(The reason being is that a notebook will not take the punishment of road racing)
I will be running endurance racing and internal buffer of 40 mins is shy of what I would like to record.
The s300 has datalogging to the SManager software built in via the USB port. Using a laptop the various ECU sensors can be datalogged, viewed, graphed and saved for later analysis.
Additionally the s300 has on board flash memory which allows a datalog recordings to be made without a laptop, for later access and download to a laptop. Multiple recordings can be made and stored in the s300 for a total of around 40 minutes of total datalogging time. .......
