Datalogging parameters control the datalogging to on-board flash memory on the s300.
Datalogging
Enabling on board datalogging will automatically start datalogging once the start condition(s) are met.
Datalogging Start/Stop
Datalogging can be setup to start and stop in two different ways: using a unused ECU input as a switch, or based on engine parameters.
Using a manual switch will start datalogging when the switch is on, and stop once the switch is off.
Base on engine parameters will start datalogging once the start conditions are both met (engine speed and throttle). Datalogging continues until both the stop conditions (engine speed and vehicle speed) are met.
The flash memory has a write lifespan of at least 100,000 write cycles but it is not recommended to set datalogging on constantly.
