How does the ECM round intermediate values
Such as a MAP of 25. Does it go up to 30 down to 20 to get a value off the fuel tables? What about MAP of 21?
Same with RPM's. Where does it round at?

Ken is right, in fact, the same thing happens when you have an RPM value between two values - the ECM will compute the "average" between the values (whether it is RPM or Kpa). The closer it is to one of the "boundaries", the closer it will be to the value.
It does this with Spark and VE.
