Q: Are there different versions of ‘firmwares’ available for my NIU and what are the differences/advantages/disadvantages?
A: Yes, definitely, there are several known software revisions around – all undocumented.
Here’s what we know so far (gathered by users all over the world), columns filled with data where available…
- You’ll get the software revision from the App, it seems it always claims to be “latest version”
- The “ECUKRS” version name hints towards the official Austrian importer KSR, maybe tweaked by them
- Official dealers have a tool to update your firmware. If you have severe issues, it’s worth a try. That said, you might loose other nice features as it seems the newer releases are ‘tamed’ a bit.
| Model | Updated through | Version | V-Max | emergency operation at | comments |
| N1s 2017 | controller update & OTA | ECUKSR1.3 (Nov 17) | 47km/h | 15% | + smoother starting
– less lively |
| N1s 2017 | dealer | TRA01V08 | |||
| N1s 2017 | TRA01V04 | ~53km/h | 20% | ||
| N1s 2017 | TRA01V06 | ~53km/h | 20% | – sporadic amperage display failure | |
| N1s 2017 | TRA01V14 | ~53km/h | |||
| N1s 2017 | TRA01C02 | ~49km/h |
If you have a revision to be added, come and join the forum – there’s a special thread for this 😉
Additional comment concerning changes between TRA01C03 and TRA01C10 : The scooter does automatic recubation when the speed exceeds 50km/h downhill (it slows down). I did not see this behavoiur with the TRA01C03.
There is a mistake in my first comment: emergency Operation limit for TRA01C03 is 10%. The 77% is the battery level i needed to do the upgrade to the TRA01C10 FW version….
I got my N1S 2018 shipped with TRA01C03:
Vmax = 51km/h (downhill more)
Emergency Operation at 77%, maybe 70% (67% was not enough and the upgrade did not start!)
I did the updgrade to TRA01C10 today:
Vmax = 50km/h
Emergency operation not yet tested.
Clock works now. contact to app seems more stable. It is now possible to disable GPS.
Well… please… is there any place where I can download that software…?
I am very interested on that…
Yes… I know… only official dealers can do that…
But… I repeat again :)… is there -do you know- any place where I can download the software?…
thanks

Sorry, not that I know of.
