God Mod- Buyer Beware.

[Funky]

I should start selling my own shit. (Literally shit.) I bet some people would buy it?

Best part, if someone ask how i could afford my new EUC. I will tell them, that i bought it with my doo-doo.

sure, to the ignorant eye there's no special sauce... common folk cannot understand the science and only see 'wires'. This is a bit of a long read, but it explains in detail how a 1 meter RCA audio patch cable is processed to make it superior enough to justify its 61CAD cost. Each. I do understand that high temperature treated cables are even better but they're quite spendy indeed (and difficult to find).

The crucial paragraph that explains it all concisely.

 

How does it work?
Cryogenic Processing of metal at temperatures at or below -195 C causes molecular changes to occur. As metal objects cool, they shrink. With the -195 C temperature and shrinkage that results from LN2 immersion, the crystal boundaries of metal conductors align more closely with one another increasing conductivity and reducing noise. The tightened grain structure stays intact through the slow warming process and is stable at room temperature and in the case of vacuum tubes, remains stable at operating temperature. The change is permanent.

i can definitely understand the idea of some secret being hidden in plain sight. but from my deconstruction, its simple tinned copper wire used for the connection and the capacitors are wired together with a solid unsleeved copper wire. nothing fancy. Not to mention that they where originally sold for 75$ and now the price is jacked up to 300$

You intended this as an example of a bunch of bs that sounds good to try to justify price when the effect for the end application (audio signal transmission) is basically zero but it convinces people to part with their money, right? I think that went over some people's heads.

Yes, it was a poke at things that don't quite make sense but might, if testimonials are available, seem legit. Or at least, worth a try? I used the audio cable example because a number of years ago there were 'specially heated' cables that promised similar benefits, only they were literally 5000USD. You did get a "set" of them but the improvement they promised was well below the accepted threshold of discrimination of the human hearing system.

BUT, most audio aficionados can hear things I can't so I have to give them that. Some things fall into the "if it melts your butter, go for it" category. I can't convince you otherwise, and honestly if frozen or baked cables make you happy then who am I to argue.

My only beef with GodMod is adding stuff to a control system without knowledge and at least some level of peer review can go very badly. It's one thing if your stereo really isn't actually any more accurate than it was before your cable mod, it's entirely another if someone thinks they can dart in front of that car... and they can't.

Don't get me wrong here. Stabilizing the battery voltage is generally a good thing and if there was physical room and we would put up with the price increase I'd bet we'd see something similar to GodMod pre-installed. My guess is that whatever improvement you get was deemed insufficient to justify the cost. But I don't know that!

If you like what it promises, buy it. Just be careful because it might not be a JesusMod—it might just be a GodMod. IIRC it's Jesus that saves, and God has a vengeful streak.

And to continue that analogy, I wonder if it is called the God mod because its effects are largely imaginary ?

Artist's Shit

Artist's Shit (Italian: Merda d'artista) is a 1961 artwork by the Italian artist Piero Manzoni. The work consists of 90 tin cans, each reportedly filled with 30 grams (1.1 oz) of faeces, and measuring 4.8 by 6.5 centimetres (1.9 in × 2.6 in), with a label in Italian, English, French, and German stating:

Artist's Shit
Contents 30 gr net
Freshly preserved
Produced and tinned
in May 1961

 

A tin was sold for €124,000 at Sotheby's on May 23, 2007.^[6] In October 2008, tin 83 was offered for sale at Sotheby's with an estimate of £50,000–70,000. It sold for £97,250. On October 16, 2015, tin 54 was sold at Christies for £182,500. In August 2016, at an art auction in Milan, one of the tins sold for a new record of €275,000, including auction fees.^[7] The tins were originally to be valued according to their equivalent weight in gold – $37 each in 1961 – with the price fluctuating according to the market.^[3]

And then they are used to listen to music in an untreated room that has peaks and dips in the frequency response worth up to +-10dB. And music whose makers never ever use any of that bull themselves. 

 Perspective couldn’t be any more out of whack than it is in the Hifi world. A week ago I got to listen to a $80’000 pair of speakers in a Hifi shop. Result: my $1500 speakers play better in my lightly treated room than the expensive ones did in the heavily treated shop.

 Don’t buy Hifi, buy pro audio if you want actual good fidelity for a fraction of the price. Audio pros don’t waste a single penny for any kind of bull.

 My favorite hifism is still the $485 wooden volume knob that was said to have a way better sound. Not a volume pot, just the knob that you put on top of it. Like, there are clear technical reasons why a Godmod should at least change things. A wooden knob doesn’t even try.

Videos will be slightly delayed here as i need to make some last minute additions and i got called in to work today. 

But to give a quick synopsis of my findings, subjectively there is a slight difference to the ride feel using the capacitor mod. Empirically however it failed all my tests. 

Go big or go home when installing a mod, as my larger mod subjectively made more of a difference. But i would take my 600$ and buy a 24s2p samsung 50e battery pack 10 times out of 10 over a 600$ god mod. 

hopefully will have the videos out tommorow

Wasn't even supersized about findings.  

More surprised i would be, if there have been difference.

dont forget that the weigth, mass and material of the wooden knob will prevent high and especially low pitch volumen bursts vibrations to reach inside the pot, and thereby have a stabilizing effect on the continuous and undistorted music delivered to the innocent listener.

yes i really mean it  I mean, mean. oh and now that i took the time to read what's in the link i can see, that the claims are exactly the same,funny😁

Will you now add capacitors directly to the board?

Not using your big capacitors, but using the same ones already on the board. You just have to solder onto the existing leads.

no , A) there really isnt much room in the control box of the ex20 and i would need to add extensions to make them fit. 

B ) i dont really want to modify the control board in any type of permanent fasion like that.

C) i dont see what difference it would make to use smaller capacitors that are still just wired in parralel as far as i understand it. we can safely assume they are not wired in series to the batteries since there are 2 seperate 160v capacitors on the board, and wiring them to 320v makes no sense they would be tragically inefficient that way. 

i know there is some effect increase to be had by reducing the resistance between the capacotors and the power delivery but considering im using capacitors 10x stronger than the ones on the board theres no way im losing anywhere near that much efficiency to the wiring

In the latest marketing material, the company claims that the big one ($600) provides benefits comparable to high drain cells packs.

That's a claim that is obviously false and would be easy to disprove (with the ability to compare between two identical wheels each equipped with high capacity or high drain cells.
Under load, Samsung 40T or Molicel P42A will drop a whole lot less voltage than high capacity cells like Samsung 50E due to lower internal resistance, and accumulate a lot less sag as well during continuous drain.

For performance and safety, high drain cells are the real upgrade that works. They'll even increase significantly the risk of surviving a catastrophic event like one of the packs breaking down while riding at high speed, which makes redundancy effective. That's the reason why Jason at eWheels is so focused on distributing high drain cells variants of existing EUCs. Instead, capacitor mods will provide zero help here.

Based on your synopsis, I may suggest one conclusion to your investigation , that would be:
Use your money to buy or upgrade to high drain cell variants if desired. That'll make a practical, measurable, significant difference on everything important that godmod claims: like increase in safety margin and acceleration, where godmod will make virtually none to exactly none - depending on the platform.

Ironically, the only thing godmod does on some wheels and might be highly appreciated is making pedals stiffer, as a hardware hack for the pedal mode tunings. Yet it's not even mentioned in the marketing material.

Putting supercaps in series needs load balancing like bms do. Otherwise it will lead to problems similar to charging li ion cell packs once they age/degrade.

Also such amounts of capacities with low esr could maybe lead to serious overburdening of the controller - they could rely on not instant current availability.

As low speed torque could be just intentionaly limited by firmware to protect the mosfets and wires.

Putting some farads  inbetween is some real major intervention!

Adding some milli farads near the mosfets and/or the controller already greatly increases peak current availability without endangering the design.

Question: Do low ESR capacitors of the size like GOD MOD even exist? If the capacitors would not be low ESR I cannot imagine them of any use...

I meant to say, personally I think the only way of testing caps conclusively is in a dyno rig, anything else is a bit subjective to my liking. But we'll see what Kev has to say.
