When I'm stabbing the throttle, I see knock retard kick in. I have no idea why? Is there some program logic that adds knock retard based on other readings?

Disable burst knock and see if it goes away.Originally Posted by Scorp1us
Cool thanks.
Nope, I still get it.
I tried changing all the parameters that would make sense.
Here is a log.
I just reviewed your log. If you could post your bin, I could tell more about what is going on. I see some AE activity and I believe that is because of your cam. You may have to adjust your map difference to enable AE at idle parameter. I also notice you are in open loop in the log. Do you have your bin set for open loop at idle? I put a slightly larger than stock cam in my build and had to tweak the AE settings. At idle AE was active quite often and it caused my plugs to be fouled because of the extra fuel.

I have only tuned the spark timing to match the distributor specs of the IH dist. -- EXCEPT idle and 400 RPM to stop a stall.
I have only tuned fuel for best sounding idle. The rest is GM
Idle cells are:
RPM -- MAP
400: - ridiculous advance for saving idle from a stall
600: 45-60 (at start of tuning, it was 60-65, adding fuel brought it down to 45)
800: 45-50
1000: 45-50
1200: 35-40
1600: 30-35
Because I need to run rich with the cam at idle I have open loop idle enabled.
What do I need to change to have AE work properly?
What is the deciding factor for the software to switch from the idle to open throttle VE tableand Main spark open/closed throttle tables?
