You'll gain more insight into your driving by comparing at least two different laps using the Race Studio Analysis software. Once the plots are overlaid you can start to make some deductions about what you as a driver are doing behind the wheel and start to answer questions like, could I brake later here, or carry a higher minimum speed through that corner there...etc.

The Aim Solo DL connects to your OBD port and has the ability to record a variety of data channels from your ECU like, RPM, Speed, Brake Input, Throttle position, coolant temp, oil pressure.
