Torque Pro users familiar with custom PIDs and performance testing can now leverage similar techniques for the Chevy Bolt. Thanks to newly developed OBD2 PIDs, real-time power and torque data can be logged and analyzed using software like PerfExpert, offering valuable insights into the Bolt’s performance characteristics. This data can be used to understand how the Bolt’s electric motor and battery perform under various conditions, revealing key metrics like instant power.
Analyzing Chevy Bolt Performance with OBD2 PIDs
Initial testing with these PIDs reveals interesting aspects of the Bolt’s power delivery. Data logs clearly show how the motor controller manages torque, limiting it at lower speeds to prevent wheelspin and then gradually reducing it as the motor approaches its peak power output. This strategy maintains a relatively flat power curve across a wide range of speeds. The data also highlights the inverse relationship between battery voltage and power consumption, with voltage dropping as amperage and power demand increase.
This analysis utilized PerfExpert, incorporating published figures for the Bolt’s drag coefficient (Cd of 0.308), frontal area, and weight, along with the driver’s weight. A power correction factor near 1 was used, acknowledging the electric powertrain’s independence from air density. Interestingly, the resulting power curve suggests a potentially lower Cd than the published value, as the observed peak power occurs near top speed, implying less aerodynamic drag than anticipated.
Further testing conducted at different states of charge (SOC) revealed variations in performance. One test run at 83% SOC on a non-standard test road showed slightly different results compared to a previous run at a higher SOC on a verified flat road. The lack of PIDs during the higher SOC run prevented precise comparison, but it underscores the impact of SOC on performance.
Because PerfExpert calculates power at the wheels, these results provide a realistic picture of the Bolt’s performance after drivetrain losses. The data suggests that these losses are relatively low, which is expected given the efficiency of electric drivetrains.
Conclusion: Chevy Bolt Instant Power OBD2 PID Opens Doors to Deeper Analysis
Access to real-time power data via these new Chevy Bolt Instant Power Obd2 Pids provides valuable opportunities for performance analysis and tuning. By logging and analyzing this data with tools like PerfExpert, Bolt owners and enthusiasts can gain a deeper understanding of their vehicle’s capabilities and optimize its performance. Future testing and data analysis will further refine our understanding of the Bolt’s performance characteristics and potentially uncover hidden potential.
