Excessive IAT forced the ECU to retard ignition timing (a good thing, as it saves the engine!) and add extra fuel to prevent detonation. As you can see, the MPVI Interface Standalone Data Logging Function is a pretty valuable tool to have at your disposal.
In the screen-shot below you can see that "Read All Logs" was clicked and the moment the computer was reading the logs from the MPVI Interface cable was captured. The files will then be listed below the "Log:" heading shown highlighted in blue.

3. Reading the Data Logs: In the screen-shot below you can see that "Read All Logs" is highlighted. Clicking on this will read all of the data logs stored in the MPVI Interface cable and present them in the blank window to the left. You can then select which log you wish to view from the list. Remember when performing standalone data logging to press the Record and Stop Recording buttons on the MPVI Interface to gather the data you're after!
