The AiM Sports Solo 2 DL GPS Lap Timer is a log timer with an internal data logger that combines small dimensions, usability, and logging capability. The Solo 2 DL manages hardware ECU connections, as well as all of the communication lines. Its huge database includes over 1,500 protocols you can load in your Solo 2 DL. (If your vehicle does not have an ECU, a power cable is included so you can connect the lap timer to an RPM wave and synchronize RPM to the position on the track.)
