What Is ECU Calibration?

ECU calibration is the process of determining the optimal calibration tables for an engine. This multistep process involves designing tests, collecting data, analyzing the data, and calibrating lookup tables to model the engine. This process helps to identify the optimal balance of engine performance, emissions, and fuel economy. You can also use models developed during ECU calibration for control design, hardware-in-the-loop (HIL) testing, or powertrain simulation.

ECU calibration engineers use tools for:

• Designing a test plan based on Design of Experiments
• Analyzing experimental data with a variety of empirical models
• Optimally calibrating lookup tables for the ECU
• Exporting calibrated models to use them in HIL testing
