I have been trying to figure this one out for a long time. I have a Hyster E60XN-33 Electric 4K Forklift that feels like its in a limp mode. I've changed out the encoder bearing, adjusted the foot-petal switch and even swapped out the motor controller but nothing seems to make it go any faster. There are no fault codes showing.

I don't have the AC Controls Program, but I am not sure if that would be any help.

Anyone got any other ideas.
