BLI SW7 Lurches Through Low Speed Steps
Hello, everyone!
I have a new BLI SW7 with a Paragon 2 decoder. I've noticed that the engine has poor low speed performance. I've tried tweaking the CVs using Decoder Pro. Now it starts fine at speed step 1 but literally jumps to each additional speed step until it reaches about step 5. This lurching doesn't go away when playing with momentum or BLI's speed smoothing.
I've poured over the BLI manual and searched on-line forums. I suspect the answer is hidden within the indecipherable K-P-I-D settings (or whatever it is) or there about. What are your thoughts?

I have a BLI SW decorated for
I have a BLI SW decorated for the Illinois Central which is the first railroad I worked for as a brakeman. Right out of the box the engine ran/runs smooth and slow...so slow I called BLI a few years ago and asked how to increase the speed as the prototype locomotive I rode, was able to run faster when in main line service. The response I got was less than helpful as the BLI guy said they were built that way to replicate a slow, speed, switch engine. Truthfully, I believe the respondent's answer was a bit "lame" and he was shooting from the hip not really knowing how to change the speed.
However, I am more than happy with this little, engine's performance, albeit slow... as it fits the occasional use as a museum/short line locomotive.
BTW, I too have had challenges with programing this unit.
