MoTeC MDC2 10 Setup
Speed Sensor
For Wheel Speed speed measurement method only.
Hall/Magnetic:
If the speed sensor type is hall effect (or equivalent), a hall switching threshold must be specified. If the
speed sensor type is magnetic, the Magnetic Levels table (on the Input Tables tab) must be configured.
Factory default is Hall.
Hall threshold:
The switching threshold for hall effect speed sensor inputs. Factory default is 2.2V.
Input Sources
Throttle Position:
The throttle position can be taken from CAN messages from the ECU (default) or by optionally wiring the
throttle position sensor directly to the MDC2 throttle position input pin. If the optional Input Pin source is
used, the throttle position sensor is calibrated using the table on the Input Tables tab.
Handbrake/Parkbrake:
The handbrake status can be taken from CAN messages from the body computer (default) or by optionally
wiring the handbrake switch directly to the MDC2 handbrake input pin.
Brake Pedal:
The brake pedal status can be taken from CAN messages from the body computer (default) or by optionally
wiring the brake pedal switch directly to the MDC2 brake input pin.
ECU Type
The ECU type option must match the installed ECU (MoTeC M800 or factory ECU).

Magnetic Levels
If magnetic wheel speed sensors are used, the sensor thresholds must be specified in the magnetic levels table.
Thresholds are configured separately for front and rear sensors.
Up to 11 ascending speeds can be specified in the table and linear interpolation is used between points.
Throttle Position
If the throttle position input source is the input pin then the throttle position sensor must be calibrated.
The Throttle Position table allows the throttle position sensor to be calibrated in up to 11 steps, with linear
interpolation between points. The table specifies the throttle position characteristic between the TP Low voltage
(0%in) and the TP High voltage (100%in).
The Read buttons for the throttle sensor high and low voltages can be used to calibrate the sensor if the MDC2 is
powered and connected to the PC. To calibrate, press the TP High Read button with the throttle pedal fully
depressed, then press the TP Low Read button with the throttle pedal fully released.

Hydraulic Pressure
The hydraulic pressure thresholds determine the accumulator pressures at which the pump is turned on and off.
The MDC2 can be configured to use the factory defaults or adjustable thresholds, specified in kPa.
Allow CAN diagnostics
The CAN data stream can be disabled or enabled. This feature may be used to prevent reverse engineering of
user control modes.
