just got the unit after it was checked up by hyundai greenhills, according to the SA they didn't reset or updated the ECU coz no need for that daw base from the result from the ECU they just "refreshed" it according to him

. pero so far wala pa naman ako na rrining na knock even at low speed.
Just curious though, hope our car experts can provide some info on these questions:
1. If there's really an enging knock issue should it be present most of the time normal speed specially on an idle engine and not only at low speed?
2. if it's only at low speed could it be more of a gear shifting concern specially with AT transmission where it's controlled by a computer? from what i experienced kse the sound is more of "parang hirap ung makina" at low speed specially if you're "babying" the accelerator but if i'll just normally step on the gas no knock sound at all.
Hope someone could clarify if this is really an engine knock issue or something else. Thanks!
