Ok today I did data log it for partial throttle and,

45-55% throttle
6-10psi
18-22 deg advance
EGT 1250-1300


I did this several times and always got the same result. The advance would go right to 22 and then drop down to 19.5-18. A few times it would drop lower to around 16 deg. But everytime it would go to 22 deg for a moment right away.

I never saw it higher than 22 deg. under boost

WOT and 18psi I get 18-20 advance.

What do you mean by clarify what dictates the loop state?

Throttle position is how the ECU knows when to go close and when to go open loop.
