Extremely sluggish low-end

[Ken4555]

Not tat exactly true bro. Modern ECU do have the ability to adjust air/fuel ratio but only to a certain extent. Tats where piggybacks come in. One good thing of piggyback is they got a whole lotta things u can tune. Even ur car is stock then u put piggyback, ur car wil feel more responsive definitely cos stock ECU setting normally run rich.

 

PS, my car dun have any piggyback but if got the cash, definitely in the list to do....

 

yes agreed bro... but most saloon cars after tuning gains are minimal... spend so much and worst is if tune out of tune... actually i would love to drive a well tuned car... but if the car stock without mods than ecu should stock for longer life span of the car......

 

cheers

The fact that you're on stock setup denotes why u have sluggish low end ...most cars nowadays have a reservoir for low end. A good well designed intake will have direct intake from front of the car that leads DIRECTLY from front of car usually near the bonnet for direct and straight flow to the airbox. Most Ja n Korean engine designs do not have this luxury so they create a reservoir for the airbox because they cannot give a direct intake due to their crappy engine bay layout. The only car that I've seen so far that has this intake is the VW Golf MK V / VI

 

My 2cents worth...........

 

well my 1998 jap designed car has a stock direct intake from the front. I think nowadays, almost every car comes stock with that, not only conti makes.

Agreed man. If get good tuner, u r safe. If out of tune, it wil do more damage than gains! Tats y for me, i prefer dyno rather than road tune.

[Ken4555]

i heard better to dyno tune then road tune...

 

cant wait for changi track to open... i can imagine our local workshops getting a location there... in a race track...

 

saturday nights will never be the same again....

And so are you? ....You will never be the same again....

Imo, most bread and butter cars are built for..... well, reliability.

That's means no "CAI", but convoluted twist of air intake pipes for safety, in case of flood.

 

By doing a simple straight pipe to the front of the car, your engine response will improve quite a bit without needing to go for ecu tuning. Of coz, tuning is much better, but at a higher cost.

 

Most stock car are tuned on the safe side for reliability.

 

However with CAI, your airbox will also tend to collect more gifts, like dirt, sand, leaves, insects, etc.

 

As for the resonator box, some people mistook it for air "reservoir".

That's not true, it's purpose to trap noise from the engine and make the car quieter and feel more "luxurious".

 

To the manufacturer, you can't sell a noisy car with low reliability.

Thus it is what it is.

And so are you? ....You will never be the same again....

 

i same lah... maybe my car wont be the same...

[Ooosh]

bro....hyundai and kia cars have a reputation of overstating their HP....unless dyno proven by yrself...

 

remove your CAI no point if your not running turbo use a closed box open pod then get a reputable tuner to tune your car ECU to lean out the air mixture to give more pulling power on the low end.

 

Any changes to the air intake the ECU needs to be tuned....yes it might adjust to your new settings but it is only conservative....

 

In this way you will enjoy yr ride more....

is this the stock avante engine bay??

 

[XenonWhite]

is this the stock avante engine bay??

 

Dun seems to be an Avante engine bay, might be a forte..

[Versatile]

is this the stock avante engine bay??

 

That's a X20 engine bay.

 

X20 is 2L Avante in malaysia. I believe the engine bay layout is the same as the 2L in SG.

I've seen i30 peaking 140PS @ 4200RPM with CAI, Unichip and decat.

I think the main culprit is your bigger rims.

 

If u fitted 17" from 15", & u didnt lower your tire profile, your tire diameter has increased which wil give u similar situation as a higher gearing.

 

This wil give u less power but u wil also get a lower RPM for same speed travelled.

 

I also upgraded my 14" to 16" rims but fitted a lower profile tire so my total diameter remained about the same & I didnt experience any loss in power.

 

Maybe u sud check the sites which advise what size tire u sud now b using with your bigger rims & change tires asap. U sud then get the same power as b4.

power....if onli the avante can do tis...

[Beehive3783]

power....if onli the avante can do tis...

Why not? The Avante and i30 share the same engine leh..

[N3ver]

whoops...i forgotten

[Alechi]

by pure mechanics ... your 17" can potentially cause an amplified reduction in rotational force of 15% and beyond (depends on resulting tyre thickness as well)

ur other "customisations" as listed don't seem capable of compensating the rim size change.

 

other extras that bring you back to comfort level will cause your FC to be darnn crappy ... better think again friend

 

 

I've been experiencing sluggish low-end especially during 2nd gear after i change my stock 15" to 17" recently. i've changed k&n drop-in filter & customize cai. the problem could be due to the 17".. and yes, i'm on lenso samurai sc01 (it's considered as the "lightweight" cat w/ 7kg per rim.)

 

was wondering what can be the next steps to improve my low-end? i've no issue with mid/high-end and can feel the power with anything above 5k rpm.

 

i'm looking for parts that don't void warranty.. please advise if any of the below that helps and feel free to suggest if i do missed out any.

 

- change stock sparks plug

- change stock sparks plug cable

- pro steel RS brake hose kit to improve stock brake kit

- lta-approved exo (sadly, in the market current don't have any)

- uniQ piggyback

 

yes, i'm driving avante 1.6MT.

 

thanks.

If your overall circumference of your current tyre and stock is different, do you think warranty still effective?
