dear all sifus,
Just wana ask for opinion. Currently using Mivec 4G93, PnP, racing clutch, adjustable cam pully, light weight crank pully, adjustable fuel regulator,Simota open pod, original mivec piston, 390cc injector with Emanage inside.
Done dyno few weeks ago, but some how i still not statisfied and confident to rev my engine. As the tuner said my engine compression is too high (around 14 compression ratio) that cause the knocking noise. At certain rpm my engine will creates knocking noise and i don even dare to accelerate more. But, the tuner told me that my A/F ratio is good (11-12++) and the noise cause by my high comp piston.
Do i need to remove the ori mivec piston and install the 4G92 piston or i'l just drive like tat as the tuner told me just the noise and would not cause any damage to my engine? Is that true that wont cause damage to my engine?
