Opinions wanted ( analysis of the effects of spark advance va riation on vacuum)

[cmillard at crutchfield.com]

No sir, I'm done open loop idle before (PowerEnrichment enabled via TPS %)
to control the fueling. 
 
I'm attempting to optimize spark - which by the only definition I feel I can
monitor ( no EGT, no EGOR, no cylinder pressure sensor) it the vacuum level
(-MAP)
I'm trying to stay closed loop idle, just for a change.
 
Please let me know if I'm unclear- Thanks,
-Christian
