I have Athearn SD70ace's and Intermountain ES44AC's, both non-sound, that don't play well together. The IM units require higher starting power than the Athearn.
Has anyone discovered a CV fix for the Loksound decoder?

That's just common speed matching. CV2 adjusts the starting voltage. You might also want to adjust the acceleration as well, which would be CV3. If the LokPilot decoder accerates slower than the Soundtraxx, lower the value in CV3. Conversely, if you like the acceleration rate of the LokPilot, increase the value of CV3 in the Soundtraxx.

Hey Mark,
The new AC Gevos will stall under load, pulling a train up a grade at our club. They don't slip, the motor just slows down and they stall. Almost like it was programmed into the decoder. A pair of older Gevos with Soundtraxx will pull 70 cars, the Loksound pair will stall with 50. Any thoughts?

Looking through the settings in that decoder file, I noticed the regulation frequency for the BEMF is set to 100%. That's fine for a switcher, but for a road unit, the regulation frequency should be considerably lower allow the engine to have full unharnessed power at higher speeds. This is set using CV56. From the factory, it is set to a value of 255. Try setting it about half that, around 125 and see what you get.
Mark.
