Subaru Diff Controller 3 (SDC3)

The MoTeC Subaru Diff Controller 3 (SDC3) provides electronic management of Subaru's active centre differential systems, giving tuners precise control over torque distribution characteristics. This third-generation controller integrates seamlessly with MoTeC ECU systems to optimise differential behaviour based on driving conditions, throttle position, speed and other critical parameters. Ideal for performance Subaru builds requiring advanced differential management beyond factory capability. The SDC3 enables workshops to fine-tune differential response for circuit, street or rally applications, delivering improved traction management and more predictable handling characteristics through your existing MoTeC tuning software.
