Blunami Diesel User’s Guide 5
Using Blunami
The Blunami Digital Sound Decoder is designed to enhance your model railroading experience
by giving you a wide variety of innovative features and incredibly realistic sound for your
models. Some of the features discussed in this user’s guide include Dynamic Digital Exhaust for
diesel locomotives, Hyperdrive2 advanced motor control, Flex-Map function mapping
technology, prototypical dynamic braking, two volume mixers, HEP mode, independent and train
brake functions and Fireman Ed sound effects. Blunami also provides selectable airhorns, bells,
prime movers, air compressors and couplers to allow more versatility in creating your ideal
model railroading experience.
You can start using Blunami right out of the package without making any changes. However,
you may adjust settings at any time by making changes to Configuration Variables (CVs). Most
DCC decoder and command station manuals call this “programming”, though this is misleading
and sounds scarier than it is. At no point are you required to learn software programming! This
guide will walk you through operating and adjusting Blunami to its full capacity.
*Auxiliary HEP generator and straight-to-idle are not included in software releases prior to version 1.2
