Knocking below 4k rpm and under 35% throttle

[saechao04]

Hey guys finally logging with ecmlink and I am noticing a lot of knock. 3k miles on fresh rebuild with wiseco pistons and manley rods, fp2 cams and FP bt28, 450cc injectors. Here is a log on my way to school (knock) and on my way back (knock2), was only at school for 30 minutes. All easy driving under 4k rpm's and under 35% throttle.

MAF and timing are zeroed out. The first log shows a ton of knock up and then it just happens to go away for the most part on the way back. Phantom knock? Wasn't fully warmed up? Or bigger issues?

did you tune at all after the cams and turbo install? 450s are small maybe your maxing them out?

it doesn't look like you logged throttle position, but I would check base timing, base fuel pressure, make sure you have good fuel filter in, and go through that. Most of the time I see silly timing issues its cause they set base timing wrong.

I'm not maxing them out, slipping clutch wont hold more than 10 psi. Fuel filter is brand new with the STM tank to rail kit. I've noticed that around 2200 rpm it knocks, I didn't have the problem before I swapped my 99 ecu into it to pass emissions and then swapped back. No tune so far cause of the clutch issue. It's just weird that after 30 minutes of driving its totally fine.

Yeah forgot to log throttle for the first log, but never got above 35% throttle.
