Settings for KT Controller and Swytch Hub

[TBoy1]

I just recently changed my Swytch kit controller to KT 22A Controller Kit that I ordered off Amazon, and since it was difficult to find information on the correct settings for the new controller, I thought I would share them here. I bought a complete KT kit and replaced all the Swytch components other than the hub, it's really the only way to make everything work properly. This is the battery replacement that I used as well https://www.amazon.com/gp/product/B089NRZMWK/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

It doesn't matter which KT Display you use, the options would be the same.

Important info for Swytch hub:

• There is a 250-watt and 500-watt hub, but I believe the settings for both are the same.
• The hub uses 6:1 ratio with 16 magnets in it. (To determine P1)
• It has 1 magnet for the pulse signal (For P2)
• The rest of the settings are attached, but are my setting preferences, where applicable.

So P1 is 96.

Correct (6:1 Ratio) 6 x 16 Magnets in the internal Hub (Per picture) = 96

I tried these settings and it works except the speed display is off (It reads 2mph when I am going 12mph)
also there is a delay in the pedal assist kicking in until I reach a certain speed.
I would appreciate any suggestions

Thanks

22A is too much for a Swytch motor. You need to cut down the max current in the settings, especially with a sensorless motor, like the one shown above. I'm not sure, but I think they changed to sensorless motors after the MK1 kit. In that case you don't need to worry about P1.

Which version motor do you have?

The speed display comes from the speed sensor and wheel size unless you don't have a speed sensor, then it comes from the P1 setting, which you know because no speed is indicated when freewheeling.

Thanks for the quick response.
Here are pictures showing the motor number and also the controller

Doesn't help. Is the motor sensored or sensorless?
What speed sensor do you have - on the wheel, in the motor or none?

Normally when you get 2 mph instead of 12 mph, it's because you have P2 set to 6 instead of 1. P2 is the number of magnets that make the speed sensor pulse, so if you make that mistake, the speed displayed would be 1/6th of the actual speed.

When purchasing the battery from the Amazon link make sure it is 36V 10Ah-100W-500W

… in the hope of clarifying, all Swytch hubs (both gen 2 and 3) have the commonly-used nine-pin connector, and that would make the hubs sensored I believe.

One would say yes , there is little logic in not having a fully sensored hub.

I had it a\t the back of my mind that te first ones were sensorless.

My mk1 Swytch died. Tried fixing controller - waste of time. New controller £120 from China. No thanks. Got KT LCD 5 display, KT controller and extension lead for motor. My settings
