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?
