A:F Data Source
When recording Generation 7+ ECM data, this switch controls the source of the Air to

Fuel Ratio data channel. Setting this switch to the GEN 7+ ECM position will cause
the Data Logger to record the air to fuel ratio from your Generation 7+ ECM.


Setting this switch to the INTERNAL MEASURED A:F RATIO position will cause the

Data Logger to record it’s own internal air to fuel ratio.

Sample Rate
When recording Engine Analyzer data only, the data sample rate is selectable
between 10 and 250 samples per second, depending on the model of Engine

Analyzer. When recording Generation 7+ ECM data along with the internal Engine
Analyzer data, the sample rate is fixed at 20 samples per second.


Recording Time

This field is not programmable at this time. Recording time is currently determined
by the amount of time that the Data Logging Enable input is activated and the

sample rate at which the data is stored. The following charts list the recording times
available for both single and dual channel models based on various sample rates.
