motec also does site interpolation, which means it picks the average between the 4 closest cells on the map and trims, so very often you will see a ignition value which isnt exactly whats in a particular cell or compensation, but its calculated based on the interpolation of all those parameters.

on logging you can log the ignition trim values and base ignition.

and if you want to compare manifold pressure against 'load', its close enough, but its actually calculated as manifold pressure / barometric pressure. so 100kpa (technically wot on a NA car, might actually only be 99 % load due to baro.
