For Chevy Bolt EV enthusiasts and owners looking to dive deeper into their vehicle’s data, a significant update has arrived. This comprehensive update dramatically expands the accessible data points, offering an unprecedented level of insight into your electric vehicle’s performance and health. If you’re utilizing OBD2 apps to monitor your Chevy Bolt, prepare to explore a wealth of new information.
Enhanced Data Access for Chevy Bolt EVs
A substantial expansion to the list of known Parameter IDs (PIDs) has been implemented, increasing the data points from approximately 60 to over 240. This update excludes redundant cell voltage and Fahrenheit readings, focusing on unique and valuable metrics. For users of apps like EngineLink, Fahrenheit options have been added for convenience, while Torque Pro users will benefit from automatic unit conversion.
To effectively manage this vastly increased data set, a harmonization of PID names has been carried out. It is crucial to clear your existing PID list before importing the new one. Failure to do so will result in a cluttered and duplicated list, leading to “Missing PID” errors on your custom dashboards. While recreating dashboards may require a few moments, the enhanced data access and improved organization significantly outweigh this minor inconvenience. Consider taking screenshots of your current dashboards to easily rebuild them after the update.
Key New Data Parameters Unveiled
This update unlocks access to a wide array of previously unavailable data, categorized for easier navigation and understanding. Notable additions include:
- DCFC (DC Fast Charging) Insights: Monitor requested current during fast charging sessions.
- Comprehensive HVAC Details: Access detailed data regarding your heating, ventilation, and air conditioning system.
- Pump Performance Metrics: Observe the operational details of various vehicle pumps.
- Cooling Fan Status: Track the activity and performance of the cooling fan system.
- Expanded Battery Monitoring: Delve deeper into battery health with more pack, module, and cell level data, including State of Charge (SoC) variation, battery resistance, and high/low cell voltages.
- High-Resolution Current and Voltage Readings: Obtain more precise measurements of electrical parameters.
- Charging System Data: Access a broader range of parameters related to the charging process.
- Temperature Sensors: Monitor a greater number of temperature sensors throughout the vehicle.
- Transmission Data (Experimental): Explore transmission-related data, including torque readings (note: these are under validation and may initially display inaccuracies).
These additions provide a more complete picture of your Chevy Bolt EV’s inner workings, empowering you with deeper diagnostic capabilities and performance insights via your Chevy Bolt Obd2 App.
Important Update Notes and Considerations
Within the updated PID list, certain prefixes are used to denote specific categories:
- ‘-‘ Prefix: Indicates PIDs that are identified but considered less critical for general monitoring. Examples include Phase U, V, W currents, which, while measurable, fluctuate rapidly and may not offer practical insights. Also included are readings from shifter pressure sensors, which capture data like pressure applied to the shifter in X and Y directions – interesting but perhaps not essential for most users.
- ‘?’ Prefix: Marks PIDs that are identified but may be unreliable, potentially broken, or require formula verification. The accompanying Google Sheet (linked within the project documentation) provides detailed notes on these PIDs, encouraging community collaboration to decipher and validate them. It’s important to note that some PIDs may be inherently flawed and provide inaccurate data even when accessed with professional tools like GDS2.
Furthermore, while efforts have been made to shorten PID names, some may still appear lengthy. Ongoing work is focused on creating more concise names for improved readability within OBD2 apps.
Embrace this update to maximize your Chevy Bolt OBD2 app experience and unlock a new level of understanding of your electric vehicle. Remember to clear your old PID list and prepare to explore the wealth of new data now at your fingertips.
