Spark vs boost

[StealBlueSHO]

Stealblue on your car if we lowered boost the tables would've commanded more spark but since I'd say we were within the efficiency of the turbos we were moving more air at the higher boost and that coupled with running max spark is why I think it ran well

So spark follows load tables.. and based on datalogging the load PID, the load PID appears to follow the MAP pid or vice versa exclusively 99% of the time. I have seen cases during a log when I have had one my vacuum lines pop off (Thanks LMS for the weird blow off valve issues on the 4+x tune that doesn't allow the BOV to open correctly) causing the ECU to drop the WGDC to 0 effectively killing off all the boost.. which then because my load had just plummeted my spark advance went sky high I think into the 40's or so...

Point being, if spark follows the load tables.. and there has been mention that the logic in our vehicles pushes spark right up against the knock sensor as it scales it up, as a tuner, do you have control over how much spark gets added? In other words, can you program definitively that max spark would be 20 degrees for this given load?

Not exactly related to my original question... but curious non the less...

The tune is essentially doing what it should, it kills off the boost if the situation warrants it and if there is no boost timing is increased because the load fell off.
That's how it's written so I'm not sure where the question is that?

LMS, I was using an example of something that happened to my vehicle to help clarify and give context to the next portion of my post which contains the question. Which is based on a statement that spark follows load... and to help MY understanding of how these cars determine how much spark is needed and if in tuning these ecoboost motors, the tuner has the ability to define what the maximum amount of spark at any given point. OR if the knock sensor will keep adding additional spark if it can... which AJPTurbo answered for me.

Yes, the tune did exactly as it was supposed too, I was not saying it didn't.. I am sure it follows what the stock settings allow for as well..

And yes, its a known issue with the 4+x tune that the BOVs don't open/close on time causing that weird duck call like sound.. sometimes they don't open at all... causing the excess pressure to stay in the system.. which again.. caused my vacuum line to pop off which helped me learn more about how these cars handle a no boost situation!
