For the iat heatsoak issue, each manufacturer apparently deals with some form of "Heat soak". The term is loosely used to describe a high reading from radiant heat from the intake manifold affecting the sensor. Newer materials have eased the affect from this but do not prevent it, aluminum has the greatest heat transfer effect.
Many oem have moved to using 2 separate iat sensors, one in the MAF or airbox and one in the manifold. At wot only the manifold temp is used, in most other conditions the signal from each sensor is blended (Or some type of trim table is used) to get a "more realistic" reading.
((I'll be honest there was talk of laminar flow and something about eddycurrents that in terms of air flow I don't fully grasp.))
Others use some form of blended table using the air temp and coolant temp sensors. In wot only the iat sensor is used, in all other conditions the blended reading is used. Usually in this set up the sensor is not in the manifold and the blended table us used to get a more realistic reading of slow moving air in the manifold.
For our purposes megasquirt actually does have the ability to blend tables using multiple sensor inputs for the iat. We could use a 30% blend with clt temp, this would make the reading more realistic in all conditions. Under wot the clt blend is ignored and the table reverts back to air temp only.
Took alot of legwork to get this information, I apologize if I came off as unreasonable in my last few posts.
