Blunami Diesel EMD 8-Function Sound Decoder Plug & Play (TUC885613)

The Blunami 8-Function Diesel Sound Decoder is a plug‑and‑play replacement that brings authentic diesel sound and control to a broad range of locomotives. As a universal factory-board replacement, it works across many manufacturers’ diesel models and covers scales from HO to S. It supports DC, DCC, and wireless operation, and can be controlled easily with the Blunami App for setup and operation.

Equipped with eight-function outputs, it offers flexible control for sound and lighting effects. A highlight is Dynamic Digital Exhaust, which automatically adjusts exhaust notes to match the motor load—so the sound changes as the locomotive climbs grades or when throttle is increased, delivering a more realistic experience. Calibration and control are accessible via the Blunami App, simplifying setup across DC, DCC, or wireless operation.
