Connecting your AIM Solo DL to your Porsche for performance data logging can be done via the OBD2 port or by hardwiring into the CAN bus system. This article will explore the pros and cons of each method, focusing on ease of installation versus the amount and quality of data obtained, specifically for those seeking to utilize the Aim Obd2 connection.
AIM OBD2: Simple Setup, Limited Data
The easiest way to install your AIM Solo DL is by plugging it directly into the OBD2 port. This method is straightforward and requires no special tools or wiring knowledge. The device will then utilize the OBD2 diagnostic protocol to request data from your car’s ECU. However, this simplicity comes with limitations.
OBD2 is designed to provide access to a standardized set of diagnostic data. This means the AIM Solo DL, when using AIM OBD2, will only receive the specific parameters defined by the OBD2 standard. Furthermore, the data rate is inconsistent. The ECU responds to data requests as its processing load allows, resulting in varying intervals between data points. You might get data every 10 milliseconds, then 30, then 100, creating gaps and inconsistencies in your logged information. This can hinder detailed analysis, especially for high-performance driving where precise timing is critical.
CAN Bus: More Data, Consistent Stream
Hardwiring your AIM Solo DL directly into the CAN bus system offers a significant advantage: access to a much wider range of data points transmitted at a consistent, high frequency. The CAN bus is like a continuous stream of information flowing between various control units in your car. By tapping into this stream, the AIM Solo DL can passively listen and record all the data being transmitted, providing a comprehensive picture of your car’s performance.
This method relies on AIM’s ability to decode the proprietary CAN database file for your specific Porsche model. While this requires more advanced installation, the benefits are significant. You’ll get a higher data rate, typically at the frequency the data is transmitted by the car’s systems (e.g., 100Hz or every 10 milliseconds). This ensures a consistent and complete data log for accurate analysis. The richness of data also allows for deeper insights into your car’s behavior and performance.
Choosing the Right Connection Method
Ultimately, the best method depends on your specific needs and priorities. If ease of installation is paramount and basic data is sufficient, the AIM OBD2 connection via the OBD2 port is a viable option. However, for serious performance analysis requiring a comprehensive and consistent data stream, connecting directly to the CAN bus provides the necessary data fidelity, despite a more complex installation. While the AIM OBD2 connection is simple, harnessing the full potential of your AIM Solo DL for in-depth performance analysis necessitates tapping into the wealth of information available through the CAN bus.
