I have the same situation as Eddy and Rens, same controller, software keeps giving a timeout message (and same odd push button).

The controller led blinks red indicating it has power. I have tried switching the rx/tx wires to see if that was the issue, but no luck. This leads me to believe the issue must be with the software. I have tried all different versions of software that is available, but it keeps giving the same message. Versions tried:
LBMC GUI v.4.0.0
LBMC GUI v.3.3.0
LBGUI v.121.18
LBGUI v.120.17

Somewhere in a document I have seen that some controllers require <span>LBMCV2.1.3</span> to program but I cannot find this version available anywhere. Anyone have this version?

Eddy, can you point me to somewhere they sell that specific usb cable I can use to program the controller? The sale page from the controller I have doesn’t seem to have that option, and most of the rest is in Chinese.

This is the controller <span>https://www.ebuy7.com/item/574038970322</span&gt;

It was limited to 25 on each gear so all the 2nd and 3rd gear did was increase the power output until that limit. ie it would only accelerate faster. And I don’t have the programmer cable unfortunately. But if that’s the only workaround I may have to go get it.

Okay, I’ve bought and installed the replacement controller from ebuy and the scooter runs fine, except for one small issue.

The gear switch is not working at all. This is something I was afraid of before I tried it. I have a 2017 model which uses the 3 positional switch and according to people here, with the replacement controller it acts as a push button. By switching to 3 and back to 1 it should still switch gears that way. The difference is that on my scooter even before having the replacement controller my 3rd gear has never been used. It went to 2nd gear fine but 3rd just never worked. It stayed on 2nd as I pushed the button to 3. So with the replacement controller I can’t use anything but 1st gear.

This lead me to believe the controller is installed fine but there’s something in the wiring of the button that makes the 3rd gear not work. With the service manual at hand I tried rewiring the 3rd gear wire to the 2nd gear connection point and vice versa, but nothing changed, it still doesn’t work.

attached is an image of the wiring beneath the buttons on the right hand side of the scooter, as they were originally. also an image of the pin wiring instructions.

I have thoroughly read this topic and I’m considering getting one too. In rural areas you sometimes have to be able to adjust to the higher speeds of other traffic.

I have a 2017 N1S civic just like Eddy in earlier posts. It contains a Bosch motor. Seeing that he’s got the same controller mod from the ebuy website that’s probably my best guess to get.

I wonder about one thing. Do the original controllers that are built into the scooter differ a lot depending on what country you’re in? Or are the controllers always the same? I’m in the Netherlands and I would like to be sure that that controller is fully compatible with my model. I prefer not to run into problems with connectors or wires not fitting.

If someone here is from the Netherlands and has modded it as well, that would even be better to hear from.

Here’s a picture of my current original controller under the saddle. Sidenote: for some reason there were already two connectors loose, one with a black cable and one with a green-yellow cable. Both have a white connector that seem to fit into each other exactly. Not sure what those are. Anyone know?
