You can't really disassemble the Das-Kit Controller. It's fully potted with material.
I ended up carefully picking all of it out to expose the wires to see where they went and to check the printing on the circuit board to find out the firing order of Das-Kit Controller so I could match up the wires to the KT controller to get it working.
Das-Kit likes to do everything upside down and backwards so people like me can't figure how things work.

It turned out that Das-Kit did reverse the firing order, so I had to swap both pairs of blue and yellow wires.
After doing that, my controller didn't work, so I put all the wires back to match up all the colors and that worked.
Seems wrong, but it's working now. Go figure??
So, I ended up really going to town with this install, but you or anyone else with an NCM ebike should have no problem because the motor cable should plug right in for you.
The Das-Kit Controller, by the way, is bullet proof!!
It really is well-built with "Practical German Engineering".
The KT controller is "cheap" in comparison but is also cheaper to purchase at about ⅓ of the price.
So a KT controller probably won't make much difference for you as far as power or top speed goes.
It kinda looks like your motor has a maximum speed/RPM of 45 kph and it has enough torque and power to take you to ~42 kph.
My motor (whatever the hell it is?
) probably has the same maximum speed/RPM but might have enough power to get to 45 kph with the few extra amps that the KT controller can provide.
I'm pretty sure that the Das-Kit CT5-I5 are 22 amp controllers when they are unlocked like yours.
Unfortunately, I won't be able to tell about the lag, or lack there of, with my controller because I didn't connect my PAS sensor (cadence sensor)
The reason I installed the KT controller was because I didn't like how the throttle operated.
I would just touch the throttle and the bike would go to full power until it was going at least 12 kph or whatever PAS mode speed it was at.
It wasn't a real throttle. It's just an on/off switch.
So I decided to install a twist throttle to try and get a more sensitive throttle, but it was exactly the same. Full power or nothing.
So then I bought an off-road display from New Zealand because it would allow me to turn the bike down to Eco mode and gave me adjustments for maximum speed and different throttle settings.
That too was exactly the same.
I turned the PAS off and set my throttle to 6 kph.
I would just touch the throttle, and the bike would launch so fast that it was going 12 kph before it even knew how fast it was going then would slow itself back down to 6 kph.
So I returned my off-road display for a refund (but I still lost over $100 on shipping and duty)
That's when I decided, "enough of this crap!" and ordered a KT controller.
That turned into a real adventure too with the motor cable issue, but everything is close to finished now and I should be ready for a test drive soon.
The KT controller has what they call "imitation torque control" which I think is a dumb way of saying that it is simply "power control" just like a real throttle on a car or motorcycle.
A little bit of throttle gives you a little bit of power, and a lot of throttle gives you a lot of power.
The same "power control" applies to PAS modes as well, with no stupid lag when you stop or start pedaling, and you control how much power the PAS kicks in with. Not just all or nothing with a waiting period.
If I had my way, I'd remove every computer chip on my ebike.
All I want is a battery, a motor, and a throttle.
That doesn't mean that I don't ever want to pedal. It just means that I don't want no stupid robot analyzing me and deciding for me what I want the bike to do.
I want to have that control, not a computer.
Sorry for the rant.
I have a real disdain for artificial intelligence. I think it's naturally stupid.
