You can get the Ohlins Race SCU for it, or replace it with the manual damper. In order to replace it, you must remove the stepper motor to keep the light off and store in somewhere tucked into the bike. There have been a few threads on this.
While you may be able to swap internals, this would be extremely dangerous. The algorithms in the SCU are based on a known damping rate. If you change the damping rate, the computer can lock up the damper inadvertently. The SCU only gets feedback from the control motor, not from the actual damper position. So if the damper tries to tighten the damper and thinks it can go to setting 10, but you've modified the internals, setting 10 may be WAYYYY too much now and there's no way for the computer to know that. Don't fuck with the internals.
