i know i took the car to be tuned and the guy i guess just cant tune. the knock is really bad. i told him there shouldnt be any knock especially under wot. So i decided i would try and street tune my car atleast to get rid of knock and i can worry about power later. so i took the base map.... map injen cai and rh exhaust map and changed the injector size to 410 because im using rdx and then retarded cam angles back all over the board so that the wouldnt advance past 40 cuz 45 is max for these cams. i added fuel in a couple areas so that were a little lean. i have attached a couple short data logs and my latest calibration.......... tell me what you think i got rid of most of the knock and the car runs so much better sounds healthy and not having as many crossover issues.

Looks like you have too much cam angle advance for the blueprint stage 2 cams. I see it all the time, you don't have the free flowing exhaust for it. Drop the cam angle up top and watch your power rise.

from where to where and by how much would you guess. also is there a way to make the car stay in vtec more like when im letting off the throttle some and shift the car rpms are still in vtec but it disengages is the a way to keep it in vtec so the transitions are smoother
