Data log files may be ECU data log file or PC data log files as this program treats

You can overlay other logged files on top of the current data & offset them with time so
can compare. Parts of the data can be marked & minimum, maximums, mean, Rate &
standard deviation are calculated. Can export as comma separated value
From data log files, can create XY plots with filters, Histograms & if logged LOAD,
Throttle & A/F ratio can create mixture plots. Mixture plots are shown as text & graphical
form. From mixture plots can correct "Base fuel delivery" table via the "F5" key. See
Edit-window for more details.
If table opened with same axis variables as logged data then an orange cursor shows the
table position.
To jump to graph TABS press "L" go forward & K go backwards.

disk when exiting. If logged variables correspond to table axis variables, the logger
cursor will be shown in the table.
