Calibration Update
WARNING: This page is about a different car, the 2002 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
Calibration update is used to install a new calibration and strategy into a module. The updates are usually issued to fix a concern in the module software and would normally be addressed by a technical service bulletin (TSB). This method has been used by the PCM for several years. Other modules will be adopting this strategy as well.
