For Chevy Bolt EV enthusiasts and owners who love to dive into the details of their vehicle’s performance, the OBD2 port is a treasure trove of information. Recently, a significant update has expanded the data available through your Chevy Bolt Obd2 Port, offering a much richer understanding of your EV’s inner workings. This update is a game-changer for anyone looking to monitor their Bolt’s health, charging efficiency, and overall performance.
What’s New in this OBD2 Data Expansion?
The latest update dramatically increases the number of available PIDs (Parameter IDs) accessible via the Chevy Bolt OBD2 port, jumping from around 60 to an impressive 240. This substantial increase opens up a wealth of new diagnostic and monitoring possibilities. Imagine having access to almost four times the data points compared to before!
This expansion isn’t just about quantity; it’s about quality and organization. The newly added PIDs are thoughtfully categorized and harmonized, making it easier than ever to navigate and utilize this extensive data. Here are some key highlights of the new data categories now available through your Chevy Bolt OBD2 port:
- DCFC (DC Fast Charging) Insights: Get detailed data on requested current during DC fast charging sessions.
- HVAC System Deep Dive: Access comprehensive information about your Bolt’s Heating, Ventilation, and Air Conditioning system.
- Pump Performance Metrics: Monitor various pump systems within your vehicle for optimal operation.
- Cooling Fan Details: Keep tabs on your cooling fan’s activity and performance.
- Expanded Battery Cell Data: Delve deeper into battery health with more PIDs for pack, module, and individual cell data. This includes crucial metrics like State of Charge (SoC) variation, battery resistance, and high/low cell voltages.
- High-Resolution Current and Voltage Readings: Obtain more precise measurements of current and voltage within your Chevy Bolt’s electrical system.
- Comprehensive Charging Data: Access a broader range of parameters related to the charging process, providing a more complete picture of your charging sessions.
- Temperature Sensor Galore: Monitor a wider array of temperature sensors throughout your vehicle.
- Transmission Insights (Experimental): Explore new data related to the transmission, including torque readings (Note: These are still under validation).
Important Considerations for Utilizing the Updated OBD2 Data
To fully leverage this expanded dataset from your Chevy Bolt OBD2 port, it’s crucial to take a few key steps. Due to the extensive changes and harmonization of PID names, it’s highly recommended to clear your existing PID lists in your OBD2 apps (like Torque or EngineLink) before importing the new, updated list. Failing to do so can result in a messy merge of old and new PIDs, leading to duplicates and “Missing PID” errors on your dashboards.
Action Required: Dashboard Recreation
Unfortunately, this update requires a bit of upfront work. You’ll need to recreate your custom dashboards in your OBD2 app after importing the new PID list. While this might seem inconvenient, the significantly enhanced data access and improved organization make it a worthwhile effort. Consider taking screenshots of your current dashboards before clearing them to make the recreation process smoother.
Exploring the “Useless” and “Questionable” Data
The update also includes PIDs categorized with prefixes to indicate their utility and reliability. PIDs prefixed with “-” are considered less interesting or potentially less useful for typical monitoring. An example highlighted is the Phase U, V, W currents, which fluctuate rapidly and may not provide meaningful insights for most users. Similarly, data related to shifter pressure sensors is available but might be considered niche.
PIDs marked with a “?” are those where the data might be broken, the formula is uncertain, or the readings are questionable. These are areas where community collaboration and further investigation are encouraged to decipher their meaning and potential usefulness.
Looking Ahead: More Chevy Bolt OBD2 Port Data on the Horizon
This update is a significant step forward in unlocking the potential of the Chevy Bolt OBD2 port. The developers are committed to continuous improvement and have hinted at more updates to come. This ongoing effort promises even greater access to valuable vehicle data for Chevy Bolt owners in the future.
By embracing this updated PID list and understanding the expanded data available through your Chevy Bolt OBD2 port, you can gain a deeper understanding of your electric vehicle, optimize its performance, and stay informed about its overall health. Dive in and explore the wealth of new information now at your fingertips!
