Knock retard

[JackBauer]

Got a 16 Procharged cammed SS Camaro. Keeps throwing a P0324 Knock system code. Replaced both sensors. Nothing under the car is rubbing to cause false knock. It likes to pull timing at WOT and part throttle. LT4 HPFP, LT4 LPFP and LT4 injectors, AUX pump on a hobbs switch.

Yikes.

This thing is like prime AFR for melting down your motor, with quite a lot of timing, and what looks like legitimate knock.

I'd start by taking timing out of the tune ASAP and get the fueling in order. Honestly, and i'm only saying this so you know how serious I am. I can't believe the engine survived that log.

Is there some where time wise that you are seeing that. From what I am seeing, i don't see anything that screams at me. I'll admit not sure what I am doing, attempting to learn, thats the reason I'm posting here.

Learning on a cammed, power adder, LT1 is a good way to nuke the motor…. If you’re new to these torque based controls I’d suggest you pay a pro to do your tune. Most are great about working with you and answering questions. Look at what they do vs your tune, ask some questions, and do a bunch of reading on these forums. Then you’ll be equipped to make tweaks to your tune yourself as time goes on.

I don't see too much timing honestly according to the commanded timing plus flex fuel timing. But it is definitely too lean. However, you're already out of injection window on E50. Back it down to E30 and add more fuel. You want Lambda to about .82 on that setup on E30-E50.

Knock Retard can be caused by injection timing being too early or too late. I'm not sure what cam you have in there but I would be aiming for 350-355 SOI and 160 EOI. If you still have knock once you fatten up the fuel and shorten the injection window, then you have another issue. You could have a mechanical issue or a torque model issue. Not sure how long you've had the car but if you keep tunning it like this, its going to pop.
