gunrunnerjohn posted:TMCC stuff has always been somewhat of a crap shoot in an MU. Many times, they work better with cruise control off. The only TMCC ones I've had pretty good luck with are the ERR Cruise equipped ones, it has a "nudge" feature to adjust the speed curves.
I have 3 of the Atlas Dash 8-40CW that the manual says have the nudge feature. I am using a Cab2 and can't seem to make that feature work. Manual says Aux2 four times with a 1 sec spacing followed by Boost or Brake to match the speeds, then sound the horn. Part of the problem may be that when using TMCC, the engines won't hold their boosted speed when Boost is released like a Legacy engine will. When I try the procedure nothing happens to the speed curve when the engines are in TMCC mode. If the engines are switched over to R100 without making any other changes, the engine that was boosted runs like it was in a very much higher speed step in the first few speed steps and then it drops back to running slower at higher steps as if nothing had changed. Any suggestions?
