Engine control role

An engine control module uses its calibration to manage functions such as fuel injection and ignition timing in response to operating conditions. These controls affect how the engine starts, idles and responds to the accelerator.
The Axio filename provides a useful application clue, but it does not establish the exact vehicle year, market or ECU hardware. It also does not identify a change made by this particular calibration revision. Neither filename names a modified variant or a special operating feature.
