Set up RPM and Load axes

The RPM (X) and Load (Y) axes of the 3D maps must be set up before any calibration work is to

be done. The matrix for all 3D maps except the idle fuel and idle ignition maps is 23 (X) by 17

(Y). The set points may be linear or non linear. Most road cars with relatively mild tuning

characteristics use linear X & Y axes. On engines that are modified with narrow power bands

the non-linear set up is often used. The reason a non-linear set up is good for highly tuned

engines is because the airflow through them is very non linear. The set up of the X & Y axes

allows the tuner to accommodate the non-linear characteristics of the engine by placing the set

points for RPM and Load closer together in the region where drivability is critical.
