Programmable Signal Generation Unit (PSGU)

Now available is a Programmable Signal Generation Unit (PSGU). This unit allows you to connect with either the Compact, Corsa B or Corsa C or EPAS Lite ECUs. From there you can interface with a wheelspeed sensor (supplied) allowing you full speed sensitive steering.

Fitment and calibration is simple with the unit designed to work with anything from 1 to 36 targets per wheel revolution. Simply drive down the road and when the weight of steering is comfortable, press the calibration switch. Subsequently everytime you slow down below this speed the steering will get lighter. A flash memory in the unit ensures the data is retained once the power is removed and a re-calibration can be carried out at anytime should you wish to adjust the speed at which the steering becomes lighter.

Pulse Width Modulation Unit (PWM)

This unit is designed for circuit racing only. A PWM input from your data system is converted to a signal for the EPAS Lite ECU to process. This allows the user to set up a different PWM value for each part of the circuit allowing the weight of steering to be pre-selected for each corner without the need for a wheelspeed sensor. Ideal if you only want the steering lighter for one tricky corner or if your championship does not allow the use of a speed sensor.

EPAS Lite ECU (Motorsport EPAS System Only)

This entry level ECU is designed to handle transient currents of up 60 amps. Connection is via an 18 way PCB header. This system:

• Has dedicated fault lamp output.
• Power level adjustable by rotary switch.
• Optional software disk available to tune ECU to vehicle and monitor real time ECU operation.

EPAS Ultra Power Steering ECU (Motorsport EPAS System Only)

This Ultra ECU has been designed to handle transient currents of up to 100 amps. Connection is via 2 Autosport connectors. The ECU has the same functionality of the EPAS Lite ECU, but with the following additional features:

• CAN 2.06 interface.
• 4 x Digital outputs.
• 2 x Speed inputs.
• 2 x Digital inputs.
• 3 x Analogue inputs.
• Internal heatsink temperature monitoring.
• Ability to create your own steering map when optional software is used.
• Internal temperature and peak current tell tales.

The CAN Bus can be used to control the power levels or input ground speed to make the unit speed sensitive. Information on the systems settings and performance is also available on the CAN Bus Interface.

Also available for all systems are a range of universal joints, steering wheel bosses and interconnection shafts
