If a range of cells (multiple rows and columns) are selected and the “Interpolate” “cell-fill” option is

selected the ECU will use the value in the cells at the bottom left and top left corners, bottom left and

bottom right corners and the bottom left and top right corners of the entire range and interpolate the

numbers in between so that the values are linear.

Example Air Fuel Ratio Tables

Example air fuel ratio tables, for a normally aspirated street engine, a super charged engine and a

turbocharged engine, are shown below. The air/fuel ratio values in these cells can be used as base lines

for each of the engine configurations. The “Example Maps” below are segmented into engine

operating areas (Cruise, Idle, Wide Open Throttle, etc.) to help the user understand what part of the

map is “active” under different driving conditions (engine speed and load combinations).
