KR no matter what?

[Turboc3]

Hey guys and gals I'm new to the forum and to the tuning world. I just completed my first turbo build and am having some issues. The vehicle is a 2001 Gmc Sierra C3 and it's got an on3 performance kit on it modified to fit (it didn't fit like it was supposed to originally), it's got a circle d 3200 stall, 80lb injectors, 78/75 turbo, 2bar map and sd tune. I'm getting KR anytime I'm in boost pretty much, I just replaced knock sensors and harness and also ran 110 octane in it to make sure it wasn't real knock. Any help is greatly appreciated!

you should post up a tune and log

How do you post them? I'm not seeing an import or attachment option?

Figured it out

KR could be Bc if too much timing, not enough fuel, components touching body of vehicle giving false knock but sensors pick it up anyways..
These not the only causes but main ones I see

Also a pending or current knock sensor code will cause the knock retard channel to spike towards 8 degrees, which is the max knock retard allowed in this tune.
