Anyone have any advice on resetting the defaults or smoothing out the motor settings? After trying to utilize autotune CV54 numerous times and adjusting a few other values on my lokprogrammer I now have two GP diesels out of commission. I'm not sure what else I can do in order to fix them. They are stuttering and making odd sounds. One is a loksound select micro and the other is a loksound 5. I should have never tweaked with any other adjustments.... I was originally trying to increase the voltage reference after the autotune cv54 because they were running much too slow and the engine was notching too many times before getting to a decent speed.
