3. Select Datalogging.
4. Select the values you wish to log, using the OK button to select/de-select items.

List of recommended values:

From Stratified

VALUE DESCRIPTION:
Accel. Pedal Pos. Accelerator pedal position (this is direct pedal input before translations)
Actual AFR Wideband front oxygen sensor reading converted from Lambda to AFR
Airflow Mass The calculated airflow through the engine and is used for almost all flow based tables.
