If hyundai can not upgrade my ecu anymore, will there be any other remedy? To be honest i'm getting quite disappointed with accent.. Even the fuel consumption.. Sobrang lakas pala sa gas... I'm just getting 7km/L.. Pag traffic 6km/L pa..

You know what? I think what you're describing is my accent, same intermittent delay when sifting from first to second and that loud thud when the second gear kicks in. We even have the same fuel consumption. So cheers, the problems you posted are common among accent a/t's

has anyone tried to change to colder spark plugs?

same with my M/T after euro2 update, even higher (9-12 km/L). supprised with AccentHyu2012 and sir Bratski's (even after euro2 update) fuel consumptions. seems euro2 works better for M/T, hoping it's for long term.

AccentHyu2012, I suggest you have your ECU updated to Euro2. Huwag yung Euro1 - Euro2, medyo sasablay as per the postings here (back read lang). kung nabasa mo lang lahat ng post ni sir bratski...

I'm actually not surprised with my fuel consumption, considering its a/t and my daily route (which happens to be bumper to bumper), practically no highways, average speed according to the computer is only 11kph.

Hello Guys Im planning to get a BNEW 2012 kia rio but upon testing my chosen unit I heard like a typewriter noise in the engine at idle. took a video and uploaded to youtube.
Is this the same sound as the Accent Engine knock?
thanks

Pag malamig pa ang makina may kunting lagitik talga yan, even my 1.8GLS elantra. after few minutes swabe na, tahimik na ang andar.

I hope this helps. :toast: My sister's 2011 1.4L Accent A/T issues were recently solved by a complete replacement of the CVVT system by HARI. She also went through the whole charade of ECU software updates, advice of only using only Shell 97 octane gas, etc... with still the presence of engine knocks, high rpm upshifts, poor engine performance and poor fuel economy. :ill:

With the 2013 1.4 6-speed Accent, kelangan din +95RON or pwede nang lower octane? Pasensya napo page 27 palang ako sa thread nato. lol pero balak ko talagang basahin lahat. :p
