I stayed up half the night messing with track and connections to cure it but had no luck. I programmed engine with the SD40 module it came with. Tried resetting engine, reloaded module nothing worked.
Between speed steps 20-45 it jerks back and forth and sometimes doesn't respond to throttle or slows down. Once I go over about speed step 50 it ramps up to speed and runs fine. This is all with Odyssey switched on. When I turn Odyssey off the unstable speed problem goes away, but loco doesn't start rolling until I hit about speed step 20. Any ideas?
This is the new BN SD40.
I also ran my lionchiefs around the same 060 loop track with no problems. So Im pretty sure its the legacy signal or in the engine itself.
