Guys, I'm pretty sure the Bafang Ultra programming is the same as it comes from the factory, no matter what bike it's installed in. As a (very curious) new owner myself, I'm finding that good/very relevant info is being spread from one end of EBR to the other in each of the brand forums that are using the Ultra motor (eg. Biktrix, Luna, Fey, M2S, Rize, and many others). My idea here is to try to provide a central location for some of the great ideas I've read about.
After riding your new bike for a bit, I think many will agree that the software can be improved on - considerably. You'll likely find the degree of controller adjustability one of the neatest features that come standard with every one of these motors. It needn't be difficult either.
My initial thoughts revolved around a throttle that I thought could be tamed down, and the torque assist was too much at low speeds, allowing just ghost pedaling at speeds under about 10mph, even in PAS 1. Both turned out to be easy fixes - and increased battery mileage noticeably....
Here's the cable I used. Note it's 18" length. I bought a 6' USB extension at Walmart (sorry no link there) so I can just pull the bike up to the work bench and plug it in easily.

Software, oh boy. I did do a bunch of reading on the topic to try and get my head wrapped around the topic. What I learned is that the BBSxx software is 100% compatible with the Ultra, but that BBSxx software does not have the 4th "torque" tab. You'll see what I'm talking about when you start messing with it. Here's the file you need for the Ultra- which includes the 4th tab!

You'll find Roshan from Biktrix and Karl from Luna have spent a lot of time messing with these big Bafangs. They know what they are talking about - and they have some details regarding each of the variable parameters there are. What they do, and where they set them. I would pay way more attention to what they have to say about the parameters than how they set them. You'll find personal priorities are all over the ball park here, with way different settings prefered by road bike guys, aggressive mountain bikers, and even hybrid riders riding a road/trail setup (like I ride).
That said, here's some reading material regarding tuning your Ultra -

Do some google searching. There's a TON of info available on this topic! You Tube is over flowing! Just remember that these guys may have tuning priorities that are going to be WAY different from yours. Resist the temptation of installing ALL of their ideas on YOUR bike! -Al
