Auterra’s OBDII software and interface offer a powerful solution for car diagnostics and data logging. This review explores its capabilities, focusing on real-world testing and data analysis. Connecting through the OBDII diagnostic port, the Auterra system allows for comprehensive monitoring of vehicle vitals without the need for numerous physical gauges.
Unlocking Vehicle Data with Auterra OBDII
The Auterra Obdii software boasts impressive functionality, including comprehensive diagnostics and detailed data logging. One key advantage is its ability to record and export data, which can then be converted into an Excel file for further analysis and graphing. This feature allows users to visualize sensor readings over time, providing valuable insights into vehicle performance. Up to five sensors can be monitored simultaneously, offering a comprehensive view of various engine parameters.
Real-World Testing: 0-100 Run Analysis
To evaluate the Auterra OBDII system’s capabilities, a 0-100 mph run was conducted on a near-stock vehicle (only modification: BFI – Big Fuel Injectors) with the software monitoring RPM, speed, and Bank 1 Sensor 1 readings (likely the primary O2 sensor). The outside temperature was approximately 76°F with high humidity, and the MAF (Mass Air Flow) air temperature hovered around 97-99°F during the run. Notably, the MAF temperature consistently remained about 20°F above the ambient temperature while cruising. It’s speculated that the heat shield and BFI contributed to keeping intake temperatures lower, but further testing and comparison are needed to confirm this.
The logged data provides a glimpse into the air-to-fuel ratios during acceleration. The accompanying data table (see below) includes RPM, speed, and the corresponding voltage reading from Bank 1 Sensor 1. This information may be helpful in understanding the voltage-to-A/F (Air/Fuel) ratio conversion, shedding light on the engine’s fueling characteristics under load.
Data Table: RPM, Speed, and O2 Sensor Voltage
The table below presents the raw data collected during the 0-100 mph run. Each row represents a specific point in time, recording the RPM, speed, and corresponding voltage from Bank 1 Sensor 1. This raw data can be further analyzed to understand engine performance and potential areas for optimization.
718 r/min 0 MPH 0.85 V
854 r/min 0 MPH 0.72 V
751 r/min 0 MPH 0.81 V
