Definition of Terms
Calibration Update: Some modules are designed to be flashed or reflashed with completely new software packages. The process of re-flashing a module is a calibration update.
Programmable Parameters: These are options that are contained within the existing software. These include items such as tire size, customer preference items, and anti-theft options. The current settings are downloaded from an existing module then uploaded to a new module. The new module can also be configured using the diagnostic tool. Programming parameters is very different from updating calibrations as no software is changed, only the options already contained in the software.
