Ok, here is 565 running light. Legacy speed step 1. Not perfect but not too bad. Important for me is I can double or triple head it with any other Legacy engine with an RCMC including my other Mogul and 10 wheelers. Something I can't do with the TMCC Moguls. They only run with themselves.
I believe Dave Olsen indicated one issue with these is the driver size and gear ratio put them at the far edge of what Legacy speed matching was capable of. I can deal with the mechanical issues but can't do anything with software at this point. Maybe some time in the future we will be able to play with files like you can with DCS engines.
