Someone brought this up on another forum and I thought I'd ask about it here to see what you guys think. This gizmo says it makes its improvements by stabilizing voltage fluctuations or something. Besides Sun, Apexi and some company named Pivot makes these too.

I've had trouble finding much information or discussion about these devices, so I was hoping some electronics experts here (Matt? ) could comment on whether this device has any merit or not.

Before anyone automatically raises the flag, it should be remembered that everyone once thought upgraded ground wires were bogus too... along with a few other mods.

i have groundwires and they do work; a slight but noticable effect. i'd hit this new box.
this seems nothing at all like an ebay fake electric supercharger snake-oil gimmik. this seems like a new mod i may do. it may work even better, in tandem, with the groundwires --less resistance and now a more uniform voltage under load. makes sense to me.

and now a word from our electrical engineers...

 

It's a scam. a few coils of wire inside a box, with a fuse on it for fire prevention. Then they sell it for $250 and call it a voltage stabilizer...
at most, all it can do it help rid the system of some RF interference due to the small inductance and capacitance it provides to stabilize the system. just like adding a large capacitor to your stereo, only much much much smaller results.

check out the 350Z forums for more info on it. they exposed these things a long time ago. HKS even sold one, and it's been taken off the market here after the guys at 350z motoring tore one apart and posted the pics online as being a scam.

 

-----there ya go.

i just got virtually scammed and am out a virtual $160 odd bucks.
i feel raped now. i think i'll go take a virtual shower.

 

Okay thanks for your input guys.

Matt, was this disassembly over at 350z Motoring? I registered but can't find the thread about it... what was the name of the stabilizer they took apart?

 

IF the device claimed to do what it said, it'd be good.

but. nope. doesn't.

scam.

thing is, if the issue of more consistent voltage under load was as simple as adding a box like this, why didn't the factory go ahead and do it anyway? moreover, why would the factory not consider it? also, why would the factory knowingly put out cars with problematic voltage output?

 

Cost factor.. adding additional grounds to an engine or one of these magic boxes is more money, and the car runs fine as-is. but they can run BETTER with an intake, exhaust, lightened pulleys, more aggressive ECU, ground kits, whatever... doesn't mean they come with them from the factory.

 

right. this is why the whole forum exists. it is just that if this box did what it claimed, it would be a good thing. but by what you have said, was found to be a wooden nickel.

off-topic sort of, but, then, in this vein, would an ignition amplifier like one of those msd boxes be of any use, then, creating a fatter spark? i've read numerous times on this board that the ignition system from the factory is fine, with seemingly few, if any, having done this mod. one who had done it a while back on the 2nd gen forum said it helped throttle response a bit, but that was about it.

 

If you've running turbo, NOS, or lots of NA mods, then it might be useful.. But too many people I've seen will just bolt one on and go and them wonder why it didn't do anything for them. for the vast majority of people on here, the factory ignition system is good enough. they're pretty beefy from the factory, as we've all said in the past.

 

MSD=multiple spark discharge I believe. Not fatter but 3 sparks to help light off the a/f.

 

well depending on the stock ignition it will put out a more powerful spark. For instance my mustang was an inductive spark system, but with the addition of the MSD box it changed it to a capacitive spark system.

The multiple sparks (because the ammount is not defined) is only below x rpm (its like 3600 or 4200rpm for example, it says the specific switch over in the manual, but I dont care enough to go read it ) after that point it switches over to just one spark.

They can help mileage and responsiveness, however like Matt said, you are probably not going to see much of a difference on the maxima. If you find a 6A for $40 or something then sure, why not, they look cool hehehehehe. Another tip if you just have to have one is the stangnet classifieds, they have good deals.

6A = standard box
6AL = same as 6A but has rubber mounts and a rev limiter
6BTM = 6A but has a timing retard control

I made a post 6months or so ago with directions on how to set them up with a VG. VE, not really going to happen.

Just for fun, here is my setup on the Mustang:
