Tsunami2 (V1.2) True Idle lets you run your Model Trains YOUR WAY!

With all of the hype around the new Proto Throttle we have had a lot of questions about our True Idle feature. In this video, our product expert explains the feature, shows examples of how it works, and explains how real locomotives operate in these scenarios.

To accurately simulate how a real locomotive works, original Tsunami2 decoders did not change the prime mover when going from speed step 0 to speed step 1. We found that it is a common customer perception that the prime mover should notch up when this happens. So in Tsunami2 software version 1.2 we added this in for you!

CVs used in this video:
CV 112: Enable the E-Stop Idle, Alarm Bell, HEP Generator and True-Idle Modes

Add a value of 8 to CV 112 to regulate the prime mover notch RPM levels to create an idle notch. Most diesel-electric locomotives use the same RPM level for this idle notch and the first traction notch, or notch 1. Moving the throttle lever on a diesel locomotive from idle to notch 1 simply engages the generator, allowing it to provide electricity used to move the locomotive down the track. It does not increase the diesel engine RPM level.

Enabling true-idle will change the way the decoder regulates the prime mover sound effect in response to increases from speed step 0 to speed step 1. When enabled, the prime mover will not increase in RPM level until the model has reached the point set by the auto-notching bits in CV 114.
