Trying to get my truck tuned up to where I can at least drive it when needed, will be a bit before I make it in for a dyno tune. Stage 2 cam, rebuilt bottom end, stock heads with a valve job. Motor is an lh6, aluminum block, 07 model with DOD delete. Starts idles and runs fine, no missing or obvious issues, but I keep having random knock that I can't get to go away. I've took out timing multiple times and it seemed to not change anything, so I even flashed the stock timing tables back in it and it still is doing the same thing. I'm not sure if maybe my knock sensors are picking up something they shouldn't or what the issue is. It seems to knock reliably when you first put the gas to it, before the rpms start rising. I would call it "tip in" but not sure if that's actually going to be called "tip in knock". Also at random times, usually after making a stop and letting the truck sit for 10-15 mins, when I start up and take off again, I get pretty big bursts of knock at random spots, that don't seem to replicate each time I'm in those cells. Think dialing in the fueling first would address some of this knock or do you think something else is going on? There's no audible knock and no I don't have any way to verify it's actually knock outside of my stock knock sensors currently.
I've been reading on Burst Knock and I think that is what is happening at low RPMs when I step on the gas. How do I get it to go away? I see in other threads people disabling BK... Would that be the place to start to diagnose if it is actual knock or just burst knock? I've attached 3 logs and my current tune, does anyone have any suggestions on what direction I need to be heading with this?
Thanks for any help!
