 Clones, Opel Manta Ascona Kadett, Westfield, Nova, Minis and many others.
Note this controller only fits Corsa B and Corsa C electric power steering columns.

) when I spotted these 16" fans on the bay of thieves , anyway they fit the rad really well and with the mounting holes being so close to the rad brackets it seems a shame not to incorporate them at the same time. So its going to be mk5 rad bracket/fan mount combo
