Basic Logging Items

When performing data logging with your tuning device, there are several key parameters that you should monitor to gain valuable insights into your vehicle's performance. Below is a list of basic logging items that are crucial for effective data analysis:

• RPM - Revolutions per minute of the engine.
• Boost pressure - The pressure of air supplied to the engine by the turbocharger.
• Throttle position - The position of the throttle valve in the engine.
• AFR or lambda - Air-Fuel Ratio or lambda value indicating the mixture of air to fuel in the combustion chamber.
• Ignition advance - The timing of the spark plug firing, measured in degrees before top dead center.
• STFT - Short Term Fuel Trim, which adjusts the fuel mixture in real-time.

Monitoring these basic items will provide a comprehensive overview of your vehicle's operational dynamics, which is essential for effective tuning and performance optimization.
