Basic Programminglarger values for these CVs; we therefore suggest setting CV 3 and CV 4 to aminimum value of 16 or higher.If you are using 14 or 28 Speed Step modes, setting CV 3 and CV 4 to anyvalue greater than 0 will also improve the Tsunami’s throttle response. Whileit is accelerating or braking, Tsunami interpolates between speed steps soin effect, your locomotive will respond as if it were being controlled with 128speed steps. No more sudden lurching from one speed step to another!Select the Speed TableTsunami provides 14 preset and one loadable speed table that can be usedfor several purposes:1. Matching the Auto Exhaust chuffing rate to locomotive speed.2. Speed matching one locomotive to another.3. Changing the feel of the throttle. For example, you could configurea switching locomotive so there are more speed steps available atlower speeds for switching and fewer steps at high speeds where thelocomotive is seldom operated.4. Compensating for an improperly designed driveline so the locomotive willoperate within its prototypical speed range.Preset Speed TablesCV 25, Speed Table Select, is used to select which speed curve will be usedby the DSD. CV 25 may be programmed with any value between 2 and 15 toselect one of the preset speed curves shown in Table B, below.Table B.
