Default Knock retard extremely bouncy in open loop, but in closed loop....

I am using the Aeroforce Inteceptor and there is 3 different knock retards I can use. Only one of them worked so I'm assuming that is the right one.

Anyhow when I first start the car knock retard is bouncing anywhere between 3-12* at Idle. However when the car warms up and assuming in closed loop at Idle it was anywhere between 2-5*. When I barely press on the gas it almost always goes to 0* retard. Now I haven't had time to actually get on the highway to see what it does at WOT. What do you think?

post this in the computer tuning and diagnostic section. you'd probably get more responses. i would say adjusting the burst knock settings should help. especially the burst knock enable %diff airflow threshold as you have a healthy cam in there. what's your compression ratio?

i tune my car but im no expert. i had a bunch of knock when i first got started and modifying the burst knock tables corrected it.
