So I have an existing voilamart motor 1000W motor and bought that KT controller 48v controller with a KT LCD3. The throttle is working but not much else. Has anyone done this and able to configure the controller to work with this motor? No luck with PAS and not registering any speed. It does register watts used when I use the throttle though.

Any help getting this working would be appreciated!

So according to this thread, the PAS sensor was the result of changing the wires, i.e,
https://www.pedelecs.co.uk/forum/threads/power-issues-with-voilamart-kit.40299/

"On the PAS there are red, white and black and from the controller, yellow, black and brown. They are connected as follows;
black to yellow
white to black
red to brown"

"That's why it doesn't work. it should be black to black, red to brown and yellow to white.
The white wire is for a speed sensor integrated into the motor. if you don't have the speed sensor in your motor, you need to connect an external one if you want to see your speed on the LCD and ypur system not to go to sleep every 5 minutes or whatever it's set to."

So I connected black to black, red to brown, white to yellow. PAS now works! Although still not seeing speed...
Any idea what might be up with why I'm not seeing speed?

White line. Sometimes its marked "cs" on the board
 
There is a six pin connector that go from the motor to the controller but # of wires and colors all match up:
Red->red
Blue->Blue
Black-Black
Green->Green
Yellow->Yellow

Which wire controls speed or could this just be a setting in the KT controller I have to change?

Here are my current settings:
P1 - 46
P2 - 1
P3 - 1
P4 - 0
P5 - 15

C1 - 0
C2 - 0
C3 - 8
C4 - 0
C5 - 10
C6 - 3
C7 - 0
C8 - 0
C9 - 0
C10 - N
C11 - 0
C12 -4
C13 - 0
C14 - 2

I've got a 1000W voilamart motor that I was hoping to use a KT 48V controller with my kt lcd3 display with.

* Throttle works
* PAS seems to work (I had to switch around the wires a bit, see https://www.pedelecs.co.uk/forum/threads/power-issues-with-voilamart-kit.40299/)

But I get no speed displayed.

The existing controller that came with the voilamart did register speed.
Anyone hooked the two of these together and got things working?

Here are my current settings:
P1 - 46
P2 - 1
P3 - 1
P4 - 0
P5 - 15

C1 - 0
C2 - 0
C3 - 8
C4 - 0
C5 - 10
C6 - 3
C7 - 0
C8 - 0
C9 - 0
C10 - N
C11 - 0
C12 -4
C13 - 0
C14 - 2
 
So it appears P2 needs to be set to 0 not 1.

It is registering speed now!

It is registering speed now! Tomorrow is take it out for as spin, see if any other adjustments are needed.
 
Just a follow up with this. I really like the KT controller + lcd over the one that came with the voilamart motor (sw900). The pedal assist is way more responsive, and the various pedal assist levels actually work, Level one maxes out around 150 Watts, configurable to be less.
 
Im not an expert but if a kt controller doesn't allow for full functionality with anything but a kt display, and the voilamart kits use different displays ie sw900 ( they read with different protocols) My guess would be that's your issue.

OP stated he's using a (KT) LCD3 display....
 
Yes but the voilamart kits don't use a kt controller so won't work with a kt300 display

So if a kt controller doesn't work with a sw900 display I'm guessing that it's the same in reverse, a non kt controller like what comes with the voilamart kits won't work with a kt display
