This system is designed for those requiring a backup steering system or for applications needing high levels of steering assist such as off road vehicles. The user can fine tune the 5 adjustable steering maps (via a rotary position switch) to ensure the best feel and compatibility with the chassis. CAN bus connectivity ensures that all operating parameters can be exported to the vehicle’s data logger.
The system comprises the following parts:
| Operating Voltage | Nominal 13.8V DC |
| Maximum current draw | 160 Amps |
| Average current draw | Circuit dependent |
| System Weight (MGU & ECUs) | 9.75kg / 21.5lb |
| Maximum Torque Output | 220Nm / 162lb ft |
| No Load Rotation Speed | 780 degrees per second |
| Input / Output Spline Pattern | 19mmDD |

EPAS35 Midi ECU
As an alternative to the motorsport system we also offer the EPAS Midi System comprising the following parts:
The Midi ECU uses a cost effective folded metal enclosure with a plastic interface connector. The system is ideal for applications where overheating of the ECU is unlikely to be an issue, such as lighter vehicles used for track days.

The Pro Race steering system is designed to be an entry level electric power assisted steering system for competition/off highway use.
The system comprises the following parts:
The MGU option is installed inline between the steering wheel and the steering rack (the internal torque sensor detects the amount of driver steering input and then engages the electric motor to assist). The Pro Column is a complete height adjustable steering column.
The Pro Race Wiring harness comes complete with a 6 position rotary control (off and 5 levels of assistance) fixed by factory set maps.

There are two options for controlling the EPAS motor:
Manual control of steering assistance by potentiometer adjustment.
For this option you would add the following two items to your column or MGU:
A mode selection switch is provided with the harness to choose your preferred method of operation, which can be either: Manual control of steering assistance by potentiometer adjustment (as with Option 1) or 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.
For this option you would add the following two items to your column or MGU:
