Hi guys,
I am facing some issue here whereby I heard knocking sound from low RPM until 6500RPM. Which means when VTEC engage in 5800RPM, it still have abit of knocking sound but when it reach 6500RPM, there is no more knocking sound. (This is when I suddenly press the pedal when my car idle at 5th gear 100km/h).
But when press the fuel pedal slowly by slowly, there is not knocking sound.
Current my engine is running on BLUE E-Manage.
1. Is it normal for this setting? As dynograph shows 13.04 for Air/Fuel at 4500rpm onwards.
2. Knocking sound is not enough fuel. Is it?
3. Scare that not enough fuel will spoil my engine coz the knocking sound is evry obvious & loud.
4. Is my Works FPR faulty? Actually how to check whetehr the FPR is in working condition? By installing A/F meter or Oil Pressure meter?
5. Do I need to dyno/tune my engine again?
Hope someone sifu can enlighten me here.
