Surprised someone like FanRailer hasn't jumped on this one given his proclivity to diesel-electric mods and it's been since November.
To be honest, I've tinkered around with this particular loco after viewing FanRailer's modding tutorial on YouTube sometime last semester. Even though I'm primarily concerned with steam loco physics, would you like to give my Dash 9 tinkering a try?
Changes would include:
-coupler fix
-dynamic brake fix (according to figures by Al Krug)
-t.e. fix (again, from Al Krug)
-adjustments to horsepower
-better t.e. to speed curve
-better dynamic brake to speed curve
-honest-to-goodness 8 throttle positions like it's SUPPOSED to have - the RSC/DTG model for whatever reason has 9
-along with fixed amount of throttle positions comes an edited t.e. to throttle curve. FanRailer in his video argued that this file is not so important and so would only have values for 0% throttle and run 8. Al Krug included an approximate power setting for each throttle position, however, that makes the real engine somewhat of a unique challenge to operate through reduced speed zones and yards (the difference in power between Run 1 and Run 2, for example, is 150% while the difference between Run 2 and Run 3 is 100%). I have attempted to recreate this in the t.e. to throttle file and it seems at least IMO to match the description.
-adjustment to idle and max rpm
The changes so far only apply to the default BNSF Dash 9. I also started experimenting with the NS Dash 9-40CW which would include an improved numbering scheme right off the roster.
If what you've done is stupid but it works, then it really isn't that stupid at all.
