Thanks Lionelhutz!

attached below is the same type of graph as last time but it has the updated cell boundaries I used to generate this new data.

the PDF is just a simple table that counts the number of times each cell was "hit".

it has definitely improved as now all 16 cells are utilized versus just a few.

The lower MAP setting I used of 45KPa seems a little high. Your suggestion of 30KPa as the lower bound is even less than the factory setting of 32KPa. With the factory settings it rarely ever touched any 0-32KPa cells .
