DIY VOLT STABLILZER

[Fuelsaver]

just installed VS recently fr bro CW7978589 - noted engine starting 1-2 cranks lesser (improved CCA?), batt voltage slight up by 0.x, even slightly colder aircon (now can turn to 24.5 to 25 deg c instead of 24 after grounding), engine notes sounded smoother from idling to 5+k rpm but no increased performance, ICE bass slight improvement. i can't explain these gains but only think there's something electrically different.

 

coincidentally, it appeared there was slight improvement in FC (12.5km/l; previously suffered fr poor FC of sub 11km/l for a month after v-power & mayb also due to ICE sapping more power fr batt causing less precise / stable signal fr ECU? then reverted to slightly normal of 11.x constantly) durin today's top up, but might also be subject to fluctuations & many other external factors. unless there is constant achieving of such FC, this area's still inconclusive.

 

some can say above is rubbish but at least i'm truthful about no performance gain by installing such a product. perhaps electrically efficient translates to more precise & consistent / stable electrical signals, esp fr ECU?

1) Unless his VS has a bridge and amplifier I doubt your battery voltage will go up in clean voltage.

 

2) It was raining on and off recently so no prizes for cold air con.

 

3) Sound smoother is use oscilloscope to check the wavelength?

 

4) Improvement of 1.5/11 is 13%. That's not a 'slight' improvement. Hence I want to install 10-20 units.

If u r AVIVA customer, VOLT STABLILZER will VOID your insurance policy.

Either change insurance company or take it out

Don't worry. I'm not with Aviva.

 

Nor will I stay with any insurance company which states this dumb ass condition on top of the already draconic T&C already existing.

even if 1 is with aviva and had an accident, what is the difficulties of asking your mechinic to take out before the inspector comes, and the inspectors usually comes on following day.

 

my friend added in turbo, got accident, still got time to take out the snail and and full claim....

[Cwx7978589]

Can I get 20 PCs??

 

My FC is 14.0

 

So if 20 pcs at 5% compounded, I would get 37.15 km/L.

 

If at 10% .....FWAH.... 94.18...

 

Can make genting at 10Ls and back haven't reach half tank at worst case!!!

 

All for 4k.. Very worthy mod..

 

Hi, bro, please donnot split hairs

cannot imagine like this even you math quite good

thanks bro. are you the last car show at the picture?

1 - benefit of doubt given

 

2 - no rain these few days at my area + hot day too; other days w or w/o rain & w/o vs didnt feel that cold either

 

3 - no equipment, can help?

 

4 - as i've said, it is coincidental - not conclusive

[Fuelsaver]

thanks bro. are you the last car show at the picture?

yup.

bro u r very wrong, u have to call aviva immediately, else u will also void your insurance

that is their term n condition

guess the reason is to check immediately if u have mod, they know if let u have the time, u will remove the mod.

watch the movie I am not stupid ....hehe just kidding

 

aviva so cunning, u think they will let u have time to remove mod?

Have install for Toyota Wish?

Hi bro, only install 2 vois car .any car have 12v battery can install

[Bystander50]

Nope never measured the voltage.

 

Actually I had no problems with my GPS, In-car Cam, and Nokia Phones. At that time only iphone got charging problem. I think iphone 4 really needs full 12v for the power to go in while other devices don't.

 

I don't think your Iphone needs 12v power to charge.

Based on USB standards, the max is 5V, 0.5A.

 

If you charge on your laptop using the same cable, i also draws 5V from the USB port.

 

Check your charger, it may be faulty.

 

[Bystander50]

sorry bro cannot ,the VS cost quite high so cannot trade in , and i already have 2 set pivot , for study

 

Care to share what brand of capicators and their origin of manufacture are u using?

Hi bro . I used Nippon chemical cop and nichicon 105 degree capacitor

Its actually very very normal for ICE to improve after installing voltage stabiliser.

 

This is because the voltage produced from voltage regulator from the alternator actually fluctuates with RPM and AC/DC conversion itself + noise from engine etc.

 

There are some websites that claimed the battery is actually a large capacitor and will act as a VS. However, this is not the case. The batt can only do so for certain frequencies of voltage fluctuations (mainly lower frequencies). High frequencies cannot be smooth out by the battery. Thats why VS is needed.

 

Thats all why you need many capacitors of different sizes in VS. Bigger values take care of lower frequencies while smaller ones take care of higher frequencies.

 

As for why improvement in power can improve ICE performance, I leave it to the audiophiles to explain.

 

 

Why clean power is important? Everything you have in your car depends on it. Your throttle sensor depends on voltage changes (to determine throttle position), your O2 sensor depends on voltage readings to determine amt of O2. Your Air flow sensor (or hot film sensor), your MAP sensor.

 

In case you are wondering how a VS can improve ignition. Its simple, when the ignition coil fires, there is always a detectable voltage drop (if you have an oscilloscope you can see it). A VS will reduce this drop hence improving the ignition performance.

 

If you really want to experiment, just get ignitor + coil + spark plug + 12V battery to experiment how putting a capacitor in parallel to the 12V batt can actually cause the spark to become stronger. I have play with it before thus I know the benefits.

 

If you really need more spark performance, you can opt for CDI then you can increase your spark gap by a huge amount. But its not really needed for NA or lightly boosted cars.

[Mona-vie]

Btw, one may wonder why car manufacturers don't use or add VS to the car even though its great device.

 

Well, one have to think about reliability and cost. Electrolytic capacitors are not exactly reliable devices (when it comes to high temp conditions) and they do not have very long life span.

 

They degrade over time and with temp. Electrolyte also evaporate over time (even though they are rightly sealed).

 

I do recall condensers used in old cars back then using breaker point ignition systems. But now solid state breakerless systems no longer need it.

 

Typical E-Caps are rated at 85-105C for around 2000 hours. Thats not very long if if you consider the fact that cars can last well over 10yrs and engine bays easily get 60-70C and get -20-30C in cold weather (during winter). So do you want to risk having devices that could compromise reliability of the car? Also have to drive thru standing water, light floods etc.

 

Of course, we don't really need to bother about winter in SG or blown capacitors since we can change it easily. But would you want a car that have to change capacitors every few years?

aiyo avia don so so many staff to deploy within 3 hrs. its fine if u only call when yr car is in the workshop, it is immediate in a sense.

 

u have plenty of time....and if it is only volt and earth cables, how long does it take to dismantle? within 20 mins or is it 5 mins?

 

my friends turbo only took 30 mins to dismantle.
