Default Knock Knock need help spark retard

Hi im getting knock retard whenever i give the throttle a quick stomp, but go easy there is no knock. I used datamaster to see but i don't know maybe there is a clue there that might tell me where to start looking. Far as I know I dont ever hear anything or feel, so if it wasnt for the datamaster I would not know. The exhaust is loud but ive been down that road looking for noises. The rockers I checked and none are loose, (Stock ones)

thanks

Burst knock retard is where you will want to go to fix this. It pulls timing for large throttle transients and will fix your issue

thanks. I guess one thing i thought of was put a resistor in the knock sensors place. Then rev the motor quick just like before then I defenitly know its burst knock.

KR is only normal in the sense that it is normally tuned out, its not acceptable.
