I finally found the correct phase/hall sequence on Mxus 3000 + lyen 18fet controller tonight. At first I got 49mph in reverse and it was as quiet as heck. I ran it for about a minute, and the motor, phase wires weren't even hot. Anyhow, I had to swapped a few more phase/hall combo and got about 49mph running forward. I went for a test drive, and the front end just lift off. Top speed were around 42mph and it get there quick. I need to flip the handle bar upside down for a forward leaning position to prevent the front lift off. Or reprogram it to low amperage.
