TQ Z1 for the confirmation. However, I have more finding in 1 day, may be more than erictioh himself. Here we go for the detail:

Initially, after magician charged the VS from a static charger, we saw its already stable at 13.9V, so I disconnect it, bring it over to the car. As I walked towards my car, I figured the LED started to dim. Until I fully loosen the terminal, reconnect the VS, I figured it started to discharge drastically. Magician use a test meter to load the VS, left 11.8 volt. Magician was dulan, ripped off the VS & found inside lined up with rolls after rolls of capacitor. We found the voltage was 16V. So magician quickly came to a conclusion, reason for 16V is bcoz our car charging at 14.5V optimal, terefore a 12V capacitor could overheat very quickly, that's why eric ue 16V instead. However, the downside will be current quickly get discharged if not fully charged at 16V. That 1 hour when I was posting my previous post has gone down to drain, waste of time to dry run the capacitors.

2nd round, we disconnect the wires from the terminal, left the terminal attached at the battery, we took the entire battery + terminal hooked up with the VS,charge the entire battery+VS at the sametime for 2 hours! After that, we disconnect static charger. This time we tested reading stays at 13.2V for more than 10seconds togather with the battery!!! "Dry run in" success!!! We hook back up the whole battery + VS, everything is in order. We start the engine as usual.

Result was slightly better than my usual drive. I hit the pedal, there's significant improved on throttle lag response. I can see some different this time despite the VS was in the car for long time previously. Call it placebo, but it does show some difference. I do not have ECU "NUT" tunning in my car, so any improvement on engine response can be felt immediately. Pedal response is immediate. I hit the road for a long test drive whole afternoon until now, reach Kemuning, waiting for Nazri in the car typing this message. Overall, erictioh VS is very useable after a PROPER run in. Believe it or not, I've been using the VS since August, I have never felt the effect until today - get to fully charge the damn thing with a static charger!!! If compare it with the expansive VS my poison master sg999 is using, I believe its nothing to compare. Erictioh VS still lose half a kilometer. The initial acceleration has been improved, but the pedal lifting response still lag. I believe it improved a little bit, but when I drag from 1,2,3,4th gear, the lifting response still can be seen. For example, 1st gear WOT, the car went BEM.......6.5krpm,declutch,lift gas pedal,RPM suddenly jumped to 6.8krpm whilst I'm engaging 2nd gear.

Magician got a theory, but wasn't able to prove it. However, I'd like to share it here for speculation. The reason for my VS not fully functional despite its been running in my car for 3 months, its because our alternator voltage was not static. Before the medium/large capacitor being fully charged, aircon kicks in & draw power off from the small caps. Everytime we off engine, voltage drops back to 12V, and that is not running the VS afterall. Do remember we found out those capacitors was 16V. In order to have optimal charging, it needs 16V, so 14V charging could take much-much more longer time to "run in" the capacitors, may be years. So, we guess it could be the case that when the capacitors are fully charged, the driver already got used to it and forgotten the goodness of having VS assistance. We believe erictioh couldn't use anything lower than 16V otherwise the VS reliability will become questionable.

Lastly, we conclude that everytime we disconnect the VS, it needed another full run in before we can feel the effect of a fully functional voltage stabilizer.

yes that ass!
Damn I copied my videos I forgot to bring home the harddisk. No movies to watch for 2 nights.
sure ask ppl buy.. haha


got my case but dunno can fit or not. -.-

Not so nice compare to first one...

can i say we charge the VS by starting the battery, but not the engine? i mean 1st click of the key, but not ignition.

and i'm very curious sg9999's vs is from which seller or brand?

mar say from kuching lor..sarawak so big ler..he sell berapa ribu? best comes with uF details.

I was thinking why the VS was able to improve throttle response, then I remember V12k last time ter-pasang the Firestorm onto his ECU and got WTFBBQ throttle response.

Maybe it has something to do with stable / improved voltage supply to the ECU?

The 16V means the highest voltage you can apply to the capacitor, in engineering term, this is just point of safety limit. Larger voltage limit with same capacitance will result in larger physical size, which often limits our design. Not so sure how it affects discharging practically.

I have a suggestion, we can buy those battery chargers that are intended to be plugged in for long term to our car like this: http://forum.lowyat.net/topic/1169104/all

Few points i would like to share here.

1. Capacitor run in is a myth, until today. This run in term often used in audiophile, and argueable forewer.

2. The capacitor rated voltage is voltage it can withstand and store before the cap damge. So for a cap with rated 16v and 25v, if both are charged to same voltage, the discharge time will exactly the same, no such thing that if the cap is charged lower than its rated voltage it will discharge quickly.

3. Depends on the R fo LED, LED will drain around 5mA, so when u disconnect from charger, the volltage drop is normal as the charge is drained by LED.

4. i disagree 25v need more time to "run in" compare to 16v cap if charged by same voltage.. Cap will degrade over time, especially inside the engine with high heat, it will accelerate eletrolic dried up inside the cap, thats why solid cap AKA condenser is used by those pivot or whatever well known brand, a year to run in an eletrolytic cap? i will say it performance will reduce rather than 'fully run in and perform better".

5. Again, a cap that always charged near to its rated maximum voltage will degrade faster than charge lower from that. So if i'm going to DIY, at least 25v cap will be used. Our alternator when running is around 14.4, cold start @ 14.8v, is way too near to the 16v limit. DC multimeter can only show average voltage, so the reading is stable, If using osciloscope, u will not surprise if you find the spike with higher voltage than that.

6. Capacitance will increase in high temp, as high as +20% from the rated capacitance. So it is not surprise if the performance after u purposely charge or after long run is differ than cold start.

7. The reason why higher voltage (25v) is not used in commercial product is mainly due to more expensive and size is larger, accomodate for the cap require larger casing, so further increase the cost.

VS does prolong the battery life time. When our car is running, VS keep charge from alternator, after we switch off the engine, the charge from VS is kept and discharge to battery or self discharge overtime. After that when we restart engine, starter will draw very high current. This is why CCA (cold cranking ampere) is important. Now VS especially those with larger capacitance will play a role. The current draw by starter will draw simultaneouly from cap and battery, so it helps to reduce load from battery.

My car now 3 years 2 months still with stock RAMCAR battery, i think VS help abit.

Thanks for the info. I have little knowledge in electronic engineering
I do not disagree with you as I have no prove to all that. The only thing I know is, this morning the engine response was not there despite its in my engine bay for 3 months. It happened AFTER the VS being charged for 2 hours with the battery itself. It could be the battery, not the VS. But so far I'm amazed and surprised by the performance I have, despite its incomparable with the f***er who poisoned me. Anyway, I see some lights now and will move forward. I'll be taking out the possibility of getting the RM860 VS. I'll move forward with a sound grounding kit and the huge ass welding cable as soon as I hold some solid info

Btw, thanks for spend time educating me. Learnt alot from your post. May be I should go and buy a 250V 1.5Farad cap and plonk it inside my boot

To be honest, i really thought before to buy those audio used cap and used as VS. That one is way better than i DIY a large capacitor bank. The reason why i still yet to DIY is becos i can't find a proper way to accomodate the capacitor bank.

Anyway, those grouding cable is just noticeable for old car, as the old cable conductivity is reduce and fatigue, for new car the effect might negligible. If you reach enough, change all the cables to huge ass welding cable will see the effect.

The uf is just a information to make you believe on it is powerful. But different manufacture have different quality, like why ppl like to buy S3/iphone compare to China branded fake phone. The diy seller is actually imported all the capacitor from out of Malaysia. Not pasar road quality, so uf is not suitable to decide the product potential.

I dunno how is the big one and i bought a long one.. -.- 

bro r3apers.. itu cabin light hah.. will it get spoilt easily ar? coz last time i rmb i installed those that comes with 12 bijik led one.. easily spoilt because i always leave it in on whenever the door is open..

so ini jugak ini macam kah? or do i have to on it whenever i needed aje?

dunno..

this week almost fully booked jor... pasang firestorm. lolz

this wan big lo.... u bought the 10 or 15 bucks wan?
will be much better thn those LED wan...at least worst come to worst also can be more than a year.... lol ^^
cheh... let me know a day or two early whn u plan to go visit...

for u it might be just marketing gimmick, but i did consulted my DIY fren for my VS, he told me few stuff about that uF thing. so believe it or not, uF seriously will affect a VS's performance, let it be very high or very low. what we require is a balanced and optimized uF.

sg999
seriously speaking, the +ve technically is an upgrade as well? im quite curious with the GC ur friend produced. the 5 cables are evetually having the diameter, but after the connector, the single cable attached to the -ve seems to have the same diameter like the other 5...isnt that not relevant enough? it is like a 5 lane highway merging into a single lane lorong...the discharge might be reduced, no?

Getting my armrest for tomorrow, so happy

On a side note, am thinking of getting a pair of foglamp for Bebop. To anyone who added foglamps, where to put the switch for foglamp?

+ve is for better charging of ur battery. U will feel ur engine heavy when alternator keep on working, the stock wire it does charging to battery but high resistance, adding this is to reduce the resistance so the charging process can be improved. However, if u put 9999999999999999999A big think cable to charge ur battery, it still a resistance there.
For gc issue, do u think this one is better if based on ur theory?

this is big meh? long only wor... this is only RM5
