I just recently installed a ERR Cruise Commander in a 2005 (?) Atlas Dash 8 and have questions on programming. To change the motor size the commands are aux1 + 0 + aux1 + 0 + Brake or Boost. How do you do this on a Legacy controller? What is the exact sequence of actions? Does the controller need to be in CAB-1 mode? Do you press and release aux1 then 0 then aux1 the 0 then Boost, the engine jumps forward as if just the boost is pressed?
Thanks, Frank

Yes, you press AUX1 and then the zero. You can press the key in the zero position in TMCC mode or just switch to CAB1 mode if you want to see the numbers. Yes, the engine will move when boost is pressed, but you only press it momentarily. Obviously, you have to allow for the movement.
I have never changed the motor size from the default large motor in hundreds of installations. In the past I tried the small motor setting, and I could not detect any running difference.

Thank you John. I was not sure on the sequence of presses as I was not able to detect that a change had taken place.
So the same applies the setting the speed steps. Per the instructions, the default is 100 speed steps. On the Legacy controller in TMCC mode, as the throttle is increased, the throttle value appears (1, 2, 3, ...). Is the value displayed speed steps? At approxmately half throttle, the value displayed is approximately 14 of 15. Does this correlate or signify 32 speed steps? The throttle response seems to be a little "notchy" as I would expect with 32 speed steps. Any insight to this is appreciated.
Thanks, Frank
I don't know that there is an indication. I tried three different Cruise Commander equipped locomotives, only one beeped after the speed step setting.
Thanks for your input John. Much appreciated.
To address my suspicion that I am experiencing 32 speed steps, a fellow club member informed me that to realize 100 speed steps I'd need to run the engine under R100 mode on the Legacy controller. Apparently TMCC only supports 32 speed steps. I did find another thread here a little while ago that confirms. Learning. Good stuff...
Correct, that's why R100 is there. FWIW, you will also get 100 speed steps in CAB1 mode, just no throttle graph or keypad icons.
