My car with VS

[Mikhai]

I just installed a VS into my car. The first day try out was very good. The things I've noticed are,

1) Car becomes smooth at constant speed.
2) Acceleration smooth but no power gain.
3) Conclusion: Car become smooth, but no power gain, no brighter head lamp or colder air-con.

Overall feeling is satisfactory, but the next day.... everything back to the same...

1) At constant speed, my car chokes when air-con condenser is on.
2) My car choke and slow for a short moment during acceleration when air-con condenser is on.
3) My car choke and and shake (like go front and back) at slow rpm (~1.5k) when air-con condenser is on.

Car model: Wira 1.5 a[ecial edition, manual, year 2004.

Can any sifu explain for me please? Also what are the recommendations? Thanks.

whats a vs?

 

[nitrus]

did u diy ur VS or shop did for u?

u sure its done correctly?

if everything is correct, maybe it's all juz in ur head... u noe la.. butt dyno ... hehehh tats why i never like put any real attention in "wat i feel" after i mod something...

 

[Mikhai]

Voltage stabilizer.

I bought it. Isn't it just connet the black to -ve and red to +ve? It is not just feel coz the choke is very obvious.

Somtimes, it might be just a psychological thing....but i might be wrong

Some time back...I installed a AMAF.... After installing it....I feeling that the AF was bit better but not sure if it was just my imagination.....so after a while of driving.... I look see look see... and have an idea... so I decide to DIY the AF to be mushroom style.... but square one.... then I give it a drive.... and first thing I know is that the sound is louder with bassy kind of sound.... then I test drive a bit and can feeling the difference in pick up power.

Air filter blocked liao.... Not the big square one, but before to injector part where the rubber hose joints the metal part.

Air filter block!?!?

 

[K_Takuya]

in other words.. ur combustion may not be done properly.. check ur injectors, spark plugs, spark plug cable and air filter..

For a wira injection, the most common problem is this, anyway does your car engine just stop suddenly when idle? If yes, then is that part blocked.

banyaknyer "feeling" ...

mikhai ... think u shud just check properly whether everything is right, or not ...

if it is all right, then its juz in ur head... VS / grounding cables dun reli do anything much, especially on new cars, like urs 2004 model .. quite new. .. dun expect like great acceleration or watever from these voltage-related things... juz sit back, n relaxx...

 

[fritz]

yeah..vs doenst really work much for new cars..

 

[yyap2]

i drive wira special edition too... but when de air con condenser kick in... i wun feel much of lack power then b4... b4 i dun have VS on it.. lik when de condenser kick in.. i can feel all of suddenly de car loses power then i was in constant speed.... wat VS u brought.... I plainin to do grounding soon

 

[Mikhai]

Hi yyap2, I bought the Zaptor vs. All my other friends Wira SE don't have this problem, only mine... I really think that is ECU problem also. Last time, my car shake very bad in the morning, mechanic also can't fix it. But after about 3-4 months, back to normal... I'm so sad about my car...

 

[kyheng]

Did they adjust your timing or not?

 

[yyap2]

mikhai u drive manual or auto... last time my gear kong le... auto... when i accel de car shake..
only in 1st n 2nd gear..

i am driving N13 year 1988...before this experienced the same problem...when air con kick in...choke...lost power...
but after i install GK+VS from C-Ground(DIY)...now feel better...smoother in acceleration...but no power gain lar...then air con kick wont be that obvious anymore...overall is satisfied with it lar...mayb need some tuning for the air-cin idling?
