Hi, I'm a bit confused because can't figure out what kind of issue I'm facing now.
I hear a noise from the engine beetween 1k and 3k rpms but only with 50% or more of throttle and it's similar to a bad con rod bearing.
The engine is a complete fresh rebuilt (less than 2k kms on it).
It's a b16a2 with complete b16b drivetrain and b16b-spec pistons (runs on regular 97 pump gas).
I can tell you more: after my tuner set more advance with hondata the noise is increased a bit but he said there's no knock at all (tested during a recent trackday with appropriate knock sensor).

car runs really great and I'm really getting mad about it.

 

It was knocking because too advanced in specific rpms and throttle load. The tuner fixed it now is smooth
