Key Parameters to Monitor

• Air-Fuel Ratio (AFR): Indicates the ratio of air to fuel in the combustion mixture. Optimal AFR ensures efficient combustion and prevents engine damage.
• Ignition Timing: Determines when the spark plugs fire in relation to piston position. Adjusting timing can improve power and fuel efficiency.
• Manifold Absolute Pressure (MAP): Measures the pressure in the intake manifold, indicating engine load.
• Throttle Position Sensor (TPS): Indicates the position of the throttle, reflecting driver demand.
• Engine Speed (RPM): Measures the rotational speed of the engine.
• Coolant Temperature (ECT): Indicates the temperature of the engine coolant, essential for preventing overheating.
• Intake Air Temperature (IAT): Measures the temperature of the air entering the engine, affecting air density and combustion.
• Knock Sensor Activity: Detects engine knocking or detonation, which can cause severe engine damage.
• Fuel Trims (Short Term and Long Term): Indicates adjustments the ECU is making to the fuel mixture to maintain the target AFR.

Interpreting Data Logs

1. Identify Trends: Look for patterns and trends in the data. For example, is the AFR consistently lean or rich under certain conditions?
2. Correlate Parameters: Understand how different parameters relate to each other. For instance, how does ignition timing change with engine speed and load?
3. Compare to Target Values: Compare the actual data to the target values set in the ECU calibration. Deviations indicate areas that need adjustment.
4. Analyze Knock Activity: If knock is detected, reduce ignition timing or enrich the fuel mixture to prevent engine damage.
5. Evaluate Fuel Trims: If fuel trims are consistently high or low, adjust the base fuel map to bring them closer to zero.
