MoTeC MDC 9 Setup

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.

Enable ABS Active Detection

If the ABS Active Detection is enabled then the ABS active status from the ABS computer is used as described in

the diff control strategy in the MDC Functionality section.

Throttle Position

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 MDC 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 pressures at which the pump is turned on and off.

The factory default for the low threshold (at which the pump is turned on) is 1270kPa.

The factory default for the high threshold (at which the pump is turned off) is 1887kPa.

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.

Lock Table Axis

The Y-axis of the user mode lock tables is configurable as Throttle Position or ECU Efficiency.

The ECU Efficiency option should only be used when the vehicle is fitted with a correctly configured MoTeC

EVO89 or EVO48 OEM ECU. See Appendix D – ECU Communications for more details.

Slip Control

Enable Slip Control:

If slip control is enabled then the Desired Slip table and the slip control parameters are used to determine

how much extra diff lock is applied to control wheel slip.

If slip control is disabled then the Desired Slip table has no effect.

Max slip control:

This parameter specifies the maximum amount of diff lock (%lock) that can be added to attempt to control

slip.

Slip control range:

This parameter is the amount of measured slip (km/h) above the desired slip at which the Max slip control

lock will be applied. If the amount of measured slip is within the range (desired slip + slip control range),

then the amount of slip diff lock applied is proportional to how far the measured slip is away from the desired

slip.

For more detail on slip control parameters, and slip control examples, see Slip Control in the MDC Functionality

section.
