A snowmobile includes a frame and a plurality of skis operably coupled to the frame. To compensate for the frequency drifts of the transmitters, the embodiments of this invention, with minimum pre-processing of the received data, allow for on-the-fly adjustability of the receiver bandwidth by merely changing a pre-calculated weighting function. In systems such as SCR systems, where the liquid reducing agent may freeze when not in use, directing already thawed liquid toward other system components can help thaw the frozen reducing agent at desired locations first. When each master device performs read access to an address of a storage device, data read out of the storage device is compared with data corresponding to the address in the scoreboard.
