Ultimate Power Steering Company Director Warwick Hutchinson comments: “We are delighted to be working with DC Electronics as a distributor of their products. They have an excellent reputation within the motorsport industry and we are looking forward to generating some excellent results.”

What are the benefits and how does the Electric Power Assist Steering work?

How it works

  • The EPAS system is installed into the existing steering column.
  • An electric motor and torque sensor are fitted inside with the steering column.
  • The torque sensor monitors the amount of force applied by the steering wheel.
  • This signal is fed into the EPAS factory ECU where the motor delivers the appropriate amount of assistance to power the steering rack or box.

Benefits

  • Small compact units, requiring only a battery connection to work.
  • No messy hydraulic connections or systems to bleed.
  • Weight saving advantage over hydraulic systems.
  • Reduced mechanical drag on engine compared to hydraulic engine driven pumps.
  • Built-in fail-safe which allows the system to revert to conventional steering in the unlikely event of a fault occurring.

We Stock (EPAS) systems that have been developed by Ultimate Power Steering and DC Electronics.

These systems are available for Motor Sport applications in a few different levels.

This system can be mounted anywhere between the steering wheel and the steering rack or steering box. The torque sensor is within the motor/Gearbox unit. The Steering Column is driven by an Electric Motor & ECU a Signal Generating Unit (SGU) is supplied so the user can adjust the steering effort to within the ECU settings. The maximum torque output of this kit is 40Nm. (The ECU can be upgraded to the Lite ECU at any stage and the maximum torque is increased to 70Nm.)

This kit is designed to help installation, a blank input shaft is supplied to allow the installer to adapt the input shaft into almost any application.

The kit contains – Motor / Gearbox unit, Input Shaft adaptor (Can be machined to fit your steering wheel / hub), Output shaft Coupling (Can be split to allow fitment to your Manual steering unit), Locking pin and safety collar, Signal Generating Unit (This allows the user to adjust the steering effort)

Speed Sensitive Upgrade        Now Available

We now have an Upgraded Loom that can be added to the EPAS Kit-1 or the EPAS Kit-2 to make the units speed sensitive. The “PSGU” simply plugs into the ECU and via a wheel speed sensor this makes the systems speed sensitive. For more information please contact us on (07) 3889 7077.

Longer Input Shaft Upgrade “Now Available”

We now stock a longer input shaft designed to fit our EPAS Kit-1.

This longer shaft has been made to help with installation of our Basic EPAS Kit-1 systems.

The shaft is 400mm long this is 200mm longer than the shaft normally supplied in the EPAS Kit-1 the shaft can be machined to take your steering wheel or quick-release hubs.

This kit is the same as the EPAS Kit – 1 but the input shaft has a collapsible steering column section attached to the top of the motor / gearbox unit. This kit can be installed into road cars, but the installation will have to be approved by your engineer. The installation must be approved under the steering modification / conversion code’s LS1 or LS2 via the relevant transport approved engineer. This system also can be mounted anywhere between the steering wheel and the steering rack or steering box. The maximum torque output of this kit is 40Nm. (The ECU can be upgraded to the Lite ECU at any stage and the maximum torque is increased to 70Nm.)

This kit is designed to allow the installer to adapt the EPAS kit into almost any road car application.

The kit contains – Motor / Gearbox unit, Input Shaft with collapsible steering column section, Output shaft Coupling (Can be split to allow fitment to your Manual steering unit), Signal Generating Unit (This allows the user to adjust the steering effort)

Speed Sensitive Upgrade        Now Available

We now have an Upgraded Loom that can be added to the EPAS Kit-1 or the EPAS Kit-2 to make the units speed sensitive. The “PSGU” simply plugs into the ECU and via a wheel speed sensor this makes the systems speed sensitive. For more information please contact us on (07) 3889 7077.

2 new Electric Power Steering Column systems to expand our current EPAS range.

Pro Street MGU (Motor Gearbox Unit) EPAS100

Pro Street Column (Tilt Adjustable) EPAS102

The Pro Street system’s comes in two styles, Pro Street Column and Pro Street MGU.

Pro Street MGU (EPAS100)
This is a shorter version of the Pro Street Column to help with installation where size may be a factor. This motor/gearbox/unit is also designed to go in line with the existing steering column between the steering wheel and the manual steering Rack or Box, being smaller it can be used in tighter installations, where the size of the unit is a factor. The Pro Street MGU has maximum torque output of 75NM (55lb Ft)

epas100-pro-mgu-photo-with-ups-logo-rear-view.jpg

 

Pro Street Column (EPAS102)
Complete steering column all in one. This unit is designed to be installed in line with the existing steering column between the steering wheel and the manual steering Rack or Box. With tilt adjustable column this unit is easily approved for road use, such as classic cars, hot rods and muscle cars. The Pro Street Column has maximum torque output of 75NM (55lb Ft)

Both Pro Street systems function in the same way but offer a choice of packaging / size options depending on your application.

MODE OF OPERATION for Pro Street Units.
Once the Pro Street units have been installed there are two different ways both systems can be used:

Option 1 (Manual Control)
Manual control of steering assistance by potentiometer “Rotary Knob” adjustment. The weight or “feel” of steering can be adjusted by turning the supplied potentiometer.

For this option you would add the following two items to your Pro Street MGU or Pro Street Column.
The ECU (EPAS108) and the wiring Loom (EPAS112) see photos below.

epas108-pro-street-ecu-ultimate-power-steering.jpgepas112-pro-manual-adjustment-loom-ultimate-power-steering.jpg

 

Option 2 (Speed Sensitive)
This option gives you the best of both, with a Manual and Speed sensitive control at a flick of a switch. This option has the Manual control of steering assistance by potentiometer adjustment (as with Option 1) and also a digital wheel speed input signal, which can be used to increase the level of assistance at parking speeds whilst firming up the steering at higher speed, this is the Speed Sensitive option. A mode selection switch is provided with the harness to choose your preferred method of operation.

For this option you would add the following two items to your column or MGU:

The ECU (EPAS108) and the wiring Loom Speed sensitive (EPAS110) see photos below.
