What is the "accelerated stability" firmware in the Begode app?

[Lets Do Science]

@Freestyler Your method worked! check my edit, you the man!!

[Freestyler]

I'm glad it worked! 

cc @EMA for your friend if he did not already fix his wheel.

Then never do anything and dont ask us? Hundred of people update their wheels without issues. I told you to try, which was what I advise,not what you want me to tell you. 🤷

 

@letsdoscience glad it got fixed.

I'm surprised nobody has managed to determine what's different between these versions yet. Maybe I'll try both on my RST and see what the difference is.

I think this was answered in another thread actually. I’ll restate:

It affects the pedal behavior. It lifts your toes just slightly on acceleration, and lifts your heels slightly on braking. I guess to give you more leverage or something to push against.

In my experience, it doesn’t fix “pedal dipping” outright; as in what happens in corners or upon really hard braking/acceleration, but it does counteract it to an extent. I use it on my monster pro. I don’t use it on anything else so far.

Correct. Pedal behavior is the only change.

Also don't bother trying it in the high torque (c38) versions (RS & ex.n), as the firmwares are identical.

he tried without success, btw the wheel is fine becouse he received a new board.

[ i'll try to get the bricked board sooner or later ]

Ah, I see! Which firmware has less of this lifting behavior? I'm not a big fan of it (I love my old MSX firmware) so I may want to switch to "accelerated stability" if that lessens the counter-lifting. I've never updated the FW before, so I'm assuming it's on the regular version.

Ah, are the actually the same? Or is the difference just so slight you wouldn't be able to notice. Classic Begode moment either way lol.

[Freestyler]

The RS c38 and the RS c38 accelerated stability are literally the same firmware bit for bit. (Same MD5)

The ex.n c38 and the ex.n c38 have a different MD5, but binary diff analysis reveals no changes.

Maybe it's a mistake? c38 models were always touted as having firmer pedals anyway, so maybe the change is not needed.

Wow, that's hilarious. At least I don't need to test them now  By the way, is there a relatively easy method to grab the FW files from the Android app? I'm sure there isn't much I would be able to do much with them, but I am curious how people are extracting them from Begode/Veteran apps.

i've an exn c38 and both firmware feels the same to me, and they are softer compared to the c30 accelerated stability 

[EMA]

also i recently builded an RS c38 into an EXN shell, firmware feels softer compared to EXN

After you flash your wheel, the firmware is found in the Android/data cache folder.

That confirms it then.

I can probably port the pedal behaviour from ex.n / RS c30 to RS c38 if you are bold enough to try it.

the EXN Board looks identical to the RS one, minus the larger capacitors, maybe this explains the stiffer pedals?

Good point. People that install extra capacitors, report stiffer pedals. We installed one on our friend's RS.

7500μf compared to 2x ~650μf on the controller.

I have 2 x 560μf not 650

Yeah the wheel feels like i can push it a bit more.. See pics.. 

I've put some foam blocks under it, to the left, to secure it  

And yes, the "stability" is something you feel while riding..

[goatman]

you taped 1-750 to the battery pack and connected it with a xt60 splitter at the control board leads?

[Freestyler]

Yes, but it is 7500 and not 750. Super capacitor territory

More information in our forum: 

The anti-spark cable (which is just a xt-90 from what I understand) is super helpful to avoid sparks when connecting the batteries.

I've been meaning to reply to @goatman about it, but then i saw @Freestyler answer, thank you! 😋

It's 7500μF quite huge but as advertised (no bias here)

• - more rigid pedals,
• - more complex cutoff,
• - eliminating the" floating " of the pedals on the comb,
• - a longer battery life.

thanks, ill have to order one to get rid of some volt sag

Doesn't save much but that extra oumph is there, you know!

Odd, I have a c38 exn as well and stock firmware had very noticeable pedal dip while turning. The accelerated stability I notice it much less.

I thought it was crucial for the caps’ operation to have them as close to the board/mosfets as possible. I could be wrong though.

Yes - near to all the mosfets would be perfect, but every "potent" buffer "somewhere" helps to smoothen the pwm pulses.

So the li ion cells gets less burdened with the high pulsed phase currents and the mosfets/motor get a bit better current supply (->more pedal stability).

One should be carefull about where to place such capacitors as they can get very hot and be one of the weak links...
