maybe he was adjusting the ignition timing.
i guess ur car is auto tranny?:_:

 

[jimmy_WAI]

hahaha, dont tell me u expect alota horsie increase from changing plug ler.. not really the case ler.. the increase if any is too small, dont think our butt dyno is sensitive enough to even feel anything..

maybe can reduce some f.c?:_:
juz kidding.

 

[calvin9683]

nope...
mine is a manual...

 

[!!4g91!!]

nope...
mine is a manual...

30 bucks sure cheap than mine.. last week i go for MUT at 50 bucks..
I ask da pomen to adjust my timing during da a/c turn on coz little sluggish at low rpm.. Then ok.. FC quite good.. but some problem about my ECU.. Da igniton timing to low only 3-4 degree..
I think ur car got wiring prob coz both da rpm is same maa..
Mine is manual too..
Calvin..

[calvin9683]

[half_lif3]

4g91 carb does any1 know mech how 2 tune it??
cos my car jus did transplant n the carb got alot of wire haven attach
n he suggest me change 4g15 carb..
wat do u guys think...

 

[ayell]

half_lif3
Yup original 4G91 carb lots of wire, becoz it have its own electronic control. To use this carb we have to simplified it.. so, many wires will not be use. 4G15 carb can be use.

 

[half_lif3]

let's say if i wana remain my 4g91 ori carb
where could i found a tuner that tune 4 me?..or it is kenot tune according to my bawah pokok mech?
cos the carb now giving me prob tat kenot on air cond...rpm too high...etc etc...
if it can tune than i wont change to 4g15 carb

 

[ayell]

My mechanic here can tune the ori Carb.. but sometimes depends.. maybe the carb is not in good conditions that is why gave u problem. Btw.. where r u from?

 

[dareMAX]

Aiks... cannot be kua... I remember last time my 4G91 can whack city... no problem... even 1.7 civics also can whack no problem... =Þ

Then my car need to see doctor oledi.:regular_smile:

Anyone please advise,

Recommended change to 240cc injector or add FPR?, after minor mod. Which one better or they will serve different purpose. Please enlighten.

Thkz in advance.

Traffic Summon Charges in Malaysia

Price quoted below are nett without further discount, bargaining are subject to price increase without further notice.

Speeding: Exceeding 1 - 20km/h = $130 + 4 demerit points.
Exceeding 21 - 30km/h = $150 + 6 demerit points.

Exceeding 41 - 50km/h = $200 + 12 demerit points + Court.
Exceeding 51 - 60km/h = $200 + 18 demerit points + Court.
Exceeding 61km/h = $200 + 24 demerit points + Court.

If you want to be a hero and fight the court case yourself, and you lose, you pay the court charges yourself, which will add up to your fine. I guess the court charges is at least $200 and above.

Careless driving = $150 + 6 demerit Points.
Inconsiderate Driving = $170 + 9 Demerit Points + Court.
Dangerous Driving = $200 + 24 Demerit Points +! Court + Vehicle Compounded.

Do not hold your handphone in your hand when you drive even with loud speaker or ear piece.

Drink Driving (first offence.) = Up to $5000 Fine and, or Jail Term + License Suspended + Court.
2nd time offence = Jail term + Fine + Court.

Making an illegal U Turn when there's no U-Turn sign = $70 .

Fail to Signal when changing lanes = $70 .

Driving at night without headlights or taillights switch on after 7pm = $30 .

No Number Plate = $70.

Obstructed Number Plate = $70.

Obscured Number Plate = $70.

Number Plate Of Unapproved Type = $70 .< /FONT>


Demerit Point system :

Let's say you have 0 point on 1st January 2005, and you committed the offence of Failing to Put on Seat Belt.
So now, you will have 3 demerit points and this will last for 1 Year.

If during this 1 year you have no demerit points offence at all, your 3 demerit points will be gone on 1/1/2006.

But, if during this one year, From 1/1/2005- 1/1/2006, you committed another offence with demerit points, your very first offence will be extended for another year until 1/1/2007.

1.6 injector is a no no.. somebody have tried before using 1.6 injector and turns out burning mixture too lean, may lead to kaboom block.. Adj FPR is a wiser choice imho.. u can increase or reduce in marginal increament..

 

[ayell]

Guys.. fyi..
blow my tranny on Saturday nite sprint.. the effect of to much grip on the tarmac provide by fully slick tyre.. resulting me loosing to Satria 1.6 single cam

I'm using bigger inlet manifold + 60mm TB, now Air are too much. Bumper 2 bumper drive not so smooth, need to floor more a bit. Now oni pick up very satisfy, but after 140km climbs are bad.

4G91!!, dunno the 1.6 size. Saw many here selling GTi 240cc. Did you check your A/F ratio after change to 1.8 injector? Whats the reading before and after? I guess inlet manifold & TB size will also affect the AFR reading.:)

 

[bosz_77]
