The manual talks about being able to use taller gears. How does 72 volt vs. 52 volt effect this matrix. My tests find the 72 volt can work with a slightly taller gear than 52.

Um, I don't suggest taller gear, in fact at 72V for the same end speed you can use a lower gear because motor wants to spin faster delivering same power with less motor heating. Having said so, the reason you can use a taller gear is likely because your batt voltage is not sagging that low which makes your phase current (torque) more consistent. Just watch out for motor temperature if you beat it at low rpm.

I am not getting the speedometer to work correctly. It asks for the diameter of the wheel, but the speed reads faster than it really is. Could VESC be asking for the radius?Comment

Perhaps you typed inches but the app is set in metric. VESC typically defaults to metric but you can change it to imperial in the app settings. In the desktop version of vesc tool I'm not sure if the logs can be shown in mph.
This is from the very last log I have, GPS speed and wheel speed should be close:

I recently installed my new Ludicrous V2 to the BBSHD motor. I connected the battery (52v GA13.5ahWolf Pack) and turned on the display (Luna 750c). At first everything worked fine but then the motor quit working but there were no error codes on the display. I disconnected and reconnected the battery but this time the connection made a popping sound and the display still showed no error codes. I bought the Ludicrous V2 because I thought it was a PLUG & PLAY part. I'm mechanically inclined but have little tech savvy and I own no android devices. Any thoughts?

I found the problem. The male spade of the yellow wire slipped in between the plastic insulation and the connector. It looked connected but it was not. Once I got these fat fingers into the controller it all came together. ThanksComment

Greetings Everyone! I’m shooting for a winter rebuild/upgrade marathon (while I pout and wait for spring in the mountains lol). I just sent an email to Luna to ask manager approval for the V2 ludicrous controller. I’ve been researching all the options for the BBSHD and think this is by far the best product!
Im upgrading the bms to 60amp on my 52v pack. Also going to pick up some good grease and the steel replacement gear.
What else should be beefed up if possible?Last edited by Rolocretaw; 10-03-2021, 06:49 PM.Comment

Hi all! After 1 year with my BBSHD stock controller I would like to slightly increase the maximum current to 40-50A (my BMS can handle up tp 60A). I've read the Luna manual and it looks promising! I could even stay with my Eggrider v2 display.
Before I go for the approval, I have one short question:
Eggrider has a feature that lets me quickly change to a pseudo-legal mode by pushing a button on the display. Then the system stays locked in this mode and can be unlocked through the Android app only (Which is exactly what I want).
Question: Is this still possible with Luna + Eggrider?
I understand that the VESC app is the preferred way to modify Luna-settings, however I'm not sure if the Eggrider app is still an (maybe additional) option.
Thanks!Comment

You can see controller realtime data in your eggrider, but your eggrider can't program the ludi v2 controller settings like currents, power, speed, so that button on the eggrider display won't do much. The eggrider configuration packet is super super small comparing to a vesc config packet, I'd rather stay on the vesc path because its way more flexible (temperature limits, acceleration ramps, etc)
The closest thing would be to open the app, go to the street legal profile and tap write settings.

HAve a question, I just install the ludi2 , and the motor get to hot to fast, is that normal???
I ride for about 10 blocks and it shut down because the temperature , I dont know if I doing something wrong , or is the way it work
Any advice??Comment

Best way is to avoid going full throttle at low motor RPM as it can drive the full 150Amps through the motor., for that you should try to use short gears. Also too short gearing can overheat it by driving 30A of field weakening for a very long time. Just keep in mind that the motor can do 30A continuous and you have 150A at your disposal in throttle. If you can post logs we can take a look!

marcos on to the masters ,so my ludi2 get to hot, and I was thinking , when I did the installation , one of the plus is the one in the white silicone, which I need to "cut it" to get the switch out and plug the new switch for ludi2, up top here all good.
Now, can be the heat from the motor come to the controller they that "whole" on the silicone??? and make it go hotter faster?? what do you think?? I should re open it and add silicone there??
or I am over thinking??

A long time ago (like, I swear it was last nov or dec) I was out on a waiting list for lido c2 for my galaxy that already has regular. V1. No one told me it was available. So, reading this post I assume I can get it now. Supposedly I was approved and on a list-when it was available. I kind of forgot about it and still want it. Is it I. Stock now and available? Gary was the one that had me on a list at the time.Comment

The spell checker on this stupidi phone is off the hook. Hope you get what I’m asking above.Comment

Ok will do thank youComment

With great power comes great responsibility. In our case: to watch the heat.
Marcos nailed a battle I am in when he said: "Best way is to avoid going full throttle at low motor RPM as it can drive the full 150Amps through the motor., for that you should try to use short gears. Also too short gearing can overheat it by driving 30A of field weakening for a very long time."
The logs teach me, but when riding I need 2 data points on the display. The heat is there and is the most important. However what should I look at to know when I hit field weakening?
Can we add something to the ride page in VESC? Perhaps the display could go plaid?
