Do you know what? All of you.
There is little point putting a post on this website as most of you are so childish and pathetic, you can't stand to hear an opinion other than your own.
Not a single post has helped me before someone starts bickering or crying to mummy.
For ****s sake - grow the **** up and post informative, intelligent comments.
It's ok to disagree, but replying like a child makes you ALL look like ****s.

MAP = Manifold Absolute Pressure.
So knowing the ratio of atmospheric to boost, the ecu can calculate the equivalent airflow. A MAF sensor is non-linear and has to be "scaled" to convert the flow rate (voltage) into an ecu input.
AFAIK

yes thats correct
P= the absolute pressure of the engine
V= volume been measure ie manifold size
N= mass of the air
r= real gas constant for air
T= the absolute temperature of the volume been measured

When swapping to a MAP sensor, is a charge temp sensor fitted as well for use in the calculations?

Having fitted and mapped a few of these now - i agree they are a very good option.
With regards to them making the car smoother - a move to MAP based ecu can do this particularly in the transient areas coming off and onto the throttle. Obviously the mapper has to make it so with what they do but in essence the ecu makes it easier to get a good result.
