Luna BBSHD Ludicrous V2 controller documentation

[BUD WHITE]

Update: I have PAS working on all 3 of my profiles(stock 1500watts, V1 2500 watts, V2 4500 watts). I set my stock profile to 100% PAS current and the other 2 profiles at 85% PAS current(just to be safe) with the Eggrider display set at level 9 and the bike works like a charm. The throttle I have disconnected, because it will break my brand new upgraded motor shaft at this point. The fat bike has the 42 tooth chainring and I keep it on the 28 tooth for the rear. My body weight is 230lbs. and bike is roughly 70 lbs. with big 27ah triangle battery.

Still having issues connecting VESC tool through PC. Android no problem. I have tried my new MS Surface PC tablet w/ keyboard as well as my 4-5 yr old HP PC laptop Win 10.

is there anything special here?...It’s not populating my VESC on scan from the tool.

Hello StvMan,
I have got the V2 running great with PAS and throttle on all of my profiles while on a stand, but when I sit on the bike and try to ride it, the motor is bogged down and wants to break my shaft. PAS will not work either. I am trying to work out the kinks with Marcos on a private chat. I honestly think it could be my fat bike tires with 42 tooth chainring, or the Eggrider display. Tonight I am switching to my mighty Luna chainring and will use my stock BBSHD profile(1500 watts and 100% PAS on VESC app). If that does not work, I will try switching out displays and going with the stock Bafang display.

Bud....I am curious, what was the solution to your problem? ...Steve

[BUD WHITE]

Excellent info again Marcos. Thanks.

Level 9 will be this weekend!!!......thanks for the tips on the PC tool for VESC.

As to that, I am still having trouble connecting my PC (Surface Tablet) to the BLE. The BLE app that I tried made some progress but ultimately didn’t work. I will try a conventional, full laptop PC to see if it will connect. No problems with my android though.

Now I'm keen to see you trying level 9!

Levels also affect the amount of pseudo-field weakening so level 9 will have a bit more end speed than level 6.

For now all motor configs are locked, but you can set ramping curves in 2 ways (this is generic VESC stuff):
* From APP->ADC (this is the throttle) -> General -> Positive ramping time. This will make the throttle response smoother and slower. Don't go below 0.3s, the time I tried a lower value I destroyed the nylon gear in less than 3 seconds, had to upgrade to a peek gear.
* APP -> PAS->Positive/Negative ramping times do the same for PAS.

You can also change the throttle mapping from APP->ADC->Throttle Curve. For this I recommend using the PC version of VESC tool, only because you see a nice x,y plot showing the curve shape which is not shown in the android app.

Marcos, Gary, Kyle, and the rest of the Luna Team......the Ludi V2 controller is awesome!!! ....

I just finished pairing it up with my BBSHD and setting the PAS back to 0% using the VESC tool for my first test ride.

I started at level 1 and progressed through level 6 (holding off on 7-9 for now). The power delivery is impressive, with a clear sense of the field weakening effect as I got further into the throttle (at least that’s what I assume I am feeling...it definitely has more power range than the V1....and that’s saying a lot.).

These test runs were on my flat neighborhood streets...I am looking forward to getting out on the single-track trails to see how the torque feels underfoot.

Still exploring the VESC tool to see what limits I can tweak to add a bit more protection until I am more familiar the V2’s huge power potential (hopefully there is the ability to set Limit Amps, soft start/ramp curves, etc).

Anyways....awesome controller guys!!! .....Thank you, Steve

Thank you Marcos for the information.
Thank you Jasdidit.

[BUD WHITE]

was able to set the power levels to the 9 option on the Eggrider display. Thanks again Jasdidit.

The gear sensor was never disconnected during uninstall of V1 controller and install of V2 controller. It is separate from controller install.

[BUD WHITE]

Yes I have tried all power levels both offroad and road. Works perfect on stand, but not while actually trying to ride. The connections are all correct.

[marcos]

Tried increasing the power level? Level 1 (10%) could be too weak?
Have you installed the phase wires in the correct order following the colors?

[BUD WHITE]

Okay, so my V2 powered fat bike with a 52 volt 27ah Sony VTC6 cell with 70 amp continuous works perfectly on my stand with PAS and throttle both in offroad and road mode on the eggrider display. However, once I sit on it and try to ride, the motor bogs down and doesn't even want to move when I hit the throttle. When I pedal it, there is no electrical power. I am stumped at the moment.

[StvMan]

I don’t believe there is a gear sensor connector on the current V2..... mine doesn’t....Steve
