For E90 M3 enthusiasts pushing their machines to the limit on the track, understanding vehicle data is paramount. The AIM Solo DL, a powerful data logger, offers invaluable insights into your car’s performance, directly accessible through your BMW E90 M3’s OBD2 port. Let’s delve into how this integration unlocks a new dimension of track day analysis and improvement.
The AIM Solo DL stands out as a user-friendly device capable of tracking and logging a wealth of data directly from your car’s systems. For E90 M3 owners, this means accessing crucial information via the car’s communication network. While the E90 M3’s sophisticated CAN bus system offers the most comprehensive data set, the OBD2 connector still provides a valuable stream of information, perfect for track day analysis and performance enhancement.
Here’s a glimpse into the data channels the AIM Solo DL can monitor and record from the CAN bus of an E90 M3, offering a more in-depth look compared to standard OBD2:

As shown in the AIM documentation, connecting directly to the CAN bus offers a richer data stream with up to 28 channels compared to the more limited 9 channels available through the OBDII connector. You can explore the detailed documentation here: AIM Solo DL BMW OBDII/CAN Connection Guide
Despite the limitations of OBD2 compared to direct CAN bus access, the AIM Solo DL still provides essential data for track day analysis. You can customize your display to focus on the metrics that matter most to you. For instance, a window displaying key temperatures and G-forces can be incredibly insightful:

This display allows you to monitor:
- OILT (Oil Temperature): Critical for understanding engine health under track conditions.
- ENGT (Water Temperature): Another vital engine temperature to prevent overheating during intense driving.
- EXTT (Ambient Air Temperature): Useful for understanding how environmental conditions affect performance.
- ACCT (Lateral G-force): Measures cornering forces, helping you understand your car’s handling and your driving technique in turns.
Another popular and highly beneficial display is the Time Delta page. This feature provides real-time feedback on your lap performance compared to your fastest lap within the current session.

The Time Delta feature is invaluable for:
- Real-time Performance Feedback: See instantly if you are gaining or losing time compared to your best lap.
- Session-Specific Analysis: Focuses on your current session, providing relevant and immediate performance data.
- Driver Improvement: Helps you adjust your driving in real-time to optimize lap times.
Beyond real-time displays, the true power of the AIM Solo DL lies in its data logging capabilities. While glancing at live data can be tempting, maintaining focus on driving is paramount on the track. The AIM Solo DL excels at recording data for post-session analysis, allowing for in-depth review and performance optimization.
The device also offers Predictive Lap Time functionality, further enhancing its usefulness on track.
While immediate data feedback has its place, the ability to analyze logged data after a session is where significant performance gains are realized. Imagine being able to precisely quantify aspects of your driving, moving beyond subjective feelings to concrete data.
For example, consider the question of throttle application on a specific straight. Instead of guessing, data logging provides definitive answers. By reviewing the data, you can accurately determine throttle percentage, braking points, and other crucial parameters, eliminating guesswork and ego from the equation. This data-driven approach is invaluable for objective self-assessment and targeted improvement.
In conclusion, the AIM Solo DL, even when utilizing the OBD2 port of your E90 M3, is a powerful tool for track day enthusiasts. It provides essential real-time feedback and, more importantly, records comprehensive data for post-session analysis. This combination empowers you to understand your car and your driving at a deeper level, leading to tangible improvements in your track performance and lap times. Unlock the full potential of your E90 M3 on the track by harnessing the power of OBD2 data with the AIM Solo DL.
