In both Solo and Solo DL, you get s/p/G data (GPS speed, GPS position, and G's) + lap times and predictive lap timing.

Solo DL, in addition, allows you to connect to and download data from the ECU.

For the M3, here are the additional data channels you get using a CAN connection to the ECU. Some of these data channels are extremely valuable, i.e. Gas Pedal Position, Brake Pressure, Steering Wheel Angle, etc.

For example, when braking, brake pressure is a more precise indication of your brake point, so is steering wheel angel for cornering.

Are you spinning your inside wheel coming out of a corner? Just check the individual wheel speed.

RPM
Gas Pedal Position
Speed, Indicated
Speed, Real
Wheel Speed, LF
Wheel Speed, RF
Wheel Speed, LR
Wheel Speed, RR
Steering Angle
Clutch Switch
Brake Switch
Brake Pressure
Brake Pressure, LF
Brake Pressure, RF
Brake Pressure, LR
Brake Pressure, RR
Engine Coolant Temperature
Oil Temperature
Outside Temperature
Manifold Absolute Pressure
Gear
Acceleration, Long
Acceleration, Lat
Gyro
Fuel Injection
Distance
Fuel
Battery

OBDII connection on the other hand, only gives you about 9 channels of data.
