Controller family and application

An engine control computer manages functions such as fuel delivery and ignition timing using sensor inputs and programmed calibration data. That general role is a tentative association for this file, not confirmation of the behavior or changes in this particular revision.

The filename does not identify a vehicle model, a stock or modified variant, or a specific feature. It therefore should not be treated as proof of compatibility with another calibration that has a similar prefix.
