Re: Apexi super voltage stabilizer 5.7

Just my 2 cents. I have been in the Electronics industry for over 20 years. Most of you own a computer (unless you are posting on this forum with an abacus), so ask yourself this question: Do I have a surge suppressor on my PC? If so, why? There is as much computing power in our vehicles as in a small tablet PC, much more than when vehicles first started sporting PCM/ECM's. Now if you want clean power for your PC, wouldn't you want clean power for your vehicle? These devices are really just that, power filters. They store a capacitive charge from the battery and absorb nasty spikes, also supplementing power levels when there is a drain. Constant supply voltage is CRITICAL for all electronic components. Ground is just a s critical. The Apexi has just included a ground bus and some fancy marketing. One of the cheap capacitive filters on eBay will also work as long as it has enough "capacitance". The grounding you can do yourself. I just ordered one of the cheapies myself. The TB ground wire mod is along the same concept. And yes, you can protect your computer from nasty voltage spikes with a simple capacitor bank. The main difference here is that on your PC it is protecting and filtering 120vAC and on a vehicle it is 12vDC (Capacitors don't give a rat's butt about current).

Re: Apexi super voltage stabilizer 5.7

I Read some of this this morning and did some research and here is a article I found while looking around
http://www.importtuner.com/tech/impp...n/viewall.html

I believe it all depends on the car installed. I think it may do some good with systems and lights but doubt it adds any noticeable HP . I believe the grounding is a good thing though. The clear and quicker path to ground is always better

Just my 2 cents

Re: Apexi super voltage stabilizer 5.7

MY 2 cents. Every single person arguing about this does not have one. Only if you install one will you then have a viable opinion, and will know how well it works and how much better the Hemi responds.

Re: Apexi super voltage stabilizer 5.7

I would be willing to try one , Not the Apexi due to the $209 dollar cost. Let me look around.

Here is another write up. By a "Independent " tester
It is listed about 2/3rd s down the page

Re: Apexi super voltage stabilizer 5.7

It is quite possible that a HP gain does occur. More from refined power to the electronics than stable power providing direct HP. If this is the case (which I truly believe) then results will vary based upon the quality of your +12v power. Poor battery, alternator, bad contacts, bad ground can all have an adverse effect. I have seen a bad alternator cause a low voltage condition that caused the rear wiper blade to randomly turn on when the radio was turned on (mid 80's caravan). Bad power can do some crazy stuff. Good power makes things work they way they are designed. I'm not saying it is snake oil, it's not. Power filtering is something that manufacturers are not designing into modern day vehicles when they have some serious computing power and I can't understand why. Well, yes I can, I never really even thought about it until this thread, but from my experience, it makes total sense. I don't think it's worth $209, but I will verify that myself this weekend when I get home and install the cheapie. The last car that I heavily modded had to have the TPS slotted and adjusted just to get the correct voltage readings that the FSM stated. It too was plagued by bad ground problems.

Re: Apexi super voltage stabilizer 5.7

So I received the cheapie unit from ebay. $15 and a total POS. I opened it up before doing anything and it's a complete joke. I am now pursuing step 2 which is building my own filter with a grounding bus. I have the plans and will be sourcing the parts throughout the week. It should be quite simple, power filtering is a easy process. I just wish that I had an oscilloscope to prove my theory. Remember, all I am after is noise free +12vDC noise free power and no spikes. I suspect that as in all electronics, good power equals good results form the sensors. Good results should equal accurate feedback to the ECM and proper engine management regardless of the tune.

Looking forward to your results and your potential for commercial production depending on your positive results!

Re: Apexi super voltage stabilizer 5.7

I'm not an electronics expert so I am asking a question.
Is not a good ground a good ground?
I understand a conditioned power source for longer life, and consistent/peak performance of electronics. So why not do it on the positive side? Do it off the battery before power reaches any electronics? What if you added something at the alternator so even the battery got conditioned power?
I dont know, just asking. I would not expect any real gains, just a happier system which is always a good thing.

I had one on my Jeep and am arguing it....well not arguing it, but think it's questionable at best.

I had the wire and some connectors so made a kit myself....things did seem a little smoother but that could simply be from the battery being disconnected and the adaptives resetting, could be all mental...thinking I did something so I should look for the result.
There is a thread on LXForums, someone there makes grounding kits, he has dyno charts and etc...
As for the throttle body grounding....the electronics in the throttle body are isolated from the housing so connecting a wire to it will not do anything.
If you're running grounding wires...don't forget the transmission.

Did a little googling....supposedly this kit is made by NRG, and a little search of NRG gave me this post on s20nation.com

Quote:
I bought the NRG voltage stabilizer (compact version) I must say it really does work. It doesn't necessarily boost HP but Import tuner mag did dyno 3whp gain on a 2000 Civic Si.

Things i have noticed are my windows roll up easier/quicker. Quicker starts. After sitting for a few days my car would crank over real slow. This has been almost 100% eliminated due to installing the NRG voltage stabilizer. Better throttle response.

NRG claims that it will -

~ Battery Lifespan will become longer
~ Stabilize Idling
~ Lesser Engine Noise
~ Improves Sound effect
~ Improves Engine Torque
~ Improves Engine Responses
~ Improves Fuel Consumption
~ Improves Headlamp Brightness
~ Quicker and Easier Engine Start
My windows roll-up easier / quicker? Really? LMAO

Re: Apexi super voltage stabilizer 5.7

Most of the claims are pure marketing hype. All can be traced back to noisy power causing inconsistent sensor readings.

IF you do not have noisy power in your vehicle, you WON'T see any benefit at all from power conditioning (such as with a new vehicle).

The filter will be connected directly to the battery which will basically "absorb" all of the noise from the alternator or most anywhere else in the circuit. This is the same as adding a capacitor to your fuse box to quite the whine in a HIFI audio system, only this is for the entire vehicle. Granted, the ECM does have some power filtering built into it, but so does your PC and it is still at risk without a surge suppressor.

I believe the throttle body grounding to work BECAUSE it is isolated allowing a static charge to build up on the TB itself which can induce noise into the ECM feedback.

I do wish I still had my old oscilloscope so I could take some readings and verify my hunches. Oh well, to trial and error we go!

Radio Shack is my only supplier around here and they suck. They wanted over $5 per cap, I think not! They did have some of the stuff that I needed. Now off to the web!

BTW, if I can prove my theory, I doubt that I will attempt any commercial production. I highly prefer "open source" technology (isn't that what this forum is all about?). I will gladly share and assist anyone who would like to attempt the same once I am finished. I'm having a hard enough time getting a pic for my signature! LOL

Re: Apexi super voltage stabilizer 5.7

The Hemi loves the Apexi, and it is a well built unit that does much more than just grounding. Building or buying something cheap will not net similar results, guaranteed. The dyno gains of 6-14 WHP measured using the Apexi unit from the magazines were all done on low power 4 cylinder engines. i.e. 240sx, Civic del sol, etc.., about 1/3 the power of the 5.7. I've also tried CAI, and had a Magnaflow exhaust, which are both a total waste of money and do nothing for performance in comparison.
