Bose, any luck on the shifter rod yet? Why do you need a new one?
I have two new developer kits on the shelf, along with one I replaced when it got noisy. Two others are in operation on my trikes. Since I am just keeping the ones on the shelf as replacements when others go bad, I expect I could part with a shifter rod. Send a PM if you still need it.

I hope it's the right tread for this question.
I want to put the actuator in another box then the original plastic cover from Nuvinci. I just don't think it will hold more then one winter in Copenhagen, because of the enormous amounts of salt used on the roads every year (to understand the amount: 2,5kg/m2 of road every winter
).
So I succeeded in finding a perfect aluminium diecast box in black with a neoprene gasket, IP65. To keep it watertight I need to find a solution for the cable/cord from/to the controller. I can't use a normal cable gland because of the plug that goes into the actuator won't go through the gland.
The box is from Camden Boss
192x112x61mm (LxWxH)
Box: RTM5006/16 - BLK
Gasket: FT094-513 5005-15 Gasket
Any suggestions?

Utah Trikes has 8 kits left at $125. I bought one earlier this week.

Thanks for the post. I've been looking for some sort of small transmission to experiment with.
Maybe I can get some use out of the one I just ordered.

Well, quick service from Utah Trikes. Already received my kit.
Was a bit surprised and disappointed that there was no manual or software in the box...
After a good bit of searching, I finally found PDFs of the manuals, but can't find the software / application.
Anyone know of a still good link for it, or can you upload it somewhere or email me a copy? (I'll be glad to host the files on one of my web servers for future need, if I can get ahold of it.)

I'm surprised, since these were supposed to be sealed boxes, that the software wasn't included. I have a couple of spares on the shelf and should open them and make sure they are complete. Mine came directly from Fallbrook.
Anyway, I should have an extra installation CD that I can send you, assuming my extra boxes are complete. Send me a PM if you'd like one of the CDs. Also, if interested, send me your e-mail address and I will send their latest worksheet release since the CDs have a prior release that doesn't handle 12v input to the control system properly. I don't think there were any other changes.

Just in case anybody ever needs it, here is a link to the developers kit software package:

I'm in the process of setting up my first ebike with one of these contraptions. Any suggestions for displays? I eventually plan on linking it to a custom unifying control system and for now I'm going to use the hyper-terminal and an android tablet as a remote desktop to a laptop but it would be nice for something to use in between.

I just got my bbs02 setup working with the developer kit. Just for everyone's info, the control unit does not seem to work much above 50V. I found this out when I was stuck in high gear taking my daughter to school. Going to use a dc-dc step-down converter.

The 48V rated BBS02 should be good for voltages up to ~60V.
Try running the NUvinci on a stand, unloaded and see if the motor cuts out. It could be that you have the Nuvinci in too high of gearing, and the motor is stalling (and cutting out) from lack of torque.

My experiance with BBS02 and the developer kit with a 48V nominal LiFePO4 battery is that it works, but hot off the charger AND fully balanced the voltage is to high for the nuvinci so it won't change gears. What happens is that when I apply throttle the voltage drops and the nuvinci start to work.
In the instruction it states that there is an limit on 51V, but in the controller it is factory programmed to 52V, If you dare you could change this setting in the controller.

Huh. I wonder if this could be what's causing my speed sensor problem (described here). But that sounds different from what you guys are talking about - your symptom is just a failure to shift at all? Have you tried to monitor the COM ports while this is happening? I can communicate with the COM ports (and the display port shows the correct battery voltage), and the drive shifts, but in a crazy way.
I guess it's worth uploading a config file that has a realistic limit voltage, rather than the nominal voltage, and if that doesn't work, I can try running it with my spare motorcycle battery, which is definitely in the right range. Looks like I have my project for this weekend!

Opps Looks like I mis-interpreted the problem. 
I should clarify the the BBS02 Controller can go as high as 60V. The Nuvinci autoshift controller is probably what you meant in regards to the 50V limit.

The nuvinci does'nt have a nominal voltage limit of 48V, the limit is 51V or 52V depending on what config file is loaded into the controller, 52V is for the most recent sold where the manual is'nt updated to this value (the manual sayes 51V).

What do you guys think about using a resister to lower the voltage? Or is it the electronics that cannot handle that voltage?
A resistor wont' lower the voltage, exactly. What it will do is make a voltage divider circuit, where current flowing htru the resistor will drop some voltage across it, but as current flow changes (like during a shift when the motor runs) the current will change and so will the voltage across it (and across the NV).
A string of series diodes would probably do better than the resistor, but not necessary enough.
So you'd probalby need to use an actual regulator setup, either a DC-DC or a linear regulator, to get a steady voltage for the NV that's lower than your pack.

When I installed my NuVinci several years ago I didn't even try to operate it directly from my 48v Ping, but instead used a DC/DC that put out 12V. The software that came with the NuVinci had an error that didn't allow 12V to work properly, but that was corrected in their V1.0.3 editor.
So if you decide to run the NuVinci with 12V be sure you are using the V1.0.3 software.

Thanks. Where can I find the 1.03 software? According to the Excel editor, I have 1.02.

As far as I know all the kits were shipped with the V1.0.2 software. The only thing you need is the EXCEL worksheet. I got the updated worksheet directly from NuVinci when they were still dealing with the kit. I can attach a copy to a regular email, just PM me with your email address.

Got the V103 workbook.
Apparently, the maximum voltage is 53 according to the configuration export page.

Has anyone looked to see if the later Harmony controller would work with the N360 hub? I'm not a fan of how heavy the electric car window actuator is.
