PROBLEM TO BE SOLVED: To provide a method and a system for adapting an engine control parameters, capable of obtaining more accurate adaptive values, while reducing the man-hours for adaptation, in relation to the increase in requests for the number of engine control parameter and various engine characteristics values. SOLUTION: A load generated by an output shaft 24 of the engine 10 is absorbed by a dynamometer 31 to generate a condition that the engine 10 is mounted on a vehicle for simulation. The value of the control parameter is set variously to measure various characteristics value of the engine 10. On the basis of the result of the measurement, a model equation setting the relation between various control parameters and various characteristics values of the engine is obtained by an analysis tool 50. Adaptive value satisfying the request condition is computed on the basis of the model formula, and this model formula is stored in a database 52. Actual evaluation of a vehicle using the computed adaptation value, is performed to re-examine the request condition, and the adaptation value is re-computed, on the basis of the request condition and the model formula.
