This is the log file play back and analyzer panel. Only data that is actually logged can be observed. For best results, you must log rpms, pulse width, o2 voltage, knock sum, boost, and timing advance.

The controls on this panel have the following functions:

The following pages show a progession of how to use the Analyzer with the PMS

  1. This page shows an open .DAB log file that has been analyzed ('>>').
  2. This page shows an empty PMS map screen
  3. This page shows the PMS map screen and the "active" cells for the log file record are highlighted in red
  4. This page shows the Analyzer activated (the log data is displayed in red). The o2's have been adjusted from .92 to .86
  5. This page shows the PMS map which reflects the changes in the fuel map to achieve a .86 o2 voltage level
  6. This page shows the 2d chart results
  7. This page shows the 3d chart results
    1. Shows grid option 1
    2. Shows grid option 2
    3. Shows the data rotated in 3d
    4. Show the detail behind a 3d data point (just click on the data point)

If you use the Apexi AFC and/or ITC controllers, the operation is the same, but the controller panels which display the fuel and/or timing maps are different.

The Player also supports scrolling strip charts for all of the loggable elements. These operate just like the strip charts in the logger.

The analyzer is what sets Tunerstein apart from all of the 'others'. By gliding the mouse cursor over a cell which contains data, the log file entry represented by that cell will be displayed. Clicking the cell will "lock" it and the displayed log file data turns red.

This indicates that the tuning simulator is now active and the vertical scroll bar is enabled. Drag the scroll bar up and down to adjust the displayed o2 voltage. As it changes, the pulse width data also changes. If 'animate' mode is turned on, the fuel controller map is adjusted to indicate your new changes, and all of the cells in the analyzer are re-interpreted using the new fuel controller map.

This lets you play "what if" games without actually driving the car!!!!

For this to work, the fuel controller map must be the one used when the log file was created. If not, the accuracy of the simulator is compromised and using the resulting map COULD LEAD TO SEVERE ENGINE DAMAGE!!!

To "undo" your changes, simply click 'reset'.

You must log AT LEAST rpms, o2 voltage, and injector pulsewidth to use the analyzer with TMO log files.
