Can anyone help me understand this better
My understanding was that petrols use the TPS for the base values and the MAP to correct it for the variable conditions such as outside temp
However the maps I find on my file seem to have a load range of 20-99 and since 99KPa is pretty much 1 bar (which is atmospheric pressure) can this mean it's using the MAP instead of TPS for the base values?
Does this mean the TPS is used somewhere to account for something acceleration enrichment instead?

Also confused as one of the maps I found which I thought could be spark table increases it's values as the load increases whereas the other one the load decreases which is my understanding is what it should do?

May be MAP refers to vacuum in the intake manifold here?

TPS readings are generally used more for transients (accel enrichment) than anything unless the system is designed to run strictly as alpha-N (TPS only).

Since it has a MAP sensor and MAP table, that's not likely the case.

Generally spark advance increases with RPM and decreases with load.
