Luna BBSHD Ludicrous V2 controller documentation

[BUD WHITE]

I have finally dialed this wonderful V2 controller to my liking and just came here to say that this is by far the most fun I have had on any of my PEV's, including my upgraded ASI BAC 4000 Sur Ron X. This enabled my fat bike build to be 3 different ebikes by a simple few pushes of some buttons to change one of my custom profiles. I have 2 questions for the future. 1. Is there any plans to create a torque sensing pedal assist option to a BBSHD in the future? And... 2. Is there a way to make my Ludicrous V1 controller bluetooth enabled at some point? Thanks again for inventing this controller. Cheers.

I'm happy to hear the experience is on par with a modded Sur-Ron! Can't overstate how big of a deal that is.

I have 2 questions for the future. 1. Is there any plans to create a torque sensing pedal assist option to a BBSHD in the future?

I think its not viable to retrofit a torque sensor into a BBSHD. Firmware can read torque sensors but mechanically its just too involved. There is an M600 ludi on the works with the same software platform you know and love, which does have torque assist, but the motor is much smaller so its not in the same league as a BBSHD.

And... 2. Is there a way to make my Ludicrous V1 controller bluetooth enabled at some point? Thanks again for inventing this controller. Cheers.

Nope. V1 is a modded bafang controller which means we can't introduce any firmware or hardware improvements like that, only bafang can do that, and they don't. An uart to bluetooth adapter could be installed, but the bafang protocol is so poor that there isn't much to gain there and can't be made compatible with the vesc app. VESC datalogging is super rich, to the point I can log 25,000 samples per second to analyze faults, or log a full week of dyno operation.

Thank you again for answering all of my questions Marcos. I am off for a long ride on the beach. Have a great day. Cheers.

Is there any conflict with the Ludi V2 and installing the new firmware from EggRider (V2.5)

[marcos]

No problem, been using that new screen firmware for a while and its also required for 72V setups as the new eggrider firmware can print correct voltage information

Good news, your drive unit is getting even better!



Here at Luna we keep working on the Ludi V2 day and night, and after coding, testing and gathering user feedback we have some improvements to share in this new firmware release. It also comes with small tweaks into the VESC Tool app to improve the user experience.


FIRMWARE CHANGELOG


5.02 STABLE-3:

• Pre-configured battery settings:
  • Soft cutoffs
  • Overvoltage trip
  • Undervoltage trip
  • Cell count
  • Capacity
  • Current limit
• Tuned temperature limits
• More linear power level increments from the display
• Fixed App "Profiles"
• Faster boot to catch the Eggrider last level setting
• PAS keeps the motor spinning at minimum current to prevent chain slapping
• Tighter 12V rail monitoring
• New terminal command to read and store the default power level for display-less applications

VESC TOOL CHANGELOG

• Embed Luna BBSHD Ludi firmwares into the app for easier updating
• Add Motor Temperature gauge to the realtime page. Motor temp is the main limiting factor and it's good to keep it in check
• Fix FilePicker dialog used for datalogging that didn't work on some devices.
• Remove unused IMU realtime page that crashed on some devices

UPDATING THE FIRMWARE

Download the app installer here

Go to the FIRMWARE tab, select the correct firmware for your system depending on your battery type:

	52V Wolf	52V Dire Wolf	72V
Type	14s4p	14s6p	20s3p
Capacity	12Ah	21Ah	9Ah
Batt current	70A	105A	60A

Keep your Android device close to the controller and don't shut down your BBSHD while updating the custom firmware.


REQUIRED TOOLS

• BBSHD Ludicrous V2
• Android device

Have fun!

Okay. I will upload the Dire Wolf setting. Much appreciated

[BUD WHITE]

Just took the fat bike out for a 7 mile ride with the Dire Wolf uploaded settings and at my 3200 watt profile, this is more than enough power. Holy smokes. Even when I use my stock 1500 watt profile, this V2 controller is a beast. Torque could easily flip my bike up and over me if I don't lean forward and I am over 230lbs. I pushed it very hard in all profiles and went full throttle after starting from stop with PAS and the motor at 55 degrees isn't even warm to the touch. I remember pushing my stock controller BBSHD builds and the motor was hot enough to cook on. Great improvements here Luna Cycle crew. Cheers.

That's basically the email that Ludi v2 users received :)

Keep the feedback coming!

Cheers

Thanks Marcos.....great work......Still having PC BLE connection issues with MS Surface tablet/Windows 10. .... I have not successfully connected this device to my V2 yet. .... Does this new flash help with those issues? .... BTW...my android is connecting fine and I will use it to update firmware.

[marcos]

No, the windows problem lies between the windows version of vesc tool, the pc bluetooth driver and windows itself. The android app or the controller firmware that we updated are not connected to that issue.

[DaleH2]

Hello folks, proud new owner of the 72 volt Ludi V 2 !!!! Right off the snap I'm getting conflicting statements from Eric and the Luna sales guys. Eric says the Ludi will run on any Bafang display, while the Luna guys say I need an Eggrider. What say the group?

[marcos]

For 52V any display works.
For 72V batteries only the eggrider is fully supported. The bafang display i tested doesnt turn on when supplied with 12v and i found no way to communicate the battery level

[ncmired]

Hi - I've got a VESC/controller interface question. I've not had success connecting a Windows10 PC (via a generic Bluetooth USB plug) or via an Android10 tablet. My Andriod9 phone connection seems spotty or intermittent, so I don't want to try the software update with it.

So, I think that leaves the controller's micro-USB connection. Can I extend the controller connection out with a short pigtail, and plug it directly into the PC (and the windows VESC client hopefully will see the direct USB connection?) I assume this is the case, but am just checking.

P.S. if this was written up already and I missed it, apologies.

[marcos]

Yes, email support, Tony got those files a couple of days ago. I'll try to send you the file by PM when I get to the pc tonight. With your 14s9p I'd use the dire wolf firmware :)

[ncmired]

Thanks Marcos, but no rush for now as I can't even get the direct USB to connect (either via "Autoconnect" or via the only two serial ports (COM1 and 4) that show up). I'm not seeing (or hearing) a USB to serial COM port show up on the PC when I plug in the bike either (turned on or off).

The freshly purchased & downloaded Windows client is version 3.00, and the "Autoconnect" error popup says, "Could not autoconnect. Make sure that the USB cable is plugged in (it is) and the VESC is powered (it is)". The cable is (was?) known working. The manual connect errors with, "Could not read firmware version. Make sure the connected port really belongs to the VESC".

I'm plumb out of F'ing with IT patience right now, but I'll try again tomorrow. Whatever's going on wrong with my IT setup is my problem ...

[intramorph]

Please email Tony at support@lunacycle.com I will get you the files over email. It will be a lot easier that way. Just address it to "Tony"

[DaleH2]

Anyone have an idea on how to use the V2 with 72 volts no display? I believe it involves using a display plug and shorting the correct wires. I have no idea which wires so, help?

[marcos]

Yes, you would need a way to short the correct wires and store the initial power level setting in the controller. I'm not sure how exactly people would pull this off reliably though. In my mind it would involve using a cable from a donor display and adding a sort of waterproof switch. Maybe paxtana can jump in here

[paxtana]

Maybe this would work? This is what we do to bypass display with regular controller.



"Make a jumper out of a multi strand wire.. anything small enough to fit over one pin on the harness (like 20 ish AWG), please see the 3 pictures below. Jump the P+ and PL pins with the jumper. Don’t force the jumper in too much, if the insulation of the cable is too stiff, you can heat the tip of the wire with a flame to soften the insulation, it should slip right on it."

[DaleH2]

Ok, call me a simp but I'm having trouble with updating my firmware on my V2. Currently all it shows is VESC_default.bin, VESC_0005ohm.bin, and VESC_default_no_limits.bin. When, on my Android phone, I attempt to install the VESC tool it says " App not installed although it clearly is.

[DaleH2]

Dang never mind, I had to uninstall the old one first. The battery options are showing up now!

[marcos]

For future reference, Dale had installed the Original VESC Tool, not the Luna Edition VESC Tool we distribute.
That original vesc tool doesn't come with the luna firmwares, and if you flash a non-luna firmware you will brick the BLE connection and will be forced to re-flash it with the correct luna firmware over USB
