Try clicking on the "3D View" button

The Spark-Table tab is specific to the all firmwares (except MSnS-Extra which uses 12x12 tables). It shows the SparkAngle BTDC table used for fueling calculations. Values are changed by either typing in the value into the entry and hitting enter, using PgUp/PgDn +/- or clicking on the up/down buttons (spinbutton views only). The user can also click on the 3D view button to see a true OpenGL 3D projection of the table that can be rotated and moved with the mouse to best visualize the table. The table can be edited in the 3D view with the arrows (arrows to move, +/- Pgup/PgDn to alter values, the +/- keys will change the value by 1 unit, the PgUp/PgDn change them by 10 units)
