Hey Axel, just a quick question, since I have looked at the forum rules but it seems to be empty.
I am selling my replacement ECU controller of my NIU N1S 2018.
Can I offer it to the Forum members?
Thanks!
Enrico
[quote quote=1853]Hi Enrico, I have installed the 72182 on my 2018 after March, and everything works as you describe. However, I notice that the ampere never reaches 100% even though I give full throttle. It stays on 80%. Is your ampere meter showing 100% on full throttle? If so, any thoughts on what might be wrong on my end? Speeds are according to your specs but the oumpf is a little weaker than before. thanks, S[/quote]
Hey Sancho,
yes that is completely normal, the ampere reaches 100% only in few occasions and most of the time is between 0% and 80% depending on the current needed from the motor. I still reach 65+ kmh without being at 100% ampere.
cheers.
Thanks for the clear explanation.
Hopefully someone will also be so kind in the future to upload a photo of the actual controller-PC setup. I would do it (and eventually will) but I don’t have access to my scooter until end of October.
[quote quote=1415]Do like it says in the picture: unplug everything, plug the cable end with the black UART connector into your controller and push the pins of your USB adapter into the black connector with colors matching. Power for programming will come from your USB. Cannot break anything, only 3.3 Volts.[/quote]
Mate, sorry but this is not clear for me (I am no electric expert), nor is the explanation on the picture they sent you from China.
What is a UART connector?
Where on the controller are you supposed to plug it?
“Unplug everything” means take it out from the scooter and just use the black connector and the controller? What about the smaller box?
If you could be more clear, we would really appreciate it and the whole forum can learn from your experience. Thanks!
I see, but unfortunately my controller is different and I have no idea where to connect the usb cable. As you can see from the pictures I posted earlier, the cable open, stripped out, you have to connect cables manually on one side and the usb on the other side. Anyways, I am actually happy on how the scooter goes right now. Not crazy fast, but definitely worth the upgrade.
Hey Eddy, congrats on the succeful installation of the new controller. You say you will program it to modify the speeds in each gear. Any info on how to do that? Are you using a special software? How do you connect/communicate with the controller?
Thanks!
Hi, I don’t have a Youtube Channel, so here you can download the videos:

Maybe some of you can upload them and share the permanent link?
To answer Ben’s question: you just need to buy the controller kit for your scooter model and everything will be included in the box. I also bought the data cable but I had no use for it. There are no instructions so I don’t know how and when to use it. Maybe the video explains it, but it is in Chinese.
As for driving experience:
– Mode 1: 35kmh approx.
– Mode 2: 58kmh approx.
– Mode 3: I haven’t had enough time or space to test. After 60kmh the speed increase is veeery slow, you need a large distance. Then again, I’m almost 100kg, that counts.
Battery wise, I suspect you lose a bit, but not too much. I always calculated 6km each 10%, right now it could around 5.5km. But I need more time to test.
App is working normally.
Cheers

So, here are some photos of what I received from China (split in two posts). PS: at first I thought I bought cakes instead of a controller. :-)))
Really love the packaging… timeless! [/quote]
I know man, a bit scary at first, but I must say the seller was helpful and even sent me some installation videos. 🙂
By the way, any way I can share the videos on the forum?
So, I have installed the new controller to do some testing and IT WORKS indeed!
Here are some photos of the process. First, you see the original controller and how it is installed in a 2018 model. Comparing the two controllers, you can see that the new one is bigger, which is a bit of a problem, as you will not be able to tie again with four screws. You can only put one screw in, then I used some tape to hold it in place. It seems pretty stable, I will check in a few weeks. You also have to fix the little box, but there’s space on the right side, so I taped it there.
Once you power the scooter again, evrythinglooks exactly the same. A first speed test on the stand gives me 29kmh on mode 1, 58kmh on mode 2 and 97kmh (!!) on mode 3.
I couldn’t test it on the road, but I think your weight will affect mode 3.
I would have to test also the battery life in mode 2 and 3 and see how much we lose in range.
Of course, please remember that this only for testing and it is illegal to circulate with it!
Here are some photos.
Yes, that is what they state. Although I have not yet opened my N1 to verify that everything is correct.
