The Afx Products 34t5 Bluetooth Obdii Scan Tool is a powerful diagnostic tool that allows users to monitor and troubleshoot their vehicles. This comprehensive guide explores its features, functionality, and recent updates, including a crucial bug fix for boost detection and the addition of a gear indicator.
Enhanced Boost Detection and Gear Indicator Functionality
A recent update to the AFX Products 34T5 addresses a significant bug in the boost detection function. The “zref_IsBoost” PID now accurately reflects boost levels, starting at 96 kPa and extending to the OBDII mandated limit of 255 kPa. This early start point helps identify potential “boost threshold pinging” often caused by early tuning or low-quality fuel. Consequently, the “MX5_Knock Retard – Boost Referenced” PID also benefits from this fix, providing more accurate readings.
Furthermore, the update introduces the highly requested “MX5_Gear Indicator” virtual PID along with several supporting reference PIDs. This feature requires specific configuration based on transmission type and final drive ratio.
Configuring the Gear Indicator
For users with the factory six-speed manual transmission and stock final drive ratio, no adjustments are necessary. However, those with five-speed manuals, six-speed automatics, or modified final drive ratios need to adjust specific PIDs within the Torque Pro app under “Settings -> Manage Custom PIDs”:
Five-Speed Manual Transmission:
zGear_1st: 3.163zGear_2nd: 1.888zGear_3rd: 1.333zGear_4th: 1.000zGear_5th: 0.814zGear_6th: 0
Six-Speed Automatic Transmission:
zGear_1st: 3.538zGear_2nd: 2.060zGear_3rd: 1.404zGear_4th: 1.000zGear_5th: 0.713zGear_6th: 0.582
Users with custom final drive ratios must modify the zGear_Final PID to reflect their specific setup. Additionally, “thresh” reference PIDs like “zGear_4Thresh” can be used with Torque Pro’s “On/Off” dashboard indicators to visually represent gear engagement.
Comprehensive Suite of PIDs
The AFX Products 34T5 provides a comprehensive array of PIDs, covering various vehicle systems for in-depth diagnostics:
- Engine Performance: Fuel Trim, Intake Air Temp, Manifold Pressure, Knock Retard, O2 Sensor Data, Throttle Position, etc.
- Transmission: Gear Indicator, Automatic Transmission Temperature, In Gear Switch.
- Emissions: EGR Purge Steps, EVAP System Monitoring.
- Electrical System: Generator Output Voltage, Battery Voltage.
- Other Systems: A/C System Status, Brake System Status, Tire Pressure and Temperature, Steering Wheel Angle.
The extensive list of available PIDs allows for comprehensive monitoring and diagnostics, empowering users to understand their vehicle’s performance and identify potential issues. The AFX Products 34T5 Bluetooth OBDII Scan Tool offers a valuable solution for both casual users and experienced mechanics seeking a reliable and feature-rich diagnostic tool.
Conclusion
The AFX Products 34T5 Bluetooth OBDII Scan Tool, with its recent updates addressing boost detection and incorporating a gear indicator, solidifies its position as a powerful diagnostic solution. The wide array of PIDs and customizable features make it a versatile tool for understanding and maintaining vehicle performance. Combining accurate data with user-friendly implementation, the AFX Products 34T5 provides a valuable asset for anyone seeking deeper insights into their vehicle’s operation.
