AiM Sports Solo2 DL Data Logging Lap Timer The Premier Data-Logging & GPS Lap Timer For Motorsports Enthusiasts The AiM Solo2 DL receives data from two satellite constellations, GPS and Glonass; this is a huge step forward since it is unbelievably faster and more precise than the previous version. Power-on requires only a few seconds and lap times are calculated within a 0.02-second tolerance thanks to 10Hz (ten times per second) GPS sampling. A sleek, newly-designed case with easier-to-use metal buttons add a premium look and feel to the world's most popular data-logger and GPS lap timer. The screen can be back-lighted in one of seven colors! The AiM Solo2 DL With An ECU Connection Solo2 DL -- the Solo with an ECU connection -- has over a thousand ECU protocols in its database. Easily connect your Solo2 DL to your ECU and get reams information with just one cable. In case your ECU protocol isn't in the database, no problem: an ECU Driver Builder is available in the included Race Studio 3 software, allowing you to create your protocol yourself. This gives you access to a huge amount of data from your car that can be overlaid with GPS data to create an incredibly powerful analysis and learning tool! Choose your ECU Cable: OBD2: the standard vehicle diagnostic port beneath your dash supplies the Solo2 DL with a wealth of information. This is the standard cable most people will use. CAN/RS232: the Solo2 DL can be connected to your CAN Bus for an even richer, broader spectrum of information than OBD2. This cable can require a bit more know-how to connect, however. Coil RPM: the Solo2 DL now features a digital input allowing to log RPM either from square wave signals (8-50 V each signal) or pulse signals (150-450 V ignition coil trigger – primary circuit).  Find Your Race Track Quickly and Easily Solo2 DL has access to a database of more than 3,000 tracks all over the world! As soon as it switches on, the Solo2 DL identifies its position, recognizes the starting line coordinates of the track, and is ready to start sampling lap times. If your track isn't in the database, no problem: the Solo2 DL will automatically enter into autolearning mode, figures out the characteristics of the track, and starts lap-timing anyway. Predictive Lap Time LEDs The new Solo2 DL's predictive lap time engine is now even more reliable. And with configurable RGB LEDs, it will give you a clear, fast indication of how your current lap compares with your best possible lap. That's functionality you typically find only on expensive driver-coaching electronic aids; now it's at your fingertips with the Solo2 DL! Race Mode Selection The AiM Solo2 DL can manage different types of races, such as the following: Speed races in a closed circuit Point to-point races Regularity Performance tests (0-100 km/h etc.) In each of these configurations, the Solo2 DL gives the relevant information during the race/test along with powerful data review immediately after each session. WiFi & iPhone Connectivity WiFi communication with your laptop is easy, fast, and with no connectors or cables. It's the best way to configure your Solo2 DL, manage the track database, and download lap data to your PC. Connect your Solo2 DL to your iPhone for quick and easy data analysis, managing your track database, etc. Post-Race Data Analysis With RaceStudio 3 After downloading on-track data gathered by the AiM Solo2 DL to your laptop, you can easily analyze that data in AiM's amazing RaceStudio 3 software. Compare laps, lines, driver and car performance parameters, and much more to learn where you can trim tenths and outrun your competition! AiM SmartyCam Data Integration AiM gives your SmartyCam the perfect connection: the Solo2 DL takes data from your ECU, merges it with GPS lap information, and transmits everything seamlessly to your AiM SmartyCam. The resulting video includes your ECU and lap data in a graphical overlay! Feel free to give us a call at (844) 438-7244 to discuss the cool new features and capabilities of AiM's latest, greatest compact data-logger/lap timer today!
