OK, i did a search. HVS stands for Hyper Voltage System.
Hyper is the key word because it sounds cool :-).
Noone explains how exactly it works. There is a lot of words about "cleaner voltage", but why is it better than "dirty voltage".
And how would it add horsepower? Why does it cost few hundred dollars while components cost $10 or less?

My opinion is that some people will buy those kits no matter what because a "mod bug" bit them.

Of course the materials cost less. Think about how people made a muffler. It is simply a piece of aluminum that is wrapped around and it won't cost anything over 100 but why would it sell for over $500.

The HVS actually stores excess electricity that is not used by the battery. When a huge amount of electricity is needed (full throttle.....), the HVS releases those electricity so the whole electrical system is more stable thus increasing the travelling rate of elctricity.

 

now the BIG question, can we make our own?

Subrobo,

Can you provide the wiring diagram or explain where the three redish coloured wires conect to.

This kit looks like a bunch of hipe. The only significant piece that I can see is the large capacitor which you can get from Radio Shack for $5. It's only purpose is to slow down or smooth out fluctuations in voltage. It cannot and I repeat cannot increase horsepower. That is just a bunch of BS.

I have a 2.0 Farad capacitor in my car to stablize the voltage going into my amp and it's friggen huge. It's about 10" high and about 6" wide. It's job is to reduce spikes/valleys in voltage so you don't get a hugh draw on the alternator.

I must be getting tons more horsepower!!! LMFAO.

Couple questions:
1) What would consume "huge amount of electricity" when you press pedal to the floor?
2) What is a "travelling rate of electricity" (I only know two characteristics of electricity: voltage and current) ?. And how would it increase HP?

1) ECU, TCU, drive by wire throttle, other electronics in the car
2) reduce the time current has to travel from point A to point B

 

"increasing the travelling rate of elctricity"

FYI, the traveling rate of electricity is a universal constant. Only now is the speed of light becoming a significant factor in computer processors, and even then only in the highest-end super Crays containing mulit-billions of transistors and other critical-path components. The electrical systems in the G aren't even dinosaurs in comparison, they're more like single-celled organisms, and just barely that.

I'm not sure what this mod is supposed to do, and I AM a semiconductor engineer.

Regarding an explanation of why this type of product can be so hot, such that lots of people are buying them, well that's simply human nature. It's easy to install, has a technical but ambiguous explanation, and the placebo effect does the rest. Lots of money was made on snake-oil as well, it's possibly the same thing.

If anyone has any credible proof it does anything, or even a reasonable explanation of how it can, I'm all ears. I'm not saying the benefits aren't real, I just haven't seen any credible data regarding power gains, and that should make everyone suspicious.

Wow, we apparently are in a time warp. Electrons flow at a constant rate. By reducing the resistance to current flow you can reduce the amount of heat generated, not speed up the electrons. Heh.

I would love to see anyone really offer a scientific, real-world analysis of these products. An engine is an air pump; the more air going in, the more fuel that can be added, and the more power the fuel and air combustion can produce.

What electricity gives us in an engine is (a) power to run all the electronics, and (b) an easy way to ignite the fuel/air mixture. For (a) all you need is something that doesn't make the ECU smoke or lock up -- "cleaner" ground flow != more horsepower from a "smarter" computer. For (b), all you need is a spark. If you want better combustion then work on the breathing (intake, valves), more precise fuel metering and atomizing, etc.

But if you buy the HyperGrounding stuff because the cables look cool, well, that's different.

The way I see this then is the potential that it can reduce the peak draw from the battery/alternator. Which inturn can merit some additonal HP if it actually does reduce the peak load. However, if the damned thing costs $400, you can just as simply wire in a Large capacitor made for an amp and get the same results if not better results for loads less.

And something like this wouldn;t change the efficiency of the electrical system, only it would allow the alternator to put out a lower, constant stream of current vs having spikes when the current draw from the various electronics gets high. But considering that the various electronics do not appear to be a huge draw like a car stereo amp can be, I doubt it will have a profound effect on performance.

 

The ecu constantly measures the voltage [battery and alternator] because the injectors are connected directly to battery [+12 volt bus] and are grounded by individual in ecu transistors.

Compenstating for even 0.05 volt changes is necessary BECAUSE the injector opening time [ramp up to open] varies with voltage. Really critical at idle from summer to winter to fall when very little head light or fan/AC loads are used.
Cold cranking may drop everything to 9 volts vs 13.2 nominal.
The ecu may triple the cranking open time to compensate for voltages.
At idle the ramp up to open maybe 85% of the total opening time vs at WOT 4400 rpm it may be only 10%!

Same with ignition coils but less critical a volt gets multipled by 2000 times.............so whether 25,000 or 23,000 volts is less critical.

The ecu has precise voltage regulators to supply + 5.00000 volts to many sensors so the results [sensor outputs] are very very accurate.

Studying how ecu operate and do what is the only way you can differentiate the bull and worthless mods from some that might help a tiny bit.

 

This mod sounds interesting as the tornado.

 

So Q, seems like these same principles might apply to whether or not a "grounding kit" may or may not be effective. What implications might ground have on the TCU?
