Dear all,

just want to get your advise.

my car already done some mod, there are:-
1) open pod Simota air filter
2) double layer of break pump
3) normal brand spark plug cable
4) add E-Power (voltage stabilization) for spark plug
5) side gapped oem spark plug
6) add similiar product as micro compressor
7) add 2 pcs of cyclone
8) 4-2-1, middle box and S-flow muffler
9) CAI hose

So isn't my car need to do tuning or others adjustment?

Remark: my car is Proton Wira 1.5 EFI Year 2005.

dun need tuning... svdo ecu will auto recalibrate because it is a self-learning ecu... it will adapt to the changes made and adapt to ur driving style...

aik..like tat also can.. so is ok that my fren ride stick to 160??scare that the engine is already damage and if u repair..is like those 3rd stage cancer..cannot be repair.. and my fren dun mind sticking to 160 all the time..just that he scare that there is some internal damage that we cannot see or feel..

save the money and remain 160km/h ler
Its good enough, tell your friend, cherish his life more, and save the money

Recession nowadays, save money

Dear all,

just want to get your advise.

my car already done some mod, there are:-

1) open pod cap ayam air filter
2) grounding cable
3) zmax volt stab
4) add similiar product as micro compressor
5) 4-1 header, stock middle box and S-flow muffler

So isn't my car need to do tuning or others adjustment?

Remark: my car is normal campro persona 1st gen (no iafm no cps)

dun need tuning... campro also uses siemens vdo... also self-learning ecu... will auto calibrate itself according to changes u've done to suit ur driving style....

btw, microcompressor is useless.... especially when u have a self-learning ecu such as svdo.....

Hi Something DIY.....perhaps can remove the Open POD Air Filter pipe and the filter, at the throttle body there terus use cable tie to tie the HKS filter form only......

tried on my wira 1.5, better kick then piping Open POD filter.....

can give a try

of coz mah.... high revs will be damn syok.... but low rpm low speed suffer lor...

the theory still applies.... its all about flow efficiency... not alwiz da case bigger is better...

Bro, i have the same problems with you.
Same wira 1.5 GLI.

No power at all and petrol consuming.
City drive, slow drive. 40litle can go 400 km\h only.

Pick up is suck, felt the car very heavy, hand brake release or not releae as the same.

Open port and drop in have huge different?
After mod this air filter will more fuel consuming?

Pls advice

moding for sure will drain more fuel ...

i think of people here who mod open pod neglect the fact that it needs heat shield

i advice use drop-in air filter.... better flow air filter suppose to increase performance and reduce fc abit.... because it has higher airflow and do not clog up so easily.... hence u get good amount of airflow, which helps ur engine breathe...

but one thing to remember, prevent it from sucking hot air around ur engine bay excessively... datz why i recommend drop in air filter for beginners because it is plug and play, no hassle...

if u insist in using open port, make sure u make a functionable heatshield and cold air intake for it...

not necessary... i previously using open port, gained better fc....

agree

Normally for p.wira 2004 1.5GLI can up for how fast?
40litle can go for how many KM?

I have change the center box and muffler.
But i found that the car still very heavy.

I will change 13" rim to 15" next weeks.
See can more heavy or not

Normally wira increase performance and save flue is change center box and muffler. right?
Branded air filter like KNN, HKS and Apexi's is get big different compare with which common brand?

Low power car like my wira will take effect if i installed open port air filter?

what makes u think changing centerbox and muffler will make the car lighter
changing to 15" will futher kill ur FC

ur car manual or auto tranny??...

i've seen wira 1.5 habis meter (180kmh) before....

normal drive, 40L can average 4xx km on ur tripmeter..... of coz dats depend on ur driving style...

if u wanna increase performance, dont think about saving fuel so much.... if u wanna save fuel, dont start modding ur car... besides, we must also see what kinda modification u do to ur car... for example, exhaust pipe, not necessary the bigger the better....

i would strongly suggest u to use "branded" air filters such as K&N (not KNN) or apexi... at least the performance gain is assured.... i've heard enough terrifying stories people using cheapskate filters that broke down or being sucked into the engine....

low power engine also can modify... not necessary must be nice car only can modify.... modifying scene has no car types barrier....

depends what kinda 15" rim he use lor...

even he use the lightweight rim, that doesnt defeat the fact that the rim is wider and bigger.. u still ned to overcome friction so that the car moves

one more...this will usually solve ur problem...

how much extra rolling friction he will need to overcome if he upgrade from 175 tyres to 195 tyres??...

well, u tell me, my math sux lolz..
anyway, previously using 185/15.. after the tyre end its life, i changed to 195/15.. can feel the drag definitely
whats more 13" if ori proton is using 165/13 and whether if he can afford a true blue lightweight rim is still a question

u mentioned about da disadvantage mah... u explain more about it lor....

how come i switch from 195 to 185 cannot feel any difference??...

is ur 185 and 195 similar tyre model??...
