Tips for tuning:
The table is an offset to the main Spark Advance map. It is based on coolant temperature
in degrees C. or degrees F. (Whichever you have chosen as your desired units of
temperature in the application settings.) A value of "0" means that no change is being
applied to the base map. Enter the values in degrees positive (more advance) or negative
(less advance). Keep the values small. If a large value is required, it probably means that
your base spark advance calibration is not optimized, and you should adjust the main
spark map further.
IAT Spark Trim Table (Pro Option Only)
In Speed/Throttle (Alpha-N) mode, Speed/Pressure (MAP-N) mode, or Speed/Density
mode - there is the ability to adjust a global trim for spark advance based upon IAT. This
can be useful if ignition characteristics change greatly with ambient air temperature.
While not often needed, the
IAT Spark Trim Table can be helpful in providing a global
spark retard for a very hot intake charge in order to help avoid detonation.

means that your base spark advance calibration is not optimized, and you should adjust
the main spark map further with a representative charge temperature.
