BionX Codes

[OldRJF]

I'm a newbe here. I looked for info on the codes but the posts all seem to be from 7-8 years ago.

What I am looking for is a discussion that lists codes for:

1. Default Setup
2. Maximum Range
3. Maximum (safe) Power

And these should be for the recent, maybe last years worth, production, CAN bus, updated console and software.

(You can find bits and pieces of code adaptions on the 'net. I used one suggestion, which made the system very responsive but the range suffers.)

The older Bionx systems could be tweaked directly by entering codes directly on the console. The newer ones have less flexibility on that score. Your dealer can tweak many of those settings using dealer-only software and a dedicated hardware interface. Maximum speeds above the limit set by Bionx won't be among them.

That said, it is possible to reverse engineer that stuff and a few folks have. If you're handy you might want to look at http://www.bigxionflasher.org/unlock-bionx.html. If not, there are a few different folks in the US who have what's necessary to do this, and will unlock your system for a suitable fee.

FWIW, Bionx asserts that any tampering with the firmware on your system voids its warranty. (You could probably work around this by undoing any changes as needed, but I thought you ought to know about the issue.)

Since the posting I did the other day I've adjusted parameters on my BionX system (Rev. 64) back to what I think are the defaults.

In particular, code 0007, gain or amplification of the sensor signal, has a lot of affect on range and assist level.

I set the parameter to 3 and you could easily feel the motor kicking in and giving extra help. You could also watch the assist level jumping much higher every time you pushed hard on the pedals.

But this extra help comes with reduced range. Running at assist level 2, with the BionX system in its' default configuration (Code 0007 set to 1), I've been able to get 65 miles on one battery charge on a bike trail with some elevation changes on a trike. This is the Li-Ion battery / 48V / 8.8 Ah / 423 Wh.

Setting Code 0007 to 3 made the trike much peppier. But then I almost ran out of battery at 32 miles.

I prefer to keep the default setting and use the throttle and extra assist only as necessary to not run out of electricity. If I was doing short commutes in a hilly city, I'd use more battery and charge it every night.
