MoTeC SDC3 - Manual (Page 13)

MoTeC SDC3 11 Setup
The width of the diff control pulses varies linearly with the desired diff lock, from Min Pulse Width at 0% lock
to Max Pulse Width at 100% lock. The factory default is 80µS to 800µS.
These parameters should only be changed by advanced users.
Output Current Protection:
The diff current output is hardware limited to a maximum of Output Current Protection Amps, regardless of
the control method used. If the Current Control method is used, this current must be at least one Amp
higher than the Full Lock Current. The factory default is 11.0A.
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 MAP Sensor.
The MAP Sensor option should only be used when the vehicle is fitted with a correctly configured MoTeC WRX
V910 OEM ECU. See Appendix E – 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 SDC3 Functionality
section.
Diff Temperature Override
Override mode:
If this functionality is enabled, the current user control mode (1-4) is overridden with the configured override
mode (Open, Locked or one of the 4 user modes) while the rear diff temperature input is active. For more
detail on the temperature override functionality, see Diff Temperature Override in the SDC3 Functionality
section.
Speed Axis
Up to 11 values can be specified for the speed axis that is used in all of the user mode Braking and Acceleration
tables. The axis values must be ascending and duplicate values are not allowed. Spacing between values is not
fixed, allowing non linear axes.
Throttle Axis or MAP Axis
Up to 11 values can be specified for the throttle or MAP axis that is used in all of the user mode tables. The table
type (throttle or MAP) is determined by the Lock Table Axis option. The axis values must be ascending and
duplicate values are not allowed. Spacing between values is not fixed, allowing non linear axes.
