The major car manufacturers spend many many man-years of testing and measuring to produce such
software. And of course they compromise between performance and efficiency - and sometimes they
cheat ( see the recent VW debacle..)

It's not easy

OK, good to know. So we can skip a lot of the discussion. Here is the last thing which you asked which doesn't seem to have been answered directly:

juntekind:
Please explain me this from gere im lerning

eg output = A * input1 + B * log (B' * input2) + C * sin(C' * input3)
What is A? The value of input1?
What is log and sin?

This is just an equation. It seems like a made-up example because it would be very rare to add logs and sines in one equation. (Where did this come from?) Log and sin are just mathematical functions. They take one input and output one number.

This equation is also a function, but it takes 5 inputs. In mathematics the small dash after the letter (') is called "prime" and it denotes a variable which is related to but different to the main one. So "B'" is read as "B prime".
