I am running a MTH N&W Class A PS1 locomotive that I converted to TMCC some years ago with a TAS 8&15 amp DC SAW Command and Railsounds 4.0 Conversion Board. I use MTH DCS version 3.0 to control all my engines. Top speed of the Class A is reached when 32 speed steps are displayed on my DCS Remote. I need more speed... after all, this is a fast freight! Recently I discovered (on an internet search that took my to the DCS Command User's Guide) that DCS Version 4.0 has an AX1 softkey that allows the TAS steep steps to be changed from 32 to 128. I can't seem to find this feature in DCS Version 3.0.
Can anyone tell me how to increase the TAS speed steps in DCS Version 3.0?
