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
