2011 Accent AT - Engine Knock!

[andretti]

aw pala bro kapag pinareset yung ecu natin kung wala naman tayong engine knocking sounds

yun nga sir...
matawagan nga muna casa bago dalhin unit ko dun, either way may 2months pa naman ako bago ko pa 5k PMS.

[mexophilia]

Ok guys, nababalitaan ko nga dito na maraming nagpa-upgrade o update ng ECU tapos humina ang hatak. Ganito rin ang nangyari sakin. After the update ng hapon pag kuha ko humina ang hatak at aircon.

Question po muna mga sirs na-try nyo na ba na mag ECO setting. Napansin ko nakapag ECO setting mahina ng konti ang hatak at aircon. Ganito ang feel ng na-update na ECU, parang naka ECO setting. So feeling ko hininaan ng Korea ang power ng kotse para di sya mag engine knock.

Ang naging solution ng Hyundai sakin dahil sa pag-aaway namin ay replce na ng ECU. After the replace ng ECU gumanda ulit ang takbo ng kotse mga Sirs. Di maganda ang solution na ginawa ng Korea para sa engine knock. Mga hayop ang mga yan at niloloko tayong mga consumers.

Don't let your ECUs be updated magsisisi kayo. This is not a solution sa knocking hininaan nya ang pasok ng fuel sa engine at gradual nya ito pinahahatak.

Problem: Updated ECUs cannot be downgraded to the old software. Replacement lang ng ECU ang solution para bumalik ang dating takbo. I had mine replaced, hope you guys get yours.

Alam nyo ba na nung nireklamo ko ito sa HARI, sinisi pa ng gagong HARI ang driving ko at kesyo para matahimik lang daw ang customer pumayag sila sa replace ng ECU. Na-confirm ng Service adviser ko at ng mechanic sa Casa na wala ngang hatak.

Anyway, goodluck sa inyo sa pagpapareplace ng ECU. Iwas nalang ako sa Petron kesa parang pagong ang takbo.

[Starex_Gold]

May bago na naman tayong problema hahhahaha ano ba yan, walang katapusan. Di ko napansin yung sa aircon na humina, pero definetely yung second gear ko naging slow ang response.

Hehehe. Try mo ihataw ng ihataw para mag-iba ang behavior ng ECU.

Ganyan ang ECU sa umpisa kapag bagong reset, aaralin muna ang driving habit ng driver.

[mexophilia]

Mga Sirs,

Sorry nalang po for butting-in pero miski na anong hataw mo di sya babalik sa dating takbo. Yung learning ng ECU ay laging ayon sa particular setting, may range sya of responding to every driver. Kumbaga may 1 to 10 na pwedeng aralin ni ECU, pero what they did sa ECU update ay nag define na ang 1=-5 and to 10=5 miski na aralin na ni ECU na hataw ang drive mo kung ang 1 to 10 mo ay defined lower ganyan na ang takbo nya.

2 weeks na ganito ang kotse ko at enough na yan na learning for an ECU nag spend pa ako ng 2 full tanks. Pangit parin.

Research also the internet for problems with power kapag may mga ECU updates. Wag lang tayo basta maniwala miski sa mga mechaniko. Maloloko kayo. Always feel how the vehicle responds.

[jayvel]

mexophilia, saan dealer ka nagpapalit ng ECU? so ibig sabihin pinalitan sya ng Bagong ECU na original settings pero prone pa rin sa engine knock sound kung magkakamali ka ng pagpakarga ng fuel? Di ko masyado napansin yung sa paghina ng aircon, pero yung sa second gear ramdam talaga. Pag binalik ko to sa Casa ano kaya mangyayari? Siguro dapat ito madami tayo magreklamo para strength in numbers, Tama si mexo baka paikutin tayo ng mga SA and mekaniko, What do you think guys?

[callmenadz]

Hehehe. Try mo ihataw ng ihataw para mag-iba ang behavior ng ECU.

nun una ganito ginagawa ko sa car ko hinataw ko nang hinataw tapos ngaun naka fully synthetic ako hinahataw ko pa din nang saka nang daddy ko kaya siguro wala akong engine knocking?

update ko lang po kayo sa accent ko nag punta kame sa manila from nueva ecija talagang sagad na sagad nun papunta kase nag hahabol sa oras yung second gear umaabot na ata sa 90-100km kapag nag oovertake tapos yung tersera till 120 then nun nasa sctex and nlex na 140-145 km lang takbo sabi ko bakit ayaw pa isagad masyado pa daw bata yung makita. hehe my FC is 8.4L/100 km sulet na sulet nanaman si accent nun nag byahe sa manila very satisfied din daddy ko sa performance nya ang liit liit daw nang makita kalakas umarangkada.

ang ibig ko lang sabihin try nyo i sagad yung accent nyo baka mawala yung engine knocking na yan baka may nagbara lang na tinga tinga sa engine hehe

share lang po.

edi ibig sabihin kung bago ECU mo does it mean na di na mag knoknocking sound yung accent mo? kung ganito dapat mag pa replace lahat nang accent nang ECU sa mga dealers nila para mawala yung engine knock.

NO, it doesn't mean na di na mag kno-knocking ang engine mo. It was replaced with a new ECU with an old setting (kse nga di na mai-dodowngrade ang updated ECU). I would just veer away from Petron products kesa mag suffer ang performance.

Go back kung saan nyo nakuha ang unit and demand na i-balik ang dating performance, syempre e-enter frame ang HARI. Be firm na ipabalik ang dating performance, ang HARI pa naman ayaw na ayaw mag replace ng mga parts. Eto pa ang catch, magtatanga-tangahan ang mga yan at sasabihin na wala namang problema ang kotse. Well, wala nga mahina lang ang acceleration, stupid mother^#*#*^**$rs! Nakakainit ng ulo ang mga taga HARI. At sabihin nyo na din na may mga naayos ang performance sa pagpapalit ng ECU, kamo na solve ang mahinang hatak.


Pray for it guys, we need God's help sa mga taong ganito.


Hope this helps.

[spyler]

Nag pplan pa naman ako kumuha ng accent. Parang hindi na ako kukuha ng accent siguro. Nakaka temp kasi yung price. hehe parang mas mahal pa AT na kia picanto sa accent. Pero mas malaki ang accent. Kaya lang habang nag babasa ako dito. Parang nakakatakot na kumuha. Baka mang yari din sa akin knocking issue, door lock problem, bottoming issue ng shocks sa likod. Maarte pa naman ako. Sympre brand new tapos ganun. sana maayos na nila ito para mas dumami bibili ng product nila. baka kasi maubos din bibili ng accent pag ganyan problem.

ic siguro yung mga unit nang accent ngaun na ipadadala nang hari naka update na yung ecu? di naman kase mapapansin nang mga bagong owner yon. kasi di nila alam kung paano humatak yung accent. anyway i hope wala nang knocking yung engine mo in future. update mo na lang kame dito hehe salamat bro for your responds!

walang perfect car bro! isa lang naman talaga ang main issue nang accent which's is the knocking engine yung bottoming issue nang shock lahat nang accent ganon talagang naka design sila nang ganon. gusto lang nang iba na mawala yoon parang fortuner lang na matagtag yan :D

[maxhedrum]

I don't get the fuss with the performance. The car is 588K!! Look at the the alternatives for a 588K car:

1.1 i10
1.0-1.2 Spark
1.0 Picanto
1.1 Celerio

what you get:

Less trunk space, less legroom, cramped backseats, less powerful engine

If you're single, the above shouldn't bother you otherwise its a no brainer. If you have 300k more, knock yourself out with the other cars brands or buy a TOTL elantra. I'm sure 1.8/2.0 should be enough when buying groceries.

No offense meant guys.

+1 ako dito.

I am into motocross and somewhat keen into suspension settings. Ang problema ng suspension ng bagong accent is its compression & rebound ratio. I think it was tuned na the suspension rebound play is the same as when it compresses. Kaya ang nangyayari nyan, talagang maalon. Unlike other cars esp. euro ones, na iba yong rebound ratio ng suspension, medyo mahina and very calculated yong pag angat.

With spring cushions, you changed the compression ratio, but not the rebound ratio of the suspension. Kaya ang effect no'n, is para kang naka left spring.

I think Sonata has its "Active Geometry Control Suspension" if I am not mistaken, very controlled & calculated yong compression & rebound ratio, and the computer calculates what's the best ratio on a given road.

[mexophilia]

The topic I believe is 2010 Accent AT and this costs 688k (worth 100k more) right.

I also believe at that price range you wouldn't consider a picanto or anything less, you would consider a Vios or a City.

People who buy the lower model cars either loves em or has unfortunately lesser money, which is never a bad thing. We bought the 2011 Accent because it performs like an Accent and not like a Picanto.

If Hyundai didn't gave us this kind of power from day 1 we wouldn't make a fuzz. And also, if this Accent performed like this during test drive I wouldn't buy one and I certainly am sure that a lot of you out there won't too. If you're given a 10 and after an ECU update now performs a 5 then its an issue. Telling consumers na okay ka parin kesa sa picanto or ano pa mang lower models is a Sales Agent's line (forgive me but its totally stupid). In the first place this is the reason mo kaya mo sya binili. It has good looks and good power and according to Top Gear Philippines, it out shines the Honda City. Pero after that ECU ****-up you have a 50% reason to buy one.

Balikan nyo ang mga Dealers nyo, request for what really is yours. Sakit ng ulo yan, time na pasakitin nyo naman and kanila.

Are we the only country experiencing this problems with the knocking issue with the 1.4 MT and AT?
It would be a basis if its really the the fuel or the engine.

Been searching sa net pero ala naman...
Sa India nga may 1.4 and 1.6 diesel pa ng new Accent!!!

So far pinas pa lang ang may ganitong problema. Hinahanap-hanap ko nga din if it has similar issue on other regions. The middle east has the same engine specs as ours.

US gets the GDi version in w/c we really can't compare...

Probably main culprit is the Fuel quality. An ECU reflash would probably ease the issue. Just wait for ample time for them to find the perfect ECU settings. Ngayon kasi, I think Trial & Error pa rin ang solution na ibinibigay nila in which I find it very disturbing. Buti na lang 'coz I never experienced those knocking sound.

[callmenadz]

edi meaning sa fuel nga talaga natin to if ganon?

added: *miekey and andretti saan ka nag kakarga nang fuel mo?

ako kase sa caltex lang and always gold lang.

Is there any doubt about the fuel quality here?

(note: 1.8 liter Revo. This is one of the reasons the Revo 2.0 is such a gas-guzzler... to prevent "knock", they tuned it to drink like an Expedition!)

There are even more horror stories on other boards. On the Nissan and Ford boards where I'm a regular member, some people also experience "knock" on new cars on certain gasolines from certain stations on their Sentras and Focuses. At autoindustriya, there are members with OBDII readers who notice knock count get higher on certain gasolines, despite those gasoline being advertised as higher octane than certain others.

The advice is always the same... change stations, change gasoline type. It's especially questionable if the fuel has a lot of ethanol additive whether the advertised octane is correct.

My recommendation, if you don't want to muck around with reflashes:

1. Drain your tank. Fill up with V-Power at a trustworthy station. The 96 and 97 RON gasolines of other makers really aren't the same as this gas. Blaze is even better, but some performance car owners actually don't like Blaze because quality differs from station to station. Observe. If no knocking, your car is normal. If it knocks, then there's a problem and your particular unit needs a reflash.

2. Start going down, go from there to Shell Premium... then down to Unleaded. Pick the cheapest gasoline that doesn't cause knocking. It will likely bet 93-95... and even then, the 93s might not work in hotter weather if the alcohol content evaporates or goes stale... so it may be worth mixing it with V-Power or Blaze (the benefit of blaze is it doesn't rely on ethanol for RON numbers).

Simple. Easy to do. And it will tell you if the problem is really with your car or with your local stations.
