AEM Tuner Environment
Basic Terminology
Calibration File
– The calibration file is what the tuner modifies and will be specific to the engine
setup.
Options
– Single values that are set by the user to change the operation of an EMS.
Channels - Channels are data for viewing and logging. They are a window to the engine. They
tell you everything the engine is doing and what all of the sensors are seeing. This window is
one of the most valuable tools in helping to tune the engine.
Tables
– Tables are two dimensional data sets that define one value as a function of another.
Maps
– Maps are three dimensional data sets that define one value as a function of two others.
Tabs
– Tabs are screen templates that the user can create and edit to group sets of calibration
data as needed.
Workspace
– User defined AEM Tuner configuration settings that include in part: Basic
application preferences, the display settings, the number of tabs displayed and the tab
configuration, color preferences, unit preferences, hot keys, etc.
