Wiring LCD SW-900 to Lien 12 Fet controller -PLZ help

[Htfan]

Yes, I have the same motor 1500w current, 3000w pick.
I had to try all the wiring combinations until I found the correct pass and hall setting. Lien could not help. But the motor works fine until I ride fast and begin to hit up. The pass wires I beleluve 10- 12 awg- what comes out of the controller.
I suspect that as Lien said the 12 fet, 40A and it can't handle 52V battery and 1500- 3000W. What do you think?
BTW. The support I get from him is very weak and slow.

Like I mentioned before, I'm running 72v 2800 watts on same Lyen controller without a heat or wire melting problem. However, my motor is a 9c and we still don't know what motor you have (or your controller's phase current settings) .

You must have some monster motor drawing too many amps or a settings/configuration problem.

I found a better combination of Hall and Phase and it does not get as hot as before.
But still no communication between the SW 900 and the controller. It does not even turns on and off the controller. So all together it's like an old time bike. Competability is still an crucial issue. I will have to get both LCD and controller which speak to each other.
